Question

Saloni took a piece of burning charcoal and collected the gas evolved in a testa tube. (a) How will she find the nature of the gas ? (b) Write down word equations of all the reactions taking place in this process

Answer 1

charcoal reacts with oxygen to form carbon dioxide gas.
C +O2 = CO2
(carbon from (Oxygen) (Carbon dioxide)
charcoal)

Carbon dioxide reacts with water to form carbonic acid,which turns blue Litmus Paper Red

CO2 + H2O = H2CO3

Answer 2

charcoal reacts with oxygen to form carbon dioxide gas
c+o2= co2
(carbon)(oxygen) (carbon d) charcoal
carbon.d reacts with water to form
carbonic acid which turns blue litmus paper red
co2+ho2=h2co3
