Question

For which of the following $H_{2}(g) + \frac{1}{2}O_{2}(g) \rightarrow H_{2}O(l);\Delta H = - 286kJ$

• A. $C_{2}H_{2}(g) + 2\frac{1}{2}O_{2}(g) \rightarrow 2CO_{2}(g) + H_{2}O(l);\Delta H = - 1301kJ$ ⇌ $- 1802kJ$
• B. $+ 1802kJ$ ⇌ $- 800kJ$
• C. $+ 228kJ$ ⇌ $\frac{1}{2}H_{2} + \frac{1}{2}Cl_{2} \rightarrow HCl$
• D. $HCl$ ⇌ $NH_{4}OH$

Answer 1

Answer: (C)

$+ 228kJ$ ⇌ $\frac{1}{2}H_{2} + \frac{1}{2}Cl_{2} \rightarrow HCl$

Answer 2

$NH_{4}OH$ for this reaction so, $CH_{3}COOH$.
