During the combustion of coal, the carbon in coal reacts with the oxygen in the atmosphere to form carbon dioxide. A, B, and C represent the masses of compounds either used up or formed by the combustion of coal.
A = 12 grams, B = 44 grams, C = 32 grams
Which of the following statements supports the conclusion that combustion of coal follows the law of conservation?
The total mass of A and C, which are carbon dioxide and oxygen, is equal to the mass of B, which is carbon.
The total mass of A and C, which are carbon and oxygen, is equal to the mass of B, which is carbon dioxide.
The total mass of B and C, which are carbon and oxygen, is greater than the mass of A, which is carbon dioxide.
The total mass of A and B, which are carbon and oxygen, is greater than the mass of C, which is carbon dioxide.
