Questions and Answers

What happens in a chemical reaction?

Atoms disappear from the reactants and appear in the products
Atoms are destroyed in the reactants
New atoms are created in the products
Atoms are reorganized into different arrangements (correct)

What is a balanced chemical equation?

An equation where atoms are created or destroyed
An equation that conforms to the law of conservation of matter (correct)
An equation with different arrangements of atoms
An equation with more atoms on the product side

Why is it important for a chemical equation to be balanced?

To rearrange atoms into different products
To allow for creation or destruction of atoms
To conform to the law of conservation of matter (correct)
