Q.1
What would be the salt produced in the reaction of iron and hydrochloric acid?
  • Iron hydrochloride
  • Iron chloride
  • Chloro iron
  • Iron chlorate
Q.2
Which of the following combinations of chemicals is likely to be the most exothermic (gives out the most energy) when mixed together?
  • Iron and aluminum oxide
  • Magnesium and aluminum oxide
  • Zinc and copper sulfate solution
  • Magnesium and silver nitrate solution
Q.3
Which of the following reactions does not produce hydrogen gas?
  • Silver and citric acid
  • Zinc and hydrochloric acid
  • Magnesium and nitric acid
  • Iron filings and sulfuric acid
Q.4
Why are ionic compounds formed when a metal reacts with a non-metal?
  • One or more electrons are transferred from the metal to the non-metal
  • One or more electrons are transferred from the non-metal to the metal
  • All of the electrons are transferred from the metal to the non-metal
  • They share a pair of electrons
Q.5
Which of the following metals is displaced from its ore by using carbon?
  • Iron
  • Sodium
  • Gold
  • Magnesium
Q.6
What would you see if you added lithium to water?
  • An explosion
  • The metal fizzes and burns with a purple flame
  • The metal fizzes, forms a molten ball and moves around the surface of the water
  • The metal fizzes and moves around but doesn't melt
Q.7
One way of producing copper would be to add which of the following metals to copper sulfate solution?
  • Platinum
  • Gold
  • Carbon
  • Iron
Q.8
Which of the following would be produced when lithium carbonate reacts with nitric acid?
  • Hydrogen
  • Water
  • Lithium nitrate
  • Carbon dioxide
Q.9
What would you see if you added potassium to water?
  • An explosion
  • The metal fizzes and burns with a purple flame.
  • The metal fizzes, forms a molten ball and moves around the surface of the water
  • The metal fizzes and moves around but doesn't melt
Q.10
If you drop a piece of cleaned magnesium ribbon into a solution of silver nitrate, the magnesium becomes coated with a gray substance. What is the explanation for this?
  • Magnesium is more reactive than silver and displaces the silver
  • Magnesium is less reactive than silver and displaces the silver
  • The magnesium reacts with the nitrate and is coated in magnesium nitrate
  • Silver in silver nitrate is actually more reactive than magnesuim ribbon so the magnesium corrodes
