To test the presence of CO2: pass the evolved gas to lime water. Lime water turns milky. Because it forms calcium carbonate
To test t he presence of O2: a glowing splinter will relight. Because O2 supports combustion.
To test the presence of MnO2: it reacts with sulphuric acid and forms a pink solution (if it is pure MnO2)
