What is the percentage Of Ag ion remaining in solution when 25.0 ml of 0115 M AgNo3 are added to 37.0 ml of 0.108 M K2CrO4? The precipitate, if it forms is Ag2CrO4, with a ksp= 2.0e-12. And how many grams of silver chromate precipitates, if it forms?
The reaction of methane and water is a way to prepare hydrogen according to CH4 (g) + H2O = Co2 (g) + H2 (g) a) If 995 g of CH4 reacts with 2510 g of water, how many moles of reactants and products are there when the reaction is finished
The equilibrium constant expression for the reaction 2BrF5(g) Br2(g) + 5F2(g) is A) Kc = [Br2] [F2] / [BrF5] D) Kc = [BrF5]2 / [Br2][F2]5 B) Kc = [Br2] [F2]5 / [BrF5]2 E) Kc = 2[BrF5]2 / ([Br2] × 5[F2]5) C) Kc = [Br2] [F2]2 / [BrF5]5
