300 ml of a 0.694 m hcl aqueous solution is mixed with 300 ml of 0.347 m ba(oh)2 aqueous solution in a coffee-cup calorimeter. both the solutions have an initial temperature of 28.7 °c. calculate the final temperature of the resulting solution, given the following information: h+(aq) + oh- (aq) → h2o(ℓ) δhrxn = -56.2 kj/mol assume that volumes can be added, that the density of the solution is the same as that of water (1.00 g/ml), and the specific heat of the solution is the same as that for pure water, 4.184 j/(gk).

Predict the products of the following acid-base reactions, and predict whether the equilibrium lies to the left or to the right of the reaction arrow.part ao2-(aq)+h2o(l)< => express your answer as part of a chemical equation. identify all of the phases in your answer.o2-(aq)+h2o(l) < => oh-(aq)+oh-(aq)part bpredict whether the equilibrium lies to the left or to the right of the equation in previous part.h2o is a stronger acid than oh–, so the equilibrium lies to the right.h2o is a weaker acid than oh–, so the equilibrium lies to the left.h2o is a stronger acid than oh–, so the equilibrium lies to the left.h2o is a weaker acid than oh–, so the equilibrium lies to the right.part cch3cooh(aq)+hs?
