**Chemical Reaction Analysis**

Consider the following chemical reaction:

\[ 2 \, \text{CH}_3\text{OH}(g) \rightarrow 2 \, \text{CH}_4(g) + \text{O}_2(g) \]

\[\Delta H = +252.8 \, \text{kJ}\]

**Question:** Is this reaction exothermic or endothermic?

- [ ] Exothermic
- [x] Endothermic

**Explanation:** Since the enthalpy change ($\Delta H$) is positive, the reaction is endothermic, meaning it absorbs heat from the surroundings.

**Calculation Task:** Calculate the amount of heat transferred when 24.16 g of $\text{CH}_3\text{OH}$ is decomposed by this reaction at constant pressure.

Please note: The solution involves using the molar mass of $\text{CH}_3\text{OH}$ and applying stoichiometry to find the heat transferred based on the given $\Delta H$.

Calculate the amount of heat transferred when 24.0 g of CH₃OH is decomposed by this reaction at constant pressure.

\[ \text{amount of heat transferred:} \_\_\_\_ \text{kJ} \]

For a given sample of CH₃OH, the enthalpy change during the reaction is 537.8 kJ. What mass of methane gas is produced?

\[ \text{mass of CH₄ produced:} \_\_\_\_ \text{g} \]
