What is the gibbs free energy at 298k for c(s) + 2h2((g) . delta h=-74.85 kj/mol, delta s is -.08084 kj/ mol
is the reaction spontaneous at 298k (room temp)? when nacl dissolves in water is endothermic butvwhen water is added it dissolves without added energy over a range of temperature why is this?

In the lab, ammonia was mixed with water to form ammonium hydroxide. what is/are the reactant(s)? o water and ammonia o ammonia o ammonium hydroxide need

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
