Quiz Answer Key and Fun Facts

1. What substance goes milky/cloudy when you bubble carbon dioxide into it?

Answer: Lime water

This is a good test for carbon dioxide. Another good test is to put a lighted splint into a test tube of suspected C02 (carbon dioxide) and if the splint goes out the jar probably contains CO2. (This is a reason why CO2 is used in most fire extinguishers.)

2. Why is Hydrogen (the lightest element in the Periodic Table) not used in most balloons/airships?

Answer: It is flammable

A good test for Hydrogen is to put a lighted splint into a jar of suspected Hydrogen and see if it burns with a 'pop'. If it does, the gas could be Hydrogen.

3. What colour flame does Lithium have when it is lit?

Answer: crimson

Lithium is a very reactive metal. It is in Group 1 of the Periodic Table. See if you can experience the experiment mentioned in the question. The flame is very nice to look at.

4. What element is graphite made up of?

Answer: carbon

Graphite is found in most pencils. The reason it is used in pencils is because the layers of atoms are held together by weak 'Van der Waals' forces and these can be overcome easily. This enables graphite to make a mark on the paper.

5. What is the correct name for the compound common salt, and what kind of compound is it?

Answer: sodium chloride and an ionic compound.

Too much sodium chloride in your diet can be dangerous.

6. If iron and hydrochloric acid reacted, what would you get?

Answer: iron chloride and hydrogen

When a metal and an acid react you get a salt and hydrogen.

7. What chemical is made during 'The Haber Process'?

Answer: ammonia

Ammonia is very useful. It can be used to make fertilisers such as ammonium sulphate.

8. When is an oxygen molecule formed?

Answer: when two oxygen atoms bond together.

This type of bonding is called covalent bonding.

9. How many Hydrogen atoms are present in a methane molecule?

Answer: 4

Methane also consists of carbon atoms.

10. What colour flame is produced when magnesium burns in air? Also what is the compound you are left with?

Answer: a brilliant white flame, and magnesium oxide

When you are burning magnesium you have to be careful not to look directly at it as the flame can harm your eyes.
