Detailed explanation-2: -Consider the elements carbon and oxygen. Combined in one way, they form the familiar compound carbon dioxide. In every sample of carbon dioxide, there are 32.0g of oxygen present for every 12.0g of carbon.
Detailed explanation-3: -Carbon and oxygen combine to form two oxides, carbon monoxide and carbon dioxide in which the ratio of the weights of carbon and oxygen is respectively 12:16 and 12:32.
Detailed explanation-4: -C Carbon + O 2 Oxygen → CO 2 carbon dioxide.
