Chapter 16: Q146CP (page 704)

You and a friend each synthesize a compound with the formula XeCl₂F₂ . Your compound is a liquid, and your friend’s compound is a gas (at the same conditions of temperature and pressure). Explain how the two compounds with the same formulas can exist in different phases at the same conditions of pressure and temperature.

Short Answer

Expert verified

The two compounds with the same formulas can exist in different phases at the same pressure and temperature conditions because the compounds are isomers.

Step by step solution

01

Isomers

The compounds that have the same chemical formulas and different physical and chemical properties are known as isomers.

02

Step 2: Explanation

At the same conditions of pressure and temperature, the compound XeCl₂F₂ exists in two phases, which means the two phases are in equilibrium at a particular pressure and temperature.

A $0.250 - g$ chunk of sodium metal is cautiously dropped into a mixture of $50.0 g$ of water and $50.0 g$ of ice, both at $0 ° C$ . The reaction is

$2 Na (s) + 2 H_{2} O (l) \to 2 NaOH (aq) + H_{2} (g) ΔH = - 368 kJ$

Will the ice melt? Assuming the final mixture has a specific heat capacity of $4.18 {Jg}^{- 1} {}^{o}C^{- 1},$ calculate the final temperature.
