(a) Describe everything you expect to see when sodium is added to water containing universal indicator.
2. (a)
Describe the test and result for the gas produced in the
reaction between calcium and cold water. (b) give the symbol equation for
magnesium reacting with cold water.
3. (a) Describe what happens when magnesium is heated strongly in oxygen and
give equation. (b) when strongly heated in air, copper forms a black solid. What
is the solid?
4. What happens when the product of burning sodium is added to water containing universal indicator and named the product formed in water.
5. (a) Give three observations that could be made when magnesium reacts with sulphuric acid.
6. (a) What substances must be in contact with iron before it will rust?
7. (a) Give three observations that could be made after adding zinc to copper(II) sulphate solution.
. Copper(II) carbonate is heated with carbon powder. (i) The green carbonate powder changes to a black powder at first, and (ii) after further strong heating, reddish-brown bits of a metal are formed.
