When lithium perchlorate,liClO4 is heated, a gas is giving off, leaving a white residue. This gas is colourless but can rekindle a glowing splint. The residue dissolves completely in water and when a silver nitrate is added to the solution, a white precipitate is formed.
a) what is the name and the formula of the gas?
b) what is the name and the formula of the residue?
c) Write down the chemical equation for the thermal decomposition of LiClO4?
d) Write the equation for the reaction of the aqueous solution with silver nitrate.
e) What mass of residue is obtained if 2.13g of lithium perchlorate are heated to constant mass?
