  • What is the term for the reaction between an acid and an alkali?
    a neutralisation reaction
  • What does the reactivity series order?
    metals by how readily they react with other substances
  • What is the product when magnesium reacts with sulfuric acid?
    magnesium sulfate and hydrogen
  • What is the general equation for the reaction of a metal with an acid?
    metal + acid → salt + hydrogen
  • What is the product when zinc reacts with hydrochloric acid?
    zinc chloride and hydrogen
  • ------------------- + Hydrochloric acid —> Magnesium chloride + hydrogen
    Magnesium
  • Describe how the reactivity of a metal affects its reaction with an acid.
    very reactive metals such as potassium, sodium, and calcium react violently with acids, producing lots of gas bubbles, fire or even explosion.
  • How can you tell if a metal is reacting with an acid?
    gas bubbles are produced
  • What happens when unreactive metals like copper, silver, gold are placed in acids?
    no change is observed
  • Zinc + -------------------- —> Zinc chloride + hydrogen
    Hydrochloric acid
  • What happens in a displacement reaction?
    a more reactive element displaces a less reactive element from its compound
  • What is the reaction between an acid and an alkali called?
    a neutralisation reaction
  • What is the term for the process when one metal takes the place of another in a compound?
    displacement reaction
