The solid that has the lowest solubility at 10°C is substance D

A solubility curve is a graphic representation of a solute's solubility in a particular solvent at different pressures and temperatures. A material's solubility, which is often expressed in grams per 100 milliliters (g/100 mL) of solvent, is the maximum quantity of the substance that can dissolve in a given amount of solvent at a particular temperature and pressure.

This is because, the solubility of the substance D as we can see from the curve is closest to zero around 10°C .

Answer:

The periodic table is a set of elements organized by their atomic number, from lowest (hydrogen 1) to highest (oganesson 118). That number is the amount of protons in the nucleus of an atom of the element. The table is split into three groups of elements (metals, nonmetals and metalloids). As you go down the table the elements are more reactive.

Answer:

The new volume of the balloon will be approximately 77.7 mL (3 s.f.).

Explanation:

We can assume that the pressure remains constant, since the balloon is not being compressed or expanded, and is simply being exposed to a different temperature. Therefore, to solve this problem, we can use Charles's Law, which relates the volume and temperature of a gas.

\(\boxed{\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}\)

where:

Given the balloon is initially filled with 47 mL of hydrogen gas at 276 K, and its temperature is raised to 456 K:

Substitute the given values into the formula:

\(\implies \sf \dfrac{47\;mL}{276\;K}=\dfrac{V_2}{456\;K}\)

Solve for V₂:

\(\implies \sf \dfrac{47\;mL}{276\;K} \cdot 456\;K=\dfrac{V_2}{456\;K} \cdot 456\;K\)

\(\implies \sf V_2=\dfrac{47\;mL\cdot 456\;K}{276\;K}\)

\(\implies \sf V_2=77.6521739...\;mL\)

\(\implies \sf V_2=77.7\; mL\; (3\;s.f.)\)

Therefore, the new volume of the balloon will be approximately 77.7 mL when the temperature is raised to 456 K.

We can use Charles' Law to solve this problem, which states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature:

where:

Solving for \(\sf V_2\), we get:

\(\begin{aligned}\sf V_2& =\sf \dfrac{(V_1 \cdot T_2)}{T_1} \\& =\sf \dfrac{(47\: mL \cdot 456\: K)}{276\: K} \\ & = \boxed{\bold{\:77.7\: mL\:}} \end{aligned}\)

Therefore, the new volume of the balloon at a temperature of 456 K is 77.7 mL.

Cells have distinct and different jobs and functions in the body.

The number of bonds for an atom can change depending on the chemical reaction it undergoes.

Atoms can form chemical bonds with other atoms to achieve a more stable state. The number of bonds an atom can form is determined by the number of valence electrons it has. Valence electrons are the outermost electrons that are involved in bonding. When an atom undergoes a chemical reaction, it can either gain or lose electrons, or share electrons with other atoms to form new bonds. As a result, the number of bonds for that atom can change.

For example, when a hydrogen atom (H) and a chlorine atom (Cl) react, they form a hydrogen chloride (HCl) molecule. In this reaction, the hydrogen atom shares one of its electrons with the chlorine atom, forming a covalent bond. As a result, the hydrogen atom goes from having one bond to two bonds, while the chlorine atom goes from having one bond to three bonds.

The appearance of the solution may change slightly, depending on the initial color of the solution and the solubility of the products formed.

If 6 M NaOH is added instead of 6 M NH₄OH, the solution would become more basic. NaOH is a stronger base than NH₄OH and therefore would react more strongly with the K₂C₂O₄.

Balanced chemical equation for the reaction between K₂C₂O₄ and NaOH will be;

K₂C₂O₄ + 2NaOH → 2KOH + Na₂C₂O₄ + H₂O

As NaOH is added to the solution, it will react with K₂C₂O₄ forming Na₂C₂O₄, KOH and water. This will result in the production of more hydroxide ions, which will increase the pH of the solution.

However, the increase in pH will be noticeable and the solution may become more cloudy due to the formation of a precipitate of Na₂C₂O₄.

Approximately 18.4832 mL of 0.250 M NaOH is required to neutralize 30.4 mL of 0.152 M HCl.

To determine the volume of 0.250 M NaOH required to neutralize 30.4 mL of 0.152 M HCl, we can use the concept of stoichiometry and the balanced chemical equation for the neutralization reaction between NaOH and HCl:

NaOH + HCl -> NaCl + H2O

From the balanced equation, we can see that the stoichiometric ratio between NaOH and HCl is 1:1. This means that for every mole of NaOH, we require an equal number of moles of HCl to neutralize.

First, let's calculate the number of moles of HCl present in the given volume:

Moles of HCl = concentration of HCl * volume of HCl

= 0.152 M * 30.4 mL

= 4.6208 mmol (millimoles)

Since the stoichiometric ratio is 1:1, the number of moles of NaOH required to neutralize the HCl is also 4.6208 mmol.

Now, let's calculate the volume of 0.250 M NaOH needed to contain 4.6208 mmol:

Volume of NaOH = (moles of NaOH) / (concentration of NaOH)

= 4.6208 mmol / 0.250 M

= 18.4832 mL

Therefore, approximately 18.4832 mL of 0.250 M NaOH is required to neutralize 30.4 mL of 0.152 M HCl.

The accurate relationship between the velocity of a reaction and the rate constant of a reaction depends on the type of reaction. For a first-order reaction, the rate constant is proportional to the velocity of the reaction, and independent of substrate concentration. Therefore, option C is correct.

In a first-order reaction, the rate constant of a reaction is equal to the velocity of the reaction divided by the concentration of substrate. This means that as the concentration of substrate decreases, the velocity of the reaction will decrease as well, but the rate constant will remain constant. For second-order reactions, the rate constant is equal to the velocity of the reaction divided by the concentration of both substrates. It is important to note that the relationship between velocity and rate constant can differ depending on the order of the reaction. For both first-order and second-order reactions, the concentration of substrate affects the velocity of the reaction, but the rate constant is specific to the reaction type and independent of substrate concentration.

Options A and B are therefore incorrect. Option D is also incorrect, as it pertains to a second-order reaction with multiple substrates, which is not specified in the question.

The balanced reaction equation for the bromination of stilbene using pyridinium tribromide is: C14H12 + Br2 → C14H10Br2 In this reaction, stilbene (C14H12) reacts with bromine (Br2) to form dibromostilbene (C14H10Br2).

The balanced reaction equation for the bromination of stilbene using pyridinium tri-bromide is: Stilbene + 3 Br2 + Pyridinium tribromide → 2,3,4,5-tetrabromostilbene + Pyridinium bromide In the given procedure, the amount of stilbene is not mentioned, so we cannot determine the limiting reagent directly.

To find the limiting reagent in a given procedure, you will need to compare the stoichiometric ratios of the reactants to determine which one will be completely consumed first during the reaction.

To do this, you'll need the amounts (usually in moles or grams) of both stilbene and pyridinium tribromide used in the procedure.

However, we can assume that the amount of pyridinium tri-bromide is in excess, and the limiting reagent will be the reactant that is completely consumed first.
