Yasmin's teacher asks her to make a supersaturated saline solution. Her teacher tells her that the solubility of the salt is 360 g/L at room temperature (25 °C).
How can Yasmin make a supersaturated saline solution?
She can add 380 g of salt to 1 L of hot water (75 °C) and stir until all the salt dissolves. Then, she can carefully cool the solution to room temperature (25 °C).
She can add 360 g of salt to 1 L of room temperature water (25 °C) and stir the solution until all the salt dissolves.
She can add 380 g of salt to 1 L of cold water (5 °C) and stir the solution until most of the salt dissolves. Then, she can carefully heat the solution to room temperature (25 °C).
She can add 380 g of salt to 1 L of room temperature water (25 °C) and let the solution sit for 24 hours, so the salt dissolves.
Answer:
She can add 380 g of salt to 1 L of hot water (75 °C) and stir until all the salt dissolves. Then, she can carefully cool the solution to room temperature.
Explanation:
A supersaturated solution contains more salt than it can normally hold at a given temperature.
A saturated solution at 25 °C contains 360 g of salt per litre, and water at 70 °C can hold more salt.
Yasmin can dissolve 380 g of salt in 1 L of water at 70 °C. Then she can carefully cool the solution to 25 °C, and she will have a supersaturated solution.
B and D are wrong. The most salt that will dissolve at 25 °C is 360 g. She will have a saturated solution.
C is wrong. Only 356 g of salt will dissolve at 5 °C, so that's what Yasmin will have in her solution at 25 °C. She will have a dilute solution.

which of the following is a solution
A- Brewed coffee
B-Tomato juice
C- ranch salad dressing
D- muddy water
Answer: Option (A) is the correct answer
Explanation:
When a solute completely dissolves a solvent with uniform composition then it results in a homogeneous mixture which is also known as a solution.
For example, coffee is brewed with water then coffee dissolves completely and uniformly into the water making a clear solution.
Whereas in a tomato juice particles remain suspended and it is called a suspension.
Ranch salad dressing is a heterogeneous mixture as particles are non-uniformly distributed.
Muddy water is also a suspension as particles settle at the bottom after some time.
Therefore, we can conclude that out of the given options brewed coffee is a solution.

Explanation: The answer is 75 g because due to the law of the conservation of mass no mass can be lost. So if you are making that t=mixture the mass will be the three weights combined because you are combining those three things.
an alloy contains 66 g of pure zinc. what is the percentage of zinc in the alloy? express your answer to two significant figures and include the appropriate units.
Due to lack of total mass information of the alloy, we cannot calculate the percentage of zinc directly. Instead, for a zinc-and-oxygen compound with a known mass, the percentage of zinc can be found by dividing the mass of zinc by the total mass of the compound and multiplying by 100, which in a given example, results in approximately 80.35% zinc by mass.
To calculate the percentage of zinc in the alloy, we need to know the total mass of the alloy. Since only the mass of pure zinc (66 g) is given and not the total mass of the alloy, we can't calculate the percentage directly. However, we can calculate the percentage composition of zinc in a compound using its mass before and after decomposition. In the given reference, a 20.00 g sample of a zinc-and-oxygen compound is decomposed and 16.07 g of zinc remains, which is used to determine the percent composition.
To calculate the percentage of zinc in the compound:
Divide the mass of zinc (16.07 g) by the total mass of the compound (20.00 g).
Multiply the result by 100 to get the percentage.
So the calculation will be (16.07 g \/ 20.00 g) \\times 100%, which gives about 80.35%. This means that by mass, the compound is mostly zinc.

Explanation:
David has two containers of two different gases at the same temperature and pressure. David could assume all of following EXCEPT _________.
A. when the temperature is increased, the volume of both containers will increase
B. when the pressure is increased, the volume of both containers will decrease
C. both containers contain the same number of gas particles
D. when the pressure is decreased, the temperature of both containers will increase
Answer:
David could not assume that:when the pressure is decreased, the temperature of both containers will increase (option D).
Explanation:
Since this question has only one answer, you must assume that both containers are identical, i.e. have the same volume.
Using the ideal gas equation pV = nRT you can conclude that pressure and temperature are directly related, i.e. if the pressure is decreased, the temperature will decrease proportionally, which is opposite to the assumption that when the pressure is decreased, the temperature of both containers will increase.
On the other hand, from the same equation, you can tell the relationship between the other variables and conclude that the other choices are valid assumptions:
A. when the temperature is increased, the volume of both containers will increase:
Correct: pV = nRT shows that volume and temperature are directly related: when T increase, V increase)
B. when the pressure is increased, the volume of both containers will decrease
Correct: pV = nRT shows that p and V and inversely related, so when p is incrased, V will decrease.
C. both containers contain the same number of gas particles
Correct, only if the two containers are identical: since the two containers of the two different gases are at the same temperature and pressure, the equation pV = nRT, shows that if the volumes are equal the number of particles are the same.
David cannot assume option C, which states both containers contain the same number of gas particles since he only knows the temperature and pressure of both gases. Without knowledge of the volume, he cannot determine the number of particles via the Ideal Gas Law.
Explanation:In this question, David does not have enough information to assume that C. both containers contain the same number of gas particles. This is because simply having the same temperature and pressure for two different gases does not confirm they have the same number of particles.
In the units of Ideal Gas Law, which states PV = nRT, 'P' stands for pressure, 'V' is volume, 'n' indicates number of moles i.e., the number of particles, 'R' is the universal gas constant, and 'T' is Temperature.
From this, we can see that the number of gas particles is proportional to the pressure and volume, and inversely proportional to the temperature. Therefore, without information about volume, we can not determine if both containers have the same number of particles.
The other possibilities regarding pressure, temperature, and volume changes are governed by the principles of gas laws, such as Boyle's, Charles', and Gay-Lussac's laws.

what is the Bronsted Acid in the following equation:
NO2- +H2O \longrightarrow ⟶ HNO2 + OH-
Answer:
[tex]NO_2^-[/tex]
Explanation:
[tex]NO_2^- + H_2O\rightarrow HNO_2+OH^-[/tex]
A Bronsted acid is a substance which donates protons to another substance.
In this case, [tex]H_2O[/tex] is donating a proton to the nitrite ion.
Thus, it is the Bronsted acid in this equation.
Answer:
H₂O is the Bronsted Acid in this reaction.
Explanation:
A Brønsted-Lowry acid is any species capable of donating a proton (H+).
A Brönsted-Lowry base is a substance capable of gaining or accepting a proton (H+).
In this way, the acid-base reaction is one in which a transfer of protons from the acid to a base occurs.
This theory, unlike Arrhenius theory does not require the presence of water as a solvent, but includes any type of solvent.
The conjugate acid of the base, is the one that is formed when the base receives an H +
The conjugate base of the acid is the base formed when the acid yields an H +.
In this case, you have:
NO₂⁻ + H₂O → HNO₂ + OH⁻
Water acts as an acid yielding a proton to NO₂⁻, which in turn acts as a base and forms the HNO₃ conjugate base.

Explanation:
a) Find [H⁺]
∵ [H⁺] [OH⁻] = 10⁻¹⁴.
∴ [H⁺] = 10⁻¹⁴/ [OH⁻] = 10⁻¹⁴/ (3.16 x 10⁻¹¹ M) = 3.16 x 10⁻⁴ M.
b) What is the pH?
∵ pH = - log[H⁺].
[H⁺] = 3.16 x 10⁻⁴ M.
∴ pH = - log(3.16 x 10⁻⁴ M) = 3.5.
c) Is the solution acidic, basic, or neutral?
We can determine the nature of the solution, acidic, basic or neutral, from the value of the pH.pH is a scale from 0 to 14.
If pH < 7, the solution is acidic.If pH = 7, the solution is neutral.If pH > 7, the solution basic.∵ pH = 3.5 < 7.

For brevity
Ground State Electron Configuration:
Naturally, atoms use the lowest energy possible, and this state in which an atom is at the lowest energy level possible is the Ground State.
Final answer:
The ground state electron configuration for vanadium (V) is [Ar] 4s² 3d³, as V follows the 3d orbital filling sequence after Ca and before Cr with its half-filled 3d5-shell.
Explanation:
The ground state electron configuration for the element vanadium (V), which has the atomic number 23, is a topic related to the transition elements in chemistry. The electronic configuration for vanadium can be tricky due to the closeness in energy levels of the 4s and 3d orbitals. However, from the given reference information and understanding the sequence of orbital filling for transition elements, we can deduce that after potassium (K) and calcium (Ca), where the 4s orbital is filled, the 3d electrons begin to be filled for scandium (Sc), titanium (Ti), and then vanadium (V). Keeping in mind the discontinuity that occurs at chromium (Cr), vanadium's ground state configuration can be written using the knowledge that V comes just before Cr. Therefore, vanadium’s electron configuration is [Ar] 4s² 3d³, following the 3d orbital filling after Ca and before the half-filled 3d5-shell configuration of Cr.
In your own words, write a paragraph to compare and contrast endothermic and exothermique reactions. Give at least one example of each
Please answer ASAP!! Don’t google it
Explanation:
Endothermic vs. Exothermic Reactions. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. Conversely, an exothermic reaction is one in which energy is released from the system into the surroundings. The terms are commonly used in the physical sciences and chemistry.
Final answer:
Endothermic reactions absorb energy, causing environmental temperature to decrease, like in photosynthesis, while exothermic reactions release energy, increasing environmental temperature, as seen in the combustion of substances like paper. Energy changes in these reactions are due to bond forming and breaking, with endothermic reactions needing energy input and exothermic reactions releasing energy.
Explanation:
Chemical reactions can broadly be classified into two types: endothermic and exothermic reactions. Endothermic reactions absorb energy from the surroundings, often in the form of heat, leading to a temperature decrease in the environment. A classic example of an endothermic reaction is photosynthesis in plants, where solar energy is absorbed to convert carbon dioxide and water into glucose and oxygen. On the other hand, exothermic reactions release energy, usually causing a temperature increase.
Combustion of substances, such as burning paper, is an exothermic reaction because it releases heat into the surroundings. The energy difference between the reactants and products is what drives these endothermic and exothermic processes, with the former having higher potential energy in the products and the latter having higher potential energy in the reactants.
When considering the energy change during a chemical reaction, it's the formation and breaking of chemical bonds that result in energy being absorbed or released. Endothermic reactions require energy to break bonds within the reactants, leading to a higher potential energy in the products compared to the reactants.
Conversely, exothermic reactions release energy when new bonds are formed in the product molecules, which possess less energy than the reactants. If we were to draw energy graphs for these reactions, an endothermic reaction graph would depict an upward curve from reactants to products, reflecting an input of energy, whereas an exothermic reaction graph would show a downward curve, indicating that energy is released.

Which of the following is true for a gas under conditions of very low temperature?
PV/nRT = 1. because all gases behave at ideally at very low temperatures.
PV/nRT = 1, because the actual volume of the gas molecules becomes considerable.
PV/nRT = 1, because the low temperature slows down the particles
PV/nRT = 1, because particles are unable to overcome intermolecular attractions.
Answer:
Because the particles are unable to overcome intermolecular attractions is the answers.
Explanation:
Answer: Option (d) is the correct answer.
Explanation:
It is known that gases at low pressure and high temperature behave ideally as they do not have any intermolecular forces of attraction between them.
Whereas it temperature is decreases or lowered then molecules of the gas will come closer to each other.
As a result, there will be increase in the intermolecular forces of attraction and very less or no repulsion will take place between the molecules. Hence, gas will behave non-ideally at low temperature.
Thus, we can conclude that it is true for a gas under conditions of very low temperature that PV/nRT = 1, because particles are unable to overcome intermolecular attractions.

Violet light has a frequency of 7.26 * 1014 Hz and travels at a speed of 3.00 * 108 m/s.
The wavelength of violet light, rounded to the nearest nanometer, is
nm.
c=λν
3*10^8 m/s * 10^9 nm/m / 7.26*10^14 s^-1= λ
=413.22 nm
λ=413 nm
Answer : The wavelength of violet light is, 413 nm
Explanation :
Formula used :
[tex]\nu=\frac{c}{\lambda}[/tex]
where,
[tex]\nu[/tex] = frequency of violet light = [tex]7.26\times 10^{14}Hz=7.26\times 10^{14}s^{-1}[/tex]
As we know that, [tex]Hz=s^{-1}[/tex]
[tex]\lambda[/tex] = wavelength of violet light
c = speed of light = [tex]3.00\times 10^8m/s[/tex]
Now put all the given values in the above formula, we get:
[tex]7.26\times 10^{14}s^{-1}=\frac{3.00\times 10^8m/s}{\lambda}[/tex]
[tex]\lambda=\frac{3.00\times 10^8m/s}{7.26\times 10^{14}s^{-1}}[/tex]
[tex]\lambda=4.13\times 10^{-7}m=4.13\times 10^{-7}\times 10^9nm=413nm[/tex]
conversion used : [tex]1m=10^9nm[/tex]
Therefore, the wavelength of violet light is, 413 nm

The potential energy diagram shows the gain and loss of potential energy as water molecules decompose into hydrogen and oxygen. Label the parts of the diagram
Answer:
The diagram with the five labels of the parts is in the image attached. Please, see the image.Explanation:
1) General explanation: a potential chemical energy diagram is used to show how the reactants gain energy until they reach the activation energy, form the activated complex, and release part of the energy to form the products.
The difference between the chemical potential energy of the products and the reactants is the enthalpy of the reaction:
ΔH rxn = ΔH products - ΔH reactants.The labels that correspond to each part of the diagram are explained next.
2) Reactants:
This is the substances at the start, so they appear on the left bottom side of the diagram.
3) Activation energy:
It is the energy that the reactants must reach (the highest point) in order to the reaction occurs.
4) Activated complex:
This is the intermediate state and of highest energy. The reactants have formed a complex at mid way between the reactants and the products.
5) Products:
These are the substances formed when the reaction is completed. They are lower in energy than the activated complex. They can be either higher or lower in energy than the reactants. The products are shown to the right of the diagram.
6) Enthalpy of the reaction:
The enthalpy of the reaction is the difference in energy of the products and the reactants. In this case, since, the products are higher in energy, it means that the reaction absorbed energy and it is an endothermic reaction.
The parts of the diagrams are reactants, activated complex, activation energy, enthalpy of reaction, and products.
Reactants: The leftmost point on the curve. These are the molecules before a chemical reaction occurs.Activated Complex: The peak of the curve. This is a temporary, unstable arrangement of atoms where old bonds are breaking and new bonds are forming.Activation Energy: Represented by the arrow pointing upwards from the reactants to the activated complex. This is the energy needed to form the activated complex.Enthalpy of Reaction: Shown by an arrow pointing downwards from the reactants to the products. It indicates the overall energy change in the reaction.Products: The rightmost point on the curve. These are the molecules that are formed after the reaction.In an experiment, a student wants to increase the rate of a reaction that involves gases. Which change to the reactants would

Increase the volume to decrease pressure and to increase concentration.
Increase the volume to increase pressure and to decrease concentration.
O Decrease the volume to decrease pressure and to increase concentration.
O Decrease the volume to increase pressure and to increase concentration.
Answer:
The last option: Decrease the volume to increase pressure and to increase concentration.Explanation:
You can support your choice on basis of the collision theory.
According to the collision theory, the chemical reactions happen when the molecules collide with each other, in the correct orientation and with enough kinetic energy to overcome the activation energy.
As consequence, the larger the number of collisions the larger the rate of a reaction.
In the case of a reaction that involves gases, decreasing the volume, will increase the pressure and the concentration (volume is inversely related to both the pressure and the concentration) causing the molecules to be closer to each other and to collide with higher frequency, this is you will expect more collisions, and so an increase on the rate of the reaction. That is expressed by the last choice: decrease the volumen to increase pressure and to increase concentration.
