Chapter 3.5, Problem 4CP

How is it possible for the combined masses of ${\text{CO}}_{\text{2}}{\text{ and H}}_{\text{2}}\text{O}$ produced in combustion to be greater than the mass of the compound that is burned?

a)

There is experimental error.

b)

Different balances are used to determine mass before and after combustion.

c)

Combustion \iolates the law of conservation of mass.

d)

Oxygen consumed in the combustion contributes to the mass of products.

e)

${\text{CO}}_{\text{2}}{\text{ and H}}_{\text{2}}\text{O}$ have greater molar masses than the compound that is burned.
