<h3>Answer:</h3>

200 mL

<h3>Explanation:</h3>

Concept tested: Dilution formula

We are given;

  • Concentration of stock solution as 1.00 M
  • Volume of the stock solution as 50 mL
  • Molarity of the dilute solution as 0.25 M

We are required to calculate the volume of diluted solution;

  • The stock solution is the original solution before dilution while diluted solution is the solution after dilution.
  • Using the dilution formula we can determine the volume of diluted solution;

M1V1 = M2V2

Rearranging the formula;

V2 = M1V1 ÷ M2

     = (1.00 M × 50 mL) ÷ 0.25 M

     = 200 mL

Therefore, a volume of 200mL of 0.25 M solution could be made from the stock solution.

The reaction between SO2 and O2 to give SO3 was studied to determine the rate law for the reaction. The following results were o
Tom [10]

Answer : (b) The rate law expression for the reaction is:

\text{Rate}=k[SO_2]^2[O_2]

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

The general reaction is:

A+B\rightarrow C+D

The general rate law expression for the reaction is:

\text{Rate}=k[A]^a[B]^b

where,

a = order with respect to A

b = order with respect to B

R = rate  law

k = rate constant

[A] and [B] = concentration of A and B reactant

Now we have to determine the rate law for the given reaction.

The balanced equations will be:

2SO_2+O_2\rightarrow 2SO_3

In this reaction, SO_2 and O_2 are the reactants.

The rate law expression for the reaction is:

\text{Rate}=k[SO_2]^2[O_2]^1

or,

\text{Rate}=k[SO_2]^2[O_2]

Artemon [7]
A niche is the role an organism fills within its environment. What and where an animal eats are considered part of its niche. For instance, some birds, such as woodpeckers, eat insects in trees. This limits the bug population and keeps bugs from overtaking the environment.
