Law of conservation of mass → all reactants are converted to products with nothing lost
Law of definite proportions → different samples of a pure compound always contain the same proportions of elements by mass
Match each observation to the law that it illustrates:
The C:O mass ratio of one compound is exactly double that of another compound.
The C:O mass ratio of a particular compound is the same regardless of the size or source of the sample.
When 3g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced.
Burning 10 g of propane produces twice as much carbon dioxide burning 5 g of propane
