Question

Rahini took a piece of burning charcoal and collected the gas evolved in a test tube. how will she find the nature of the gas? write the word equations for all the reactions involved in this process.

Answer 1

when charcoal is burnt which is a type of carbon reacts atmospheric oxygen and forms co2.when co2 is passed through lime water it turns into milky white. hope this answer is useful to u

Answer 2

th the gas evolved is CO2 it can be tested by passing it through lime water it will turn the limewater milky due to the formation of CaCO3(calcium carbonate)
reactions----
Charcol+heat---->CO2+H2O
CO2+Ca(OH)2------>CaCO3+H2O
