In the following question, a Statement of Assertion (A) is given follo...
Explanation:

  • The Assertion(A) states that 10 vol. HO means that 1 mL of HO solution at NTP gives 10 mL of O gas.

  • The Reason(R) for this is that HO decomposes to give water and O.

  • Both Assertion and Reason are true and Reason is the correct explanation of assertion.

  • When HO decomposes, it gives water and O gas. The volume of gas produced is 10 times the volume of the HO solution used.

  • This can be represented as: 2HO -> 2H2O + O2

  • So, according to Avogadro's Law, one mole of any gas at the same temperature and pressure occupies the same volume. Therefore, one mole of O2 gas occupies 22.4 L at NTP.

  • Now, to calculate the volume of O2 gas produced from 1 mL of HO solution, we need to find the number of moles of O2 gas produced.

  • The molar mass of HO is 34 g/mol. So, 1 mL of 10 vol. HO solution contains 0.34 g of HO.

  • Using the balanced chemical equation, we can see that 2 moles of HO produce 1 mole of O2 gas.

  • So, 0.34 g of HO will produce (1/2) * (0.34/34) = 0.005 moles of O2 gas.

  • Therefore, the volume of O2 gas produced from 1 mL of HO solution will be (0.005 * 22.4) = 0.112 L or 112 mL.

  • So, the Assertion is correct and the Reason is the correct explanation for it.

  • Hence, the correct answer is option (A).
