Question

which observation illustrates the law of coservation of mass?

Which observation illustrates the law of conservation of mass? The C:O mass ratio of one compound is exactly double that of another compound. When 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced. The C:O mass ratio of a particular compound is the same, regardless of the size or source of the sampl O Burning 10 g of propane produces twice as much carbon dioxide as burning 5 g of propane.

Answer 1

1.) observation that illustrates the law of conservation of mass,

when 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced.(here mass is conserved)

2.) balanced chemical equation,

2Mg(s) + O2(g) = 2MgO(s)
