Question

The following reaction is a/an –
$C\left(s\right)+O_2\left(g\right)\to C{O}_2\left(g\right)+Heat$

• A. Combination reaction
• B. Oxidation reaction
• C. Exothermic reaction
• D. All of the above

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Combination reaction

B

Oxidation reaction

C

Exothermic reaction

$C\left(s\right)+O_2\left(g\right)\to C{O}_2\left(g\right)+Heat$

This is a combination reaction because carbon and oxygen atoms combine to form a carbon dioxide molecule.
As an atom is reacting with oxygen, this is also an oxidation reaction.
It is also an exothermic reaction because heat and light are being released.
