Question

if magnesium is cut up into smaller pieces, what happens to the time of reaction? less time of reaction than using a bigger piece same time of reaction as using a bigger piece more time of reaction than using a bigger piece

Explanation:

When a solid reactant (like magnesium) is cut into smaller pieces, its surface area increases. A larger surface area means more reactant particles are exposed to react, leading to a faster reaction rate. A faster reaction rate implies the reaction will take less time to occur compared to using a larger piece (which has a smaller surface area and slower reaction rate).

Answer:

A. Less time of reaction than using a bigger piece
