Mn(s) + 2 CO(g)
O combination reaction
O decomposition reaction
O combustion reaction
O single-displacement reaction

Answer 1

Answer: The reaction,
`2C(s) + MnO_(2)(s) \rightarrow Mn(s) + 2CO(g)` is a single-displacement reaction.

Step-by-step explanation:

A chemical reaction in which one element of a compound is replaced by another element participating in the reaction.

For example,
`2C(s) + MnO_(2)(s) \rightarrow Mn(s) + 2CO(g)`

Here, the element manganese is replaced by carbon atom. As only one element gets replaced so, it is a single-displacement reaction.

Thus, we can conclude that
`2C(s) + MnO_(2)(s) \rightarrow Mn(s) + 2CO(g)` is a single-displacement reaction.
