What statements are always true about limiting reactants? Select one or more:
1.The limiting reactant has a lower mass than other reactants.
2.The limiting reactant dictates the amount of product.
3.The limiting reactant is always the same for a given reaction.
4.There will be an excess of other reactants at the end of the reaction.
5.The limiting reactant is completely used up in the reaction.

5.The limiting reactant is completely used up in the reaction

Explanation:

The limiting reactant is completely used up in the reaction is the correct answer because a limiting reactant is a reactant in chemical reaction that is completely consumed or used up in the chemical reaction. Limiting reactant when it is completely used up limits the amount of products that will be formed. The reaction will be halted or will stop when the limiting reactant is totally used up.

a chemical reaction happens

explanation:

beta decay is the answer
