1. The problem statement, all variables and given/known data "The following reaction is a metathesis reaction. Please predict the products from the given reactants and label the driving force." 2. Relevant equations MgO + HI -> ? [edited] 3. The attempt at a solution MgO(aq) + HI(aq) -> MgI2(aq) + H2O(l) MgO being soluble because of the hydroiodic acid. This makes the driving force water.
