Predict the reactions, if any, when the following hydrogen compounds are added to water, and explain your reasoning of why the reaction occur like that (explain the role of H in each case, is it bronsted-lowry acid or base? why?) a) HBr b) CaH2 c) CH4. d) H2S
Use the following reactions and their equilibrium constants to predict the equilibrium constant for the following reaction: 2 A (s) ?? 3 D (g) (1) A (s) ?? ½ B (g) + C(g) K1= 2.97 (2) 3D (g) ?? B (g) + 2 C (g) K2= 1.29
