2) What is the effect of acid on the following substances and what gas is produced?
Copper, Zinc, Calcium Hydroxide, copper(II) carbonate
1) Copper does not burn, but copper wire becomes coated with a black-coloured substance. In the presence of air copper forms its oixide.
Copper(II) carbonate decomposes to copper(II) oxide and carbon dioxide gas is produced.
2) Copper does not react with ...
The effects of heat and acid on copper, zinc, calcium hydroxide, and copper(II) carbonate are discussed. A discussion of whether gas would be produced if these elements were heat or covered in acid is in the solution. The solution is 165 words.
