The solubility of silver bromide can be increased by dissolving it in a solution containing the thiosulfate anion. AgBr(s) Ag+ (aq) + Br- (aq) K1 = 7.7 x 10-13 Ag+(aq) + 2S2O32- (aq) Ag(S2O3)23- (aq) K2 = 4.7 x 1013 What is the value of the equilibrium constant for the overall reaction? AgBr(s) + 2S2O32-(aq) Ag(S2O3)23-(aq) + Br-(aq)

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
