fe(s) + 2hcl(aq) → fecl2(aq) + h2(g)
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
(1) acts as a better catalyst than the single piece of iron
(2) absorbs less energy than the single piece of iron
(3) has a greater surface area than the single piece of iron
(4) is more metallic than the single piece of iron
