Magnesium oxide react with hydrogen chloride MgO + 2 HCl → MgCl 2 + H 2 O [ Check the balance ] Magnesium oxide react with hydrogen chloride to produce magnesium chloride and water. MgO (s) + 2 HCl (aq) → MgCl 2 (aq) + H 2 O (l) Here is the second reaction that you will perform in the calorimeter. As before, magnesium chloride will remain in solution as solvated ions. Reaction of Magnesium Oxide with Hydrochloric Acid? All the oxides and hydroxides of metals are basic in nature. Using these terms we obtain: Wat happens when you mix the two of them in a calorimeter? For the NaOH and HCl reaction, the specific heat of the solution, c, is 4.025 J/(g°C) while for the Mg and MgO reactions with HCl, c is equal to 3.862 J/(g°C).

MgO is a metal oxide, which is a type of basis oxide, and HCl is an acid. The MgO is a powder and the HCl is in liquid form… Reaction stoichiometry: Limiting reagent: Compound: Coefficient: Molar Mass: Moles: Weight: HCl: 2: 36.46094: MgO: 1: 40.3044: MgCl 2: 1: 95.211: H 2 O: 1: 18.01528 : Units: molar mass - g/mol, weight - g.

When acids and bases react, they form a salt ({eq}MgCl_2{/eq}) and water ({eq}H_2O{/eq}).
