When ammonia gas is passed into hydrochloric acid, the resulting product is:
Ammonium hydroxide
Ammonium chloride
Ammonium sulfate
Ammonium nitrate
When hydrochloric acid reacts with a metal X, the product is the corresponding chloride. If X is magnesium, what is the balanced chemical equation for the reaction?
HCl + Mg → MgCl2 + H2
2HCl + Mg → MgCl2 + H2
HCl + Mg → MgCl + H2
HCl + Mg → Mg2Cl + H2
In the reaction between sulfuric acid and potassium hydroxide, the balanced equation is:
