Answer:
B
Solution:
Statement-2 correctly defines Gay-Lussac's Law. The reaction is . By Gay-Lussac's Law, 2 volumes of H₂ react with 1 volume of O₂ to yield 2 volumes of H₂O. Given 10 mL H₂ and 5 mL O₂, the 2:1 ratio is met. Thus, 10 mL H₂O is formed. Both statements are true, and Statement-2 explains Statement-1.
