Answer 1

HEY MATE !!!

5) yes

6) We can test the gas using the LIME WATER TEST if the lime water turns milky when gas is passed through it, it is confirmed that the gas is carbon dioxide or even THE POP SOUND TEST can be done

7) Flame test

8) Reaction of hydrogen with air. Hydrogen is a colourless gas, that is lighter than air. Mixtures of hydrogen gas and air do not react unless ignited with a flame or spark, in which case the result is a fire or explosion with a characteristic reddish flame whose only products are water, H2O.

9) decomposition reaction

10) oxidation reaction (I think so)

HOPE YOU'VE FOUND IT IMFORMATIVE !!!
