When a black metal compound XO is heated with a colourless gas Y2, then metal X and another compound Y2O are formed. Metal X is red-brown in colour which does not react with dilute acids at all. Gas Y2 can be prepared by the action of a dilute acid on any active metal. The compound Y2O is a liquid at room temperature which can turn anhydrous copper sulphate blue.
(a) What do you think is metal X?
(b) What could be gas Y2?
(c) What is compound XO?
(d) What is compound Y2O?
(e) Write the chemical equation of the reaction which takes place on heating XO with Y2.
(f) What type of chemical reaction is illustrated in the above equation?
The colour of an aqueous solution of zinc sulphate as observed in the laboratory is:
(1) Green
(2) Yellow
(3) Blue
(4) Colourless
To show that zinc is a more active metal than copper, the correct procedure is to:
(1) add dilute nitric acid on strips of both the metals.
(2) observe transmission of heat through strips of zinc and copper.
(3) prepare solution of zinc sulphate and hang strip of copper into it.
(4) prepare solution of copper sulphate and hang strip of zinc into it.
What is observed after about 1 hour of adding the strips of copper and aluminium separately to the ferrous sulphate solution filled in two beakers? Name the reaction if any change in colour is noticed. Also, write a chemical equation for the reaction.
