What acid can I use to prepare magnesium sulfate?

Which acid can I use to prepare calcium chloride?

Can I use sodium metal to prepare sodium chloride?

• Yes, sodium is a reactive metal

• No, sodium is unreactive

• No, sodium is a very reactive metal and it will be dangerous

• Yes, sodium is insoluble in water

Which of these can be used to prepare copper (II) sulfate?

• copper metal

• copper (II) chloride solution

• copper (II) nitrate solution

When making calcium nitrate solution, why do we add calcium carbonate in excess to nitric acid?

• to ensure all the acid is used up

• to ensure a lot of calcium nitrate is formed

• to ensure there is no excess calcium carbonate

• because calcium carbonate is soluble
