WebWord Equation. Magnesium + Hydrogen Chloride = Magnesium Chloride + Dihydrogen. One mole of solid Magnesium [Mg] and two moles of aqueous Hydrogen Chloride [HCl] … WebMay 16, 2024 · Magnesium and hydrochloric acid react according to the chemical equation: Mg + 2HCl => MgCl2 + H2. This is an exothermic reaction, meaning that the forming of the bonds MgCl2 and H2 gives off heat. While not exactly correct to do so, I'll write "heat" as a product of the reaction to read: Mg + 2HCl => MgCl2 + H2 + heat sjz tax service barneveld ny
