(a) Write an equation to show the action of strong heat on:
(i) potassium trioxonitrate (V):
(ii) sucrose.
(b) State two observations in respect of the reaction between granulated zinc and dilute tetraoxosulphate (VI) acid.
Explanation
(a)(i) 2KNO(_3) (to) 2KNO(_2) + O(_2)
(ii) C(_{12})H(_{22})O(_{11}) + 11H(_2)O
(b) Two observations include:
(i) gas is given off
(ii) The zinc disappears to form a colourless solution.
