Lemon juice is _____.
an acid
a base
a neutral

Answers

Answer 1
An acid because of the content of citric and malic acids
Answer 2
Final answer:

Lemon juice is classified as an acid because it contains citric acid and has a pH well below 7.

Explanation:

Lemon juice is an acid. This is because it contains citric acid, which is a compound found in citrus fruits such as lemons and limes. Acids have certain characteristics; they taste sour, can conduct electricity when dissolved in water, and react with metals to produce hydrogen gas. According to the Bronsted-Lowry theory, an acid is a proton donor. The pH scale is used to determine the acidity or basicity of a solution. A solution with a pH less than 7 is considered acidic. For example, in a laboratory setting when testing pH, wine, with a pH of approximately 3.0, is labeled as acidic, whereas pure water is neutral with a pH of 7 and milk of magnesia is basic with a pH of 10.5. Therefore, given that the pH of lemon juice is well below 7, we can conclusively identify it as an acidic substance.

Waves we cannot actually see (unlike ripples) and those not needing a medium to travel within belong to this category of waves?

Answers

Final answer:

Electromagnetic waves can travel through a vacuum and do not require a medium. They include light, radio waves, and X-rays, among others.

Explanation:

The category of waves that cannot be seen and do not require a medium to travel through is known as electromagnetic waves. Unlike mechanical waves such as sound waves and water waves which need a medium (solid, liquid, or gas) to propagate, electromagnetic waves can travel through a vacuum. These consist of oscillations in electric and magnetic fields and include gamma rays, X-rays, ultraviolet waves, visible light, infrared waves, microwaves, and radio waves. A quintessential example of electromagnetic wave travel is visible light from distant stars reaching Earth through the vacuum of space.

Final answer:

Electromagnetic waves, including varieties like gamma rays and radio waves, do not require a medium to travel and can propagate through a vacuum at the speed of light.

Explanation:

The waves that cannot be seen and do not require a medium to travel through are known as electromagnetic waves. Unlike mechanical waves like sound and water waves, which require a medium such as air, water, or solids to travel through, electromagnetic waves can propagate through the vacuum of space. Some examples of electromagnetic waves include gamma rays, X-rays, ultraviolet waves, visible light, infrared waves, microwaves, and radio waves.

Electromagnetic waves are generated by the oscillations of electric and magnetic fields and they can move through a vacuum as they do not depend on a medium for their propagation. This characteristic allows electromagnetic waves to travel at a constant speed, known as the speed of light, which is approximately 2.99792458 × 108 m/s. Therefore, these waves are fundamentally different from mechanical waves, and this understanding is important for the study of physics and various applications in technology.

Fe(NO3)2 not sure how to get the oxidation numbers of all elements

Answers

Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.

The oxidation number of Fe in  Fe(NO3)2 is +3.

Final answer:

To find the oxidation numbers in Fe(NO3)2, we acknowledge that the sum is zero for a neutral compound. Each nitrate ion has an oxidation number of -1; thus, nitrogen is +5, and each oxygen is -2. Therefore, iron must have an oxidation number of +2 to balance the negative charge of the two nitrates.

Explanation:

To determine the oxidation numbers of elements in Fe(NO3)2, we follow the general rules for oxidation states. First, we know that the chemical compound as a whole is neutral, so the sum of all oxidation numbers in Fe(NO3)2 must be zero. Secondly, the oxidation number of oxygen is typically -2. In each nitrate ion (NO3−), there are three oxygen atoms contributing to a total of -6. The nitrate ion has a charge of -1, which means the nitrogen must have an oxidation number of +5 to balance the -6 from the oxygen atoms (x + 3(−2) = −1, x = +5).

Since there are two nitrate ions in Fe(NO3)2, this gives us a total negative charge of -2 from both nitrate ions. Consequently, the iron (Fe) must have an oxidation number of +2 to neutralize the charge from the nitrates (Fe2+). Thus, the complete set of oxidation numbers in Fe(NO3)2 is Fe2+ and two NO3− ions, with nitrogen being +5 and oxygen -2 in each nitrate ion.

what is the oxidation number of Cl in chlorate ion ClO3- ...?

Answers

You need the oxidation number for Cl, so we will use only the ClO3 1-. 

Oxygen is not in a peroxide. It is in "chlorate" so the oxidation number of oxygen is 2-. There are 3 oxygens in the ion. 2- x 3 = 6- total. The chlorate ion has a 1- charge so there are 5- charges to be balanced out by positive charges. That means that the Cl (the only other atom there) has to balance out the 5- left over by having a 5 + oxidation number. 

(Cl 5-) + (O3 6-) = ClO3 1-

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Final answer:

The oxidation number of Cl in the chlorate ion (ClO3-) is +5. This is determined by assigning oxygen an oxidation number of -2 and ensuring that the sum of oxidation numbers equals the ion's charge, which in this case is -1.

Explanation:

To determine the oxidation number of Cl in the chlorate ion (ClO3-), we apply the rules for assigning oxidation numbers. Here's how:

Oxygen is normally assigned an oxidation number of -2 (rule 3).In a polyatomic ion, the sum of the oxidation numbers of all the atoms must equal the charge on the ion (rule 4). With three O atoms, we have 3(-2) = -6 total for the oxygen atoms.Since the chlorate ion has a charge of -1, the Cl atom must have an oxidation number that will result in the total sum of -1 when combined with the total -6 from the O atoms.Therefore, the oxidation number for Cl is +5, as the equation Cl + 3(-2) = -1 simplifies to Cl = +5.

One canned juice drink is 15% orange juice; another is 5% orange juice. How many liters of each should be mixed together in order to get 10L that is 11% orange juice? ...?

Answers

Final answer:

To obtain 10L of 11% orange juice mix, we need 6L of 15% orange juice and 4L of 5% orange juice. We determine this by setting up and solving a system of linear equations based on the total volume and desired concentration.

Explanation:

To solve the problem of mixing two concentrations of orange juice to obtain 10 liters of a 11% orange juice solution, we will set up a system of equations. Let's define x as the amount of 15% orange juice and y as the amount of 5% orange juice. The total amount of the mixture should be 10 liters, so we have:

x + y = 10 ... (1)

Next, we set up the second equation based on the concentration of orange juice. Since we want the final concentration to be 11%, we can write the following equation:

0.15x + 0.05y = 0.11(10) ... (2)

Now we solve the system of equations. Multiplying equation (2) by 100 to make the numbers easier to work with, we get:

15x + 5y = 110

From equation (1), we can express y as:

y = 10 - x

Substituting y in equation (2), we have:

15x + 5(10 - x) = 110

15x + 50 - 5x = 110

10x = 60

x = 6

Now we find y using equation (1):

y = 10 - x

y = 10 - 6

y = 4

So, we need 6L of the 15% orange juice and 4L of the 5% orange juice to get 10L of 11% orange juice.

Answer:

Explanation: Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. Reduction reaction is defined as the reaction in which a substance gains electrons.

For the given options:

Option A: [tex]SO_2(g)+H_2O(l)\rightarrow H_2SO_3(aq)[/tex]

This is a combination reaction because two compounds are reacting to form a single compound.

Option B: [tex]CaCO_3(s)\rightarrow CaO+CO_2[/tex]

The above reaction is decomposition reaction because a single compound is breaking down into two compounds.

Option C: [tex]Ca(OH)_2(s)+H_2CO_3(l)\rightarrow CaCO_3(aq)+2H_2O(l)[/tex]

The above reaction is a neutralization reaction because an acid reacts with base to produce salt and water.

Option D: [tex]C_6H_{12}O_6(s)+6O_2(g)\rightarrow CO_2(g)+2H_2O(l)[/tex]

The oxidation state of oxygen changes from 0 to -2, it is gaining electrons. Thus, it is getting reduced and it undergoes reduction reaction. The carbon is getting oxidized and thus it undergoes oxidation reaction.

Thus, it is considered as redox reaction.

Hence, the correct answer is Option D.

How many moles of dipyrithione (C10H8N2O2S2) contain 8.2 x 10^24 atoms of N2?

Answers

Answer : The number of moles of dipyrithione are [tex]1.4\times 10^1[/tex] moles.

Explanation :

The given molecule is, [tex]C_{10}H_8N_2O_2S_2[/tex]

In this molecule, there are 10 atoms of carbon, 8 atoms of hydrogen, 2 atoms of nitrogen, 2 atoms of oxygen and 2 atoms of sulfur.

As we know that, 1 mole of substance contains [tex]6.022\times 10^{23}[/tex] number of atoms.

As, [tex]6.022\times 10^{23}[/tex] atoms of [tex]N_2[/tex] present in 1 mole of [tex]C_{10}H_8N_2O_2S_2[/tex]

So, [tex]8.2\times 10^{24}[/tex] atoms of [tex]N_2[/tex] present in [tex]\frac{8.2\times 10^{24}}{6.022\times 10^{23}}=13.6\approx 1.4\times 10^1[/tex] mole of [tex]C_{10}H_8N_2O_2S_2[/tex]

Therefore, the number of moles of dipyrithione are [tex]1.4\times 10^1[/tex] moles.

There are 6.8 moles of dipyrithione that contain 8.2 x 10²⁴ atoms of N₂, calculated using Avogadro's number and the composition of the molecule.

Avogadro's number (NA) is 6.022 x 10²³ mol⁻¹, which is the number of particles in one mole of a substance. Since each molecule of N₂ contains two nitrogen atoms,  divide the total number of nitrogen atoms by two to find the number of N₂ molecules, and then divide by Avogadro's number to find the moles of N₂.

First, calculate the number of moles of N₂ by using the formula

[tex]n = \frac{N}{N_A}[/tex]

It relates the number of particles N to the number of moles n. In this case, N is the total number of nitrogen atoms given (8.2 x 10²⁴ atoms), which we divide by 2 to account for N₂, and then divide this number by Avogadro's number (6.022 x 10²³ mol-1) to find the moles of N₂:

nN2 = (8.2 x 10²⁴ atoms) / (2 x 6.022 x 10²³ mol⁻¹) = 6.8 moles of N₂

Since dipyrithione has one N₂ unit per molecule, the number of moles of dipyrithione is the same as the number of moles of N₂:

6.8 moles of dipyrithione will contain 8.2 x 10²⁴ atoms of N₂.

Making the simplistic assumption that the dissolved NaCl(s) does not affect the volume of the solvent water, determine the constants m and b in the equation Molarity = mdensity + b that relates the NaCl molarity to the NaCl(aq) density. Take the density of water to be 1.00 g/mL and the molar mass of NaCl to be 58.5 g/mol.

I am having a very difficult time answering this question. There just doesn't seem to be enough information to determine the constants.

Answers

Answer:

m = 1,000/58.5 b = - 1,000 / 58.5

1) Variables

molarity: Mdensity of the solution: dmoles of NaCl: n₁mass of NaCl: m₁molar mass of NaCl: MM₁total volume in liters: VtVolume of water in mililiters: V₂mass of water: m₂

2) Density of the solution: mass in grams / volume in mililiters

d = [m₁ + m₂] / (1000Vt)

3) Mass of NaCl: m₁

    Number of moles = mass in grams / molar mass

    ⇒ mass in grams = number of moles × molar mass

        m₁ = n₁ × MM₁


4) Number of moles of NaCl: n₁

   Molarity = number of moles / Volume of solution in liters

   M = n₁ / Vt

   ⇒ n₁ = M × Vt


5) Substitue in the equation of m₁:

   m₁ = M × Vt × MM₁


6) Substitute in the equation of density:

    d = [M × Vt × MM₁ + m₂] / (1000Vt)


7) Simplify and solve for M

d = M × Vt × MM₁ / (1000Vt) + m₂/ (1000Vt)d = M × MM₁ / (1000) + m₂/ (1000Vt)

Making the simplistic assumption that the dissolved NaCl(s) does not affect the volume of the solvent water means 1000Vt = V₂  

d = M × MM₁ / (1000) + m₂/ V₂

        m₂/ V₂ is the density of water: 1.00 g/mL

d = M × MM₁ / (1000) + 1.00 g/mLM × MM₁ / (1000) = d - 1.00 g/mLM = [1,000/MM₁] d - 1,000/ MM₁

8) Substituting MM₁ = 58.5 g/mol

M = [1,000/58.5] d - [1,000/ 58.5]

Comparing with the equation Molarity = m×density + b, you obtain:

m = 1,000/58.5 b = - 1,000/58.5

The value of m is [tex]\boxed{{\text{1/molar mass}}\left({0.0170\;{\text{mol}}\cdot{{\text{g}}^{-1}}}\right)}[/tex] and the value of b is [tex]\boxed{{\text{mol/volume}}}[/tex].

Further Explanation:

The property is a unique feature of the substance that differentiates it from the other substances. It is classified into two types:

1. Intensive properties:

These are the properties that depend on the nature of the substance. These don't depend on the size of the system. Their values remain unaltered even if the system is further divided into a number of subsystems. Temperature, refractive index, molarity, concentration, pressure, and density are some of the examples of intensive properties.

2. Extensive properties:

These are the properties that depend on the amount of the substance. These are additive in nature when a single system is divided into many subsystems. Mass, enthalpy, volume, energy, size, weight, and length are some of the examples of extensive properties.

Density is defined as the ratio between mass and volume. Both mass and volume are the physical properties that are extensive in nature and their ratio comes out to be an intensive quantity that depends only on the nature of the substance, not on the amount of the substance. The formula to calculate the density of a substance is,

[tex]{\text{Density of substance}}\left({{\rho }}\right){\text{=}}\frac{{{\text{Mass of substance}}\left({\text{M}}\right)}}{{{\text{Volume of substance}}\left({\text{V}}\right)}}[/tex]

Molarity is a concentration term that is defined as the number of moles of solute dissolved in one litre of the solution. It is denoted by M and its unit is mol/L.

The formula to calculate the molarity of the solution is as follows:

[tex]{\text{Molarity of solution}}=\frac{{{\text{amount}}\;\left({{\text{mol}}}\right)\;{\text{of}}\;{\text{solute}}}}{{\;{\text{volume}}\left({\text{L}}\right)\;{\text{of}}\;{\text{solution}}}}[/tex]

The given expression is,

[tex]{\text{Molarity}}={\text{m}}\left({{\text{density}}}\right)+{\text{b}}[/tex]           …… (1)

Substitute the formula of given quantities in equation (1).

[tex]\frac{{{\text{mol}}}}{{{\text{Volume}}}}={\text{m}}\left({\frac{{{\text{mass}}}}{{{\text{Volume}}}}}\right)+{\text{b}}[/tex]                          …… (2)

Quantities with same units are added, subtracted, multiplied or divided. So two quantities on the right-hand side of equation (2) must have the same units and equation (2) becomes,

[tex]\frac{{{\text{mol}}}}{{{\text{Volume}}}}={\text{m}}\left({\frac{{{\text{mass}}}}{{{\text{Volume}}}}}\right)+{\text{m}}\left({\frac{{{\text{mass}}}}{{{\text{Volume}}}}}\right)[/tex]                                 …… (3)

Solve for units of m,

[tex]{\text{m}}=\frac{{{\text{mol}}}}{{{\text{mass}}}}[/tex]

Or it can be written as,

[tex]{\text{m}}=\frac{{\text{1}}}{{{\text{Molar mass}}}}[/tex]                               …… (4)

Substitute 58.5 g/mol for the molar mass of NaCl in equation (4).

[tex]\begin{aligned}{\text{m}}&=\frac{{{\text{1 mol}}}}{{{\text{58}}{\text{.5 g}}}}\\&=0.0170\;{\text{mol}}\cdot{{\text{g}}^{-1}}\\\end{aligned}[/tex]

The unit of b is equal to that of m(density). So its unit can be calculated as follows:

[tex]\begin{aligned}{\text{b}}&=\left({\frac{{{\text{mol}}}}{{{\text{mass}}}}}\right)\left({\frac{{{\text{mass}}}}{{{\text{Volume}}}}}\right)\\&=\frac{{{\text{mol}}}}{{{\text{Volume}}}}\\\end{aligned}[/tex]

I need help! how many moles are in 3.4*10^-7 grams of silicon dioxide, SiO2. I got 2.0^17 but I think it's wrong :(

Answers

Molar mass SiO2 = 28 + 32 = 60 

so moles sand = 3.4 x 10-7 / 60

what is the chemical formula for fluorine in standard state?

Answers

Fluorine in its standard state is F2.

Final answer:

The chemical formula for fluorine in its standard state is F₂, which is a diatomic gas due to fluorine's high electronegativity.

Explanation:

The chemical formula for fluorine in its standard state is F₂. Fluorine is a diatomic molecule, meaning it naturally pairs up with another fluorine atom to form a molecule in its most stable and common form, denoted as F₂ gas. Rule 3 of assigning oxidation states is vital for fluorine due to its strong electronegativity, which is the highest among all elements. Thus, the F-F molecule can provide a reference point for calculating oxidation states of other elements.

What mass of steam at 100 C must be mixed with 150 gram of ice at its melting point, in a thermally insulated container, to produce liquid water at 50 C?

Heat of fusion of water at its normal freezing or melting temperature = 333 kJ/kg
Heat of vaporization (or steam) = 2256 kJ/kg
Specific heat of water = 4180 J/kg K ...?

Answers

1. Since the system is thermally insulated, then the 

Heat given up by steam = Heat absorbed by ice 

Qs = Qi 

Qs = Ms(Hv) + Ms(Cp)(100 - 65) 

Qs = Ms(Hv) + Ms(Cp)(35) 

where 

Ms = mass of steam 
Hv = heat of vaporization of steam 
Cp = specific heat of water 

Qi = 0.350(Hf) + 0.350(Cp)(65 - 0) 

Qi = 0.350(Hf) + 22.75(Cp) 

where 

Hf = heat of fusion of ice 
Cp = specific heat of water (as previously defined) 

and since Qs = Qi, then 

Ms(Hv) + Ms(Cp)(35) = 0.350(Hf) + 22.75(Cp) 

I will stop my actual solution at this point. From hereon in, I trust that you can proceed with the rest of the solution. 

Simply, determine the following values -- Hv, Cp and Hf -- and substitute in the above equation. After substituting the appropriate values, then you can already solve for Ms -- the mass of steam. 






2.  m (2256 + 51 x 4.186) = 485 (333 + 49 x 4.186) 
m = 105.684 g

The ice will require two forms of heat: latent to melt and sensible to be heated to 50 °C.
Q(ice) = ml + mCpΔT
= 150 x 333 + 150 x 4.18 x 50
= 85950 Joules
The mass of steam must release this much energy in two forms: latent to fuse into water and then sensible to cool to 50 °C.
85950 = m(2256) + 4.18 x 50 x m
m = 34.9 grams of steam.
