Question

. Given the balanced equation representing a reaction:

Fe(s) + 2HCl(aq) → FeCl₂ (aq) + H₂(g)
This reaction occurs more quickly when powdered
iron is used instead of a single piece of iron of the
same mass because the powdered iron
A) acts as a better catalyst than the single piece of
iron
B) absorbs less energy than the single piece of iron
C) has a greater surface area than the single piece of
iron
D) is more metallic than the single piece of iron

Answer 1

C

Step-by-step explanation:

The powdered iron has a greater surface area than the single piece of metal, allowing reactions to be done faster.

It's NOT A because in the reaction Iron is a reactant NOT a catalyst

It's NOT B because it's completely irrelevant to the question

It's NOT D because it's also not relevant to the question at hand
