Magnesium wire continues to burn in the atmosphere of `CO_2` though `C)_2` is not a supproter fo combusion because

Options

A. Mg acts as an oxidising agent
B. Mtg has high ionization energy
C. Mg acts as a reducing agent and removes oxygen from `CO_2`
D. All of the above

Answer

C

Explanation

Mg is more electropositive than carbon and has more affinity for `O_2` than that of C. As such the enthalpy of formation of MgO is more than of `CO_2`, therefore, Mg continues to burn in `CO_2`
`CO_2+2Mgto2MgO+C`
