What a Fizzer
Chemical Equations
Acid + Metal = Salt and Hydrogen
Hydrochloric Acid + magnesium -> magnesium chloride + Hydrogen
Acid + Carbonate = Salt + Carbon dioxide + water
Hydrochloric Acid + magnesium carbonate + carbon dioxide + Water
Acid + Base = Salt and Water (neutralisation)
Hydrochloric Acid + sodium Hydroxide -> sodium chloride + Water
Hydrochloric acid + anything equals a Chloride
Sulfuric acids equals a sulfate
Nitric Acids equals a Nitrate
