Answer» Sample of carbon dioxide taken from any source will always have carbon and oxygen in the RATIO `1:2`. Carbon forms two oxides namely `CO_(2)` and CO, where masses of oxygen which combine with fixed mass of carbon are in the SIMPLE ratio `2:1`. When magnesium burns in oxygen , the amount of magnesium taken for the reaction is equal to the amount of magnesium in magnesium OXIDE formed. At constant temperature and pressure 200 mL of hydrogen will combine with 100 mL oxygen to produce 200 mL of water vapour. Solution :The element carbon, combines with oxygen to form two compounds, carbon dioxide and carbon MONOXIDE. In `CO_(2)`, 12 parts by mass ofcarbon mix with 32 parts by mass of oxygen while in CO, 12 parts bymass of carbon combine with 16 parts by mass of oxygen. Thus, the masses of oxygen combine with a fixed mass of carbon in CO and `CO_(2)` are 16 and 32 respectively these masses of oxygen bear simple ratio of `16:32`or `1:2` to each other. This is an example of law of MULTIPLE proportion.
