Bath salts such as epsom contain hydrate salts such as mgso 4 ·7h 2 o (magnesium sulfate heptahydrate). when heated, water is released as vapor and anhydrous mgso 4 remains. determine how many moles of vapor are released when 15.5 g of mgso 4 ·7h 2 o are heated. hint: include h 2 o when calculating the molar mass.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
