Answer:a]Hydrogen peroxide is unstable and very reactive. It's vapours are explosive in natureat normal temperatures and pressures. ... It should be kept in non reactive containers.
b]Anhydrous BaO2 cannot be used to prepare H2O2 by reacting with acid . The white precipitate of BaSO4 is removed by filtration leaving behind a dilute solution (5%) of H2O2.
c]It is because hydrogen is a highly combustible and it reacts explosively when it comes in contact with air. And hence as a result, storing of the hydrogen gas is difficult and is dangerous at the same time. So, even though hydrogen has the highest calorific value, it is not used as a domestic fuel.
