Consider the following reaction: ch4(g) + 2 h2s(g) ⇌ cs2(g) + 4 h2(g) a reaction mixture initially contains 0.50 m ch4 and 0.75 m h2s. if the equilibrium concentration of h2 is 0.44 m, find the equilibrium constant (kc) for the reaction.

Which describes fat? a: a carbohydrate that produces energy b: a nucleic acid that directs cell function c: a lipid that stores energy d: a protein that speeds up a chemical reaction

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
