1. The problem statement, all variables and given/known data Hi,there is a question from my textbook: Name FOUR substances commonly found in the laboratory to prepare magnesium sulphate by reacting with dilute sulphuric acid. 2. Relevant equations 3. The attempt at a solution Here is my answer: Mg(OH)2,MgO,MgCO3,Mg(HCO3)2 Here is the model answer: Mg,Mg(OH)2,MgO,MgCO3 Mg(HCO3)2 react with H2SO4 to give MgSO4: Mg(HCO3)2 (aq) + H2SO4 (aq) --> MgSO4 (aq) + CO2(g) + H2O(l) Is it possible for me to write Mg(HCO3)2?If not,please explain briefly. THX a lot.
