Current Question (ID: 7369)

Question:

$\text{Assertion (A):}$ $\text{The combustion of 16 g of methane gives 18 g of water.}$ $\text{Reason (R):}$ $\text{In the combustion of methane, water is one of the products.}$

Options:

1. $\text{Both (A) and (R) are True and (R) is the correct explanation of (A).}$
2. $\text{Both (A) and (R) are True but (R) is not the correct explanation of (A).}$
3. $\text{(A) is True but (R) is False.}$
4. $\text{(A) is False but (R) is True.}$

Solution:

$\text{Hint:}$ $\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}$ $\text{The combustion reaction of methane is as follows:}$ $\text{CH}_4$ $1 \text{ mol}$ $= 16\text{g} + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}$ $2 \text{ mol}$ $= 36\text{g}$ $\text{From the equation, it is clear that 1 mole or 16 g CH}_4 \text{ produces 2 mol or 36 g of H}_2\text{O}$ $\text{Thus, the Assertion is false but the reason is true because the amount of water is 36g, not 18g. Water is one of the products.}$
