When 12 grams of carbon react with 32 grams of oxygen, the compound carbon dioxide (a greenhouse gas) is formed. what is true about other combinations of carbon and oxygen ?

Option C = 6 of carbon react with 16 g of oxygen.

Explanation:

In given question it is stated that 12 g  of carbon react with 32 g of oxygen to produce carbon dioxide. The other combination option c is also true because in this, the quantity of both reactant is just half from the given quantity. Which means that if 100 % product is obtained from the 12 g of carbon and 32 g of oxygen then by taking the half amount of reactant the product will be half i.e 50% .

This combination is true because the ratio of both reactant are justified.

Carbon 12g + Oxygen 32g → carbon dioxide

           C : O     1  : 2.6

Option C:

Carbon ( 12/2 =6g ) + Oxygen (32/2 = 16g) → Carbon dioxide

           C : O     1  : 2.6
