what is the solute and the solution for a solvent of 44.8g and percent of 4.8
Answer:
The solute is 2.26 g and the solution is 47.1 gExplanation:
1) Percent formula: % = (mass of solue / mass of solution)×100
mass of solute = xmass of solvent = 44.8 gmass of solution = mass of solute + mass of solvent = x + 44.8Substitue the values in the percent formula:
4.8 = 100 x / (x + 44.8 g) 0.048 = x / (x + 44.8)0.048 (x + 44.8) = xx - 0.048x = 2.15x = 2.15 / ( 1 - 0.048) x = 2.26Mass of solute = 2.26 g ← answer
2) Mass of solution = mass of solute + mass of solvent
Mass of solution = 2.26g + 44.8g = 47.1 g ← answerAnswer:
[tex]\boxed{\text{Mass of solute = 2.26 g; mass of solution = 47.1 g}}[/tex]
Explanation:
[tex]\text{Mass percent} = \dfrac{\text{mass of solute }}{\text{mass of solute + mass of solvent}} \times 100 \, \%[/tex]
1. Calculate the mass of solute
Let x = mass of solute. Then
[tex]\begin{array}{rcl}4.8 & = & \dfrac{x}{x + 44.8} \times 100\\\\4.8(x + 44.8) & = & 100x\\4.8x + 215 & = & 100x\\215 & = & 95.2x\\\\x & = & \dfrac{215}{95.2}\\\\x & = & \textbf{2.26 g}\\\end{array}[/tex]
2. Calculate the mass of solution
Mass of solution = mass of solute + mass of solvent = (2.26 + 44.8) g
= 47.1 g
[tex]\boxed{\textbf{Mass of solute = 2.26 g; mass of solution = 47.1 g}}[/tex]
Explain the relationship between forward and backward reactions in equilibrium, and predict how changing the amount of a reactant (creating a tension) will affect that relationship.
Answer:
1- Equilibrium determines the rate of reactants and products at the same time.
General expression for equilibrium:
Reactants⇌ Products
2- At equilibrium, all the reactants and products are constant.
3- At equilibrium forward and reverse reaction does not stop, in fact, it continues at all times.
4- When the concentrations of reactants and products become equal dynamic equilibrium is obtained.
For example:
A + B ⇌ C + D
In this reaction, if the concentration of reactant A has increased the equilibrium will shift to the right to form more products.
If the concentration of reactant A has decreased the equilibrium will shift to the left in the backward direction to form reactants.
Answer:At equilibrium, the forward and backward reaction rate is the same.
Explanation:The equilibrium counteracts any change in the condition of the reactant or product. The le'chatalier principle highlights three main factors that affect the state of equilibrium. The three factors are: amount of moles, concentration and pressure.If the amount of reactant is increased, the equilibrium will shift to the right in order to create a balance between the forward and backward reaction and vice versa.
The student repeated the experiment using a higher concentration of acid. The same volume of acid and the same mass of magnesium ribbon were used. What volume of hydrogen gas would have been produced after 60 seconds?
Answer:
53 cm³
Explanation:
When the student used dilute sulfuric acid, the reaction was complete after 60 s, because no more hydrogen was formed in the next 10 s.
The reaction would go faster if the student used a more concentrated acid, but 53 cm³ of hydrogen is the most that would form.
A piece of copper has a temperature of 75.6 0C. When the metal is placed in 100.0 grams of water at 19.1 0C, the temperature rises by 5.5 0C. What is the mass of the metal?
The mass of the copper is approximately 1085.55 g.
To solve this problem, we can use the principle of heat transfer, which states that the heat lost by the metal (copper) is equal to the heat gained by the water.
The heat gained or lost by a substance can be calculated using the formula:
[tex]\[ Q = mc\Delta T \][/tex]
Where:
- Q is the heat gained or lost (in joules)
- m is the mass of the substance (in grams)
- c is the specific heat capacity of the substance (in J/g°C)
- [tex]\( \Delta T \)[/tex] is the change in temperature (in °C)
For copper, the specific heat capacity is approximately [tex]\( 0.385 \, J/g ^\circ C} \)[/tex], and for water, it's 4.18 J/g°C.
Let's denote:
- [tex]\( m_c \)[/tex] as the mass of the copper
- [tex]\( m_w \)[/tex] as the mass of the water
- [tex]\( \Delta T_c \)[/tex] as the change in temperature of the copper
- [tex]\( \Delta T_w \)[/tex] as the change in temperature of the water
Given:
- [tex]\( \Delta T_c = \Delta T_w = 5.5 \, ^\circ C} \)[/tex]
- [tex]\( c_c = 0.385 \, J/g^\circ C} \)[/tex] (specific heat capacity of copper)
- [tex]\( c_w = 4.18 \, J/g^\circ C} \)[/tex] (specific heat capacity of water)
- [tex]\( T_{c,i} = 75.6 \, ^\circ C} \)[/tex] (initial temperature of copper)
- [tex]\( T_{w,i} = 19.1 \, ^\circ C} \)[/tex] (initial temperature of water)
We can set up the equation:
[tex]\[ m_c \cdot c_c \cdot \Delta T_c = m_w \cdot c_w \cdot \Delta T_w \][/tex]
Solving for [tex]\( m_c \)[/tex]:
[tex]\[ m_c = \frac{m_w \cdot c_w \cdot \Delta T_w}{c_c \cdot \Delta T_c} \][/tex]
Substituting the given values:
[tex]\[ m_c = \frac{100.0 \, \text{g} \cdot 4.18 \, {J/g ^\circ C} \cdot 5.5 \, {^\circ C}}{0.385 \, {J/g^\circ C} \cdot 5.5 \, {^\circ C}} \][/tex]
[tex]\[ m_c = \frac{2299 \, \text{J}}{2.1175 \, \text{J}} \][/tex]
[tex]\[ m_c \approx 1085.55 \, \text{g} \][/tex]
So, the mass of the copper is approximately 1085.55 g.
What is the hydrogen ion and hydroxide ion concentration for a pOH of 3.557? Is the solution an acid or a base?
Answer:
Hydrogen ion concentration is 2.773E-4Mole per DM3
Hydroxide ion concentration is 4.093E-11
It is an acid
Explanation:
PH(H3O)=-LogH3O
PH=3.557
H3O=antilog of -3.557
antilog of -3.557=antilog (0.443 -4)
antilog0.443 ×antilog -4=2.773E-4mole per DM3.
(H3O)(OH)=10^-14
H30=2.773×10^-14
OH= 1.00E-14/2.773E-4
=4.093E-11
it is an acid since the concentration of hydrogen ion is more than the hydroxide ion
Answer:
[tex]3.606\times 10^{-11} M[/tex] is the hydrogen ion concentration.
0.0002773 M is the hydroxide ion concentration.
The solution has pH value more than 7 which means that it is base.
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution. Lower the value of pH more acidic will the solution.
Mathematically written as:
[tex]pH=-\log[H^+][/tex]
The pOH of the solution is defined as negative logarithm of hydroxide ions concentration in a solution. Lower the value of pOH more alkaline will the solution.
Mathematically written as:
[tex]pOH=-\log[OH^-][/tex]
The sum of ph and pOH is equal to 14.
pH + pOH = 14
We have:
Solution with pOH = 3.557
The pH of the solution = 14 - pOH = 10.443
[tex]pH=-\log[H^+][/tex]
[tex]10.443=-\log[H^+][/tex]
[tex][H^+]=3.606\times 10^{-11} M[/tex]
[tex]3.606\times 10^{-11} M[/tex] is the hydrogen ion concentration.
[tex]pOH=-\log[OH^-][/tex]
[tex]3.557=-\log[OH^-][/tex]
[tex][OH^-]=0.0002773 M[/tex]
0.0002773 M is the hydroxide ion concentration.
The solution has pH value more than 7 which means that it is base.
7. In the cycle, a virus integrates its DNA into the host's DNA, and its DNA is replicated when the host
DNA is replicated.
A. infectious
B. retroviral
C. lysogenic
D.lytic
Answer:
Its lysogenic cycle if a virus integrates its DNA into host cell.
Explanation:
Bacteriophages are the viruses which infect bacteria. Viruses are obligatory parasites which need host for their survival. Viruses which infect bacteria can either take up the lytic cycle or lysogenic cycle. Lytic as the name suggests involves the lysis of host bacterial cell after the replication of virus. Once the bacterial cell is lysed and the virions are released they invade another host bacterial cell. In the other case i.e. lysogenic cycle, the bacteriophage after infecting the host bacterial cell integrates its genome into the host cell genome. At this stage we call it as prophage. The viral genome gets replicated with the host cell machinery but does not produces the viral protein and remains dormant with in the host cell. The integrated genome of virus is passed on to the daughter cells as the cell division occurs. Once the bacterial host cell condition becomes progressively worse, the reproductive cycle of virus begins resulting in the lysis of host cell.
How is temperature related to the physical change of a substance?
Answer:
Temperature is a measure of the kinetic energy of particles in a substance. As temperature increases, the atoms or molecules in a substance gain energy. As temperature decreases, the particles lose energy. A change in the energy of particles causes a change in their arrangement. A change in the arrangement of particles can lead to a physical change.

Please help
To find the volume of hydrochloric acid (HCI) required to react completely with aluminum hydroxide (AI(OH)3), use the balanced chemical equation and stoichiometry. The equation is AI(OH)3 (s) + 3HCl (aq) -> AICl3 (aq) + 3H2O (l). Convert the mass of AI(OH)3 to moles, then use the mole ratio to find the volume of HCl.
Explanation:To find the volume of hydrochloric acid (HCI) required to react completely with aluminum hydroxide (AI(OH)3), we need to use the balanced chemical equation for the reaction and the stoichiometry of the reaction.
The balanced chemical equation is: AI(OH)3 (s) + 3HCl (aq) -> AICl3 (aq) + 3H2O (l)
From the equation, we can see that 1 mole of AI(OH)3 reacts with 3 moles of HCl. Given that the concentration of HCl is 0.500 mol/L, we can convert the mass of AI(OH)3 to moles, then use the mole ratio to find the volume of HCl:
Calculate the moles of AI(OH)3: 1.00 g AI(OH)3 * (1 mol AI(OH)3 / molar mass AI(OH)3)Use the mole ratio to find the moles of HCl: moles AI(OH)3 * (3 moles HCl / 1 mole AI(OH)3)Convert moles of HCl to volume using the concentration: moles HCl * (1 L / 0.500 mol)Plug in the values above to calculate the volume of HCl required.

Ionic solids such as sodium chloride are easily shattered, but metallic solids such as copper can be easily bent and shaped. This difference occurs because _________.
A. ionic solids have low melting points
B. covalent bonding between sodium and chlorine keeps the solid rigid
C. mobile electrons in the copper can shift without disrupting the solid
Answer:
C. mobile electrons in the copper can shift without disrupting the solid
Explanation:
Most of the properties of metals results from the metallic bonds between atoms of the metals. The bond forms from the attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by the atoms losing their outermost shell electrons due to their low ionizatin energy.
This is not so in ionic solids.

how can liquids be seperated by density
A the liquids are absorbed onto a paper
B the liquids are turned into seperate vapors
C the liquids are collected as they evaporate
D the liquids are allowed to seperate into layers
Answer:
D the liquids are allowed to seperate into layers
D. The liquids are allowed to separate into layers.
Explanation:Density refers to the weight of the substance. The substance which is light in weight remains at the top of the substance which is heavy or with more density. This principle is used for separation of liquid based on their density.
In the process, the liquid sample composed of various liquids of varying density is poured in a separating funnel. The setup is left as it is without disturbance for considerable period of time. Based upon the weight of the liquid it forms a layer in which liquid with high density settles at the bottom, whereas liquid with less density remain at the top.

DONE

Photo by Luigi Chiesa
Answer:
The correct choices are:
using accurate measurementsusing pure chemicalsperforming the reaction under the most ideal conditionsExplanation:
The theoretical yield is the maximum amount of product that could be obtained by the chemical reaction, from a given amount of reactants. You calculate the theoretical yield using the stoichiometry coefficients of the balanced chemical equation.
The percent yield is the ratio of the actual yield (the actual amount obtained) of a product to the theoretical yield for the same product, expressed as a percentage (i.e. multiplied by 100).
percent yield = actual yield × 100 / theoretical yieldAs the actual yield decrease (the numerator of the ratio), the percent yield decrease.
To increase the percent yield it is important:
using accurate measurementsusing pure chemicalsperforming the reaction under the most ideal conditionsUsing accurate measurements: if you do not add the correct amounts of each reactant, then the product obtained will not be what you can predict from the theoretical calculations and you will be wasteing one or other reactant, without reaching the maximum yield possible.
Using pure chemicals: if the chemicals are not pure, the amount of actual reactants will be lower than they should be, leading to a lower actual yield.
Performing the reaction under the most ideal conditions: the actual rate of reactions depend on the conditions: temperature and pressure are the most commons. Since, temperature and pressure may change that rate of reactions, you should find and use the most ideal conditions to get the greatest actual yield.
Adding water, can just dilute the reactants and would decrease the rate of reaction, which would not be helpful to increase the yield.
Answer is using accurate measurements
using pure chemicals
performing the reaction under the most ideal conditions
what is the predictided change in the boiling point of water when 1.5 g of barium chloride (BaCl2) is dissolved in 1.5 Kg of water
Answer:
0.0074 °C.
Explanation:
Adding solute (BaCl₂) to water causes elevation of boiling water of water (collegative properties).We can predict the change in the boiling point (ΔTb) of water using the relation:ΔTb = i.Kb.m,
where, ΔTb is the elevation in boiling water.
i is van 't Hoff factor, The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.
i for BaCl₂ = 3/1 = 3.
Kb is the molal elevation constant of water (Kb = 0.512 °C/m).
m is the molality of the solution.
molality (m) is the no. of moles of solute dissolved in 1.0 kg of solvent.m = (no. of moles of BaCl₂)/(mass of water (kg)) = (mass/molar mass of BaCl₂)/(mass of water (kg)) = (1.5 g/208.23 g/mol)/(1.5 kg) = 0.0048 m.
∴ ΔTb = i.Kb.m = (3)(0.512 °C/m)(0.0048 m) = 0.0074 °C.

The trend for ionization energy is a general increase from left to right across a period. However, magnesium (Mg) is found to have a higher first ionization energy value than aluminum (Al). Explain this exception to the general trend in terms of electron arrangements and attraction/repulsion
Answer:
Explanation:
The noticeable exception in the trends of ionization energy of Mg and Al can best be explained using the arrangements of the electrons in the sub-levels.
Mg with 12 electrons has an electronic configuration of 2,8,2 = 1S²2S²2P⁶3S²
Al with 13 electrons has an electronic configuration of 2,8,3 = 1S²2S²2P⁶3S²3P¹
Lets take a little peep into what ionization energy is.
Ionization energy is a measure of the readiness of an atom to lose electron. The amount of energy needed to remove an electron is called the ionization energy. In this regard, the first ionization energy is the energy need to remove the valence or the most loosely held electron in an atom.
The magnitude of the ionization energy depends on a number of factors. The most important to our discuss here are:
Nuclear chargeAtomic radiusSublevel accomodating the electron to be removedSpecial stability of filled or half-filled sublevels.The arrangement of electrons in Mg confers a special stability on it because of the filled sublevel.
The maximum number of electrons in each sub-levels are:
s-orbital = 2 electrons
p- orbital = 6 electrons
d - orbital = 10 electrons
f - orbital = 14 electrons
In Mg, 1S²2S²2P⁶3S² , the outermost s-sublevel have 2 electrons and s-orbital can accomodate a maximum of 2 electrons in this subshell. This makes the arrangement stable.
For Al, 1S²2S²2P⁶3S²3P¹, the outermost p-subshell houses just one electron but it can accommodate a maximum of 6 electrons. This arrangement is unstable.
Due to this electron arrangements, Mg would have a very stable configuration and a greater first ionization energy compared to Al.
What is insulin's structure?
a.quaternary
b.secondary
c.primary
d.tertiary
Insulin has a complex structure that involves primary, secondary, tertiary, and quaternary levels, with its three-dimensional tertiary structure being essential for its biological function.
Explanation:The structure of insulin can be described in terms of primary, secondary, tertiary, and quaternary levels. The primary structure refers to its amino acid sequence. Insulin exhibits a secondary structure through regions of alpha-helices and beta-sheets. The tertiary structure of insulin is its unique three-dimensional shape resulting from the folding of the protein, and is essential for its biological function. Finally, insulin may also exhibit a quaternary structure when two insulin monomers (A and B chains) come together, stabilized by disulfide bonds and other interactions, as seen in its storage form within the body.
