In the reaction of magnesium metal with hydrochloric acid, how do you determine when the magnesium metal has reacted completely? Select all that apply. Mg (s) + 2 H* (aq) → Mg²+ (aq) + H2 (g) Select one or more: All of the water has evaporated. The dilute Hcl is gone. The magnesium metal is gone. Gas bubbles are no longer produced.

Directions: Balance the chemical equations and identify the type of chemical reaction for each of thefollowing items11. NH3 + H2SO4 → (NH4)2SO412. CuSO4 + Fe → Fe2(SO4)3 + Cu13. C2H6 + O2 → CO2 + H2O14. Al(ClO3)3 + MgCrO4 → Al2(CrO4)3 + Mg(ClO3)215. C3H5N3O9 → CO2 + N2 + O2 + H2O
