Question

Burning of charcoal is a/an:1 exothermic reaction 2 combination reaction 3oxidation reaction 4 all the above

Answer 1

The correct option is 4 all of the above.

• The reaction of the burning of charcoal is-
• $C+O_2\rightarrow CO_2$
• In this reaction heat is evolved so, this reaction is exothermic.
• In this reaction carbon and oxygen combines to give carbon dioxide so, it is a combination reaction
• Again in this reaction the oxidation state of carbon changes to +4 from 0. So, it is an oxidation reaction.
