The equation that depicts a single replacement reaction would be: Zn(s) + 2HCl(aq)→ ZnCl2(aq) + H2(g)
<h3>Single replacement reactions</h3>
They are also known as single displacement reactions.
They are reactions in which one element takes the place of another in a compound. That is, one element replaces another in a compound.
Looking at all the reactions from A - D, one can see that the only reaction that exemplifies a single replacement reaction is D.
Here, Zn replaced H in HCl.

The question is incomplete, here is the complete question:
You need to prepare 250. mL of a 0.300 M aqueous solution of sucrose,
(aq), which is used frequently in biological experiments. Based on your answer above, measure out the amount of solid sucrose in the solution.
<u>Answer:</u> The mass of solid sucrose present in the solution is 25.7 grams.
<u>Explanation:</u>
To calculate the mass of sucrose, we use the equation used to calculate the molarity of solution:

Molarity of solution = 0.300 M
Molar mass of sucrose = 342.3 g/mol
Volume of solution = 250. mL
Putting values in above equation, we get:

Hence, the mass of solid sucrose present in the solution is 25.7 grams.
0.3 L is the final volume when M₁ = 3 M, V₁ = 0.125L, M₂ = 1.25M.
<h3>What is volume?</h3>
The amount of space occupied by a three-dimensional figure as measured in cubic units.
Given data:
M₁ = 3 M
V₁ = 0.125L
M₂ = 1.25M
V₂ = ?
Solution:
M₁V₁ = M₂V₂
3 M × 0.125L = 1.25M × V₂
V₂ = 0.3 L
Hence, 0.3 L is the final volume.
