**Problem Description:**

Calculate the entropy change when a gas condenses at its boiling point.

**Given:**

Calculate the entropy change when 2.47 moles of methane condenses at its boiling point of -162°C. The heat of vaporization of CH₄ is 8.2 kJ/mol.

**Solution:**

ΔS = ____ J/K

**Interactive Elements:**

- **Show Approach** link

Predict the sign and calculate ΔS° for a reaction.

**Consider the reaction**

\[2\text{CO}(g) + 2\text{NO}(g) \rightarrow 2\text{CO}_2(g) + \text{N}_2(g)\]

Based upon the stoichiometry of the reaction, the sign of ΔS°\(_{\text{rxn}}\) should be __.

Using standard thermodynamic data (*in the Chemistry References*), calculate ΔS°\(_{\text{rxn}}\) at 25°C.

ΔS°\(_{\text{rxn}}\) = __ J/K·mol

Based on a grade 11 chemistry student, answer the following question based on the provided table:Part B: Other Cases EmergeRead Case File 3. Based on these new cases, it now seems clear that people are being poisoned by something in the Tylenol. Fast-Acting PoisonsWhatever the poison is, it is very fast acting as victims collapsed within minutes of taking the pills. After some research, and based on your love of Agatha Christie novels, you find five common poisons that work quickly and can cause death within a few hours – aconite, coniine, cyanide, nicotine, strychnine. Use the information contained in table 6 to determine the empirical formula, molecular formula, and fatal volume for the two poisons not completed in the table.
could you space it out better with better labels?
