In the following questions a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below each question.

Assertion (A) : Combustion of 16 g of methane gives 18 g of water.


Reason (R) : In the combustion of methane, water is one of the products.



Combustion of methane is given by the reaction


CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)


If 1 mol of methane is combusted completely, it will give 2 mol of H2O. Hence, 16g of methane on combustion gives 36g of H2O not 18g.


So, from the above reaction we can conclude that H2O is a product.
