Question

1. what happens to the atoms of the reactants in a chemical reaction?

they recombine to form the products.
they change names.
they change into new atoms.
some are lost to the environment.

Explanation:

This is based on the law of conservation of mass, which states that atoms are neither created nor destroyed in a chemical reaction. Instead, the atoms of reactants rearrange (recombine) to form new substances (products). The other options are incorrect: atoms do not change names, do not turn into new atoms, and are not lost to the environment in a chemical reaction.

Answer:

They recombine to form the products.
