Question

Enthalpy $CO_{2}(g)$ is equal to.

• A. Internal energy (E)
• B. Product of pressure (P) and volume (V) of gas
• C. Internal energy (E)+PV
• D. Work (W) done by a system

Answer 1

Answer: (C)

Internal energy (E)+PV

Answer 2

Enthalpy $\frac{1}{2}H_{2} + \frac{1}{2}Cl_{2} \rightarrow HCl$ is defined as the sum of internal energy $HCl$, $NH_{4}OH$.
