Which substance is completely consumed in a chemical reaction?
Rudiy27

Answer:

Limiting Reactant

Explanation:

Observe the answer choices:

A) Limiting Reactant; a limiting reactant, as can be seen from the name, is the reactant that <em>limits</em> the amount of products can be made. This is because the reaction can only go on if there is enough reactants. However, the limiting reactant is the one that will run out first, so it's going to be completely consumed.

B) Reactant; a reactant is the thing that is being consumed in a reaction. However, reactants aren't always completely consumed. There's something called an excess reactant, which is essentially the opposite of a limiting reactant in that when the limiting reactant is used up, there's still some excess reactant left - because it's in <em>excess</em> / there's more than enough remaining. So, this is incorrect.

C) Products are the ones that are created during the chemical reaction, so they aren't consumed in any way. Thus, this is wrong.

The answer is limiting reactant.

Hope this helps!
