Answer: The first precipitate formed is Barium Sulphate
Explanation:
This is because the reaction that takes place will be as follows:
K2SO4 + Ba (NO3)2 ------> BaSO4 + K2(NO3)2
And K2SO4 + Pb(NO3)2 -----> PbSO4 + K2(NO3)2
Considering the concentration of Barium Nitrate which is lower than that of Lead Nitrate it tends to attain equilibrium faster and the Barium salt or precipitate is formed....

See explanation
Explanation:
According to the kinetic molecular theory, the molecules that compose a gas are in constant random motion.
The temperature of a gas is a measure of the average kinetic energy of the gas molecules.
When the balloon was placed in a hot water bath, the balloon becomes larger because the gas inside the balloon expands. This is because, more kinetic energy is supplied to the molecules of the gas hence they spread out.
When the balloon is placed in cold water, the kinetic energy of the gas molecules in the balloon decreases as temperature decreases hence the balloon shrinks
