Question

When paper burns, the paper combines with oxygen to form carbon dioxide and water vapor. How does the mass of carbon dioxide plus water vapor compare with the mass of the paper plus oxygen?

The mass of carbon dioxide plus water vapor is greater than that of paper plus oxygen.

The mass of carbon dioxide plus water vapor is less than that of paper plus oxygen.

The mass of carbon dioxide plus water vapor is identical to that of paper plus oxygen

Answer 1

Major hint - review conservation of matter/mass

Answer 2

is it The mass of carbon dioxide plus water vapor is identical to that of paper plus oxygen

Answer 3

Yup that’s correct

Conservation of mass—> mass of reactants = mass of products

Answer 4

thank you!!
