What is the correct equilibrium constant expression for the following heterogeneous equilibrium? 4hcl (g) + o2 (g) ⇄ 2h2o (l) + 2cl2 (g) view available hint(s) what is the correct equilibrium constant expression for the following heterogeneous equilibrium?
4hcl (g) + o2 (g) ⇄ 2h2o (l) + 2cl2 (g)
kc=[cl2]/[hcl][o2] kc=[hcl]4[o2]/[cl2]2

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
