You can identify hydrogen and carbon dioxide by lighting a wooden splint and putting it near the gasses. Since hydrogen is flammable, the flame will get bigger. Since carbon dioxide does not burn, it may get smaller or go out.
Manganese dioxide is a catalyst for the decomposition of hydrogen peroxide.
A gas as carbon dioxide is easily expanded by heating; hydrogen peroxide is decomposed.
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
Carbon dioxide form a milky suspension of calcium carbonate in calcium hydroxide; hydrogen doesn't react. But hydrogen react with oxygen when a flame exist.

carbon dioxide will extinguish a flaming splint, hydrogen will burn rapidly
Hydrogen gas is evolved when acids act on certain metals. For example, when hydrochloric acid acts on sodium, sodium chloride is formed as hydrogen gas escapes.
Hydrogen sulphide has the unpleasant smell of rotten eggs.
H2O2 is a common name for hydrogen dioxide
dioxide is di(two)oxide(oxygen). no hydrogen.
Is this HO2 for hydrogen dioxide, never heard of it in 'normal' life
Hydrogen dioxide is water and the oxidation numbers are +1 for each hydrogen and -2 for oxygen
hydrogen
No, hydrogen, oxygen and carbon dioxide have very different weights.
Manganese dioxide is a catalyst for the decomposition of hydrogen peroxide.
Yes manganese dioxide catalyzes the break down of hydrogen peroxide.
