Question

balance of atoms question: which statement correctly explains why the ashes of burnt paper have less mass than the original paper? (1 point) the ash is created from new atoms that have less mass than the paper. some of the atoms in the paper became gases. other atoms combine with the paper to produce the ash. some of the atoms in the paper are destroyed when it burns.

Explanation:

According to the law of conservation of mass in chemistry, during a chemical - change like burning paper, atoms are not created or destroyed. When paper burns, some of the substances in the paper react with oxygen and form gaseous products (such as carbon - dioxide and water vapor) that escape into the air. So the remaining ash has less mass.

Answer:

Some of the atoms in the paper became gases.
