Question

What are combination reactions? Give examples.

Answer 1

In a combination reaction, two or more reactants combine to form a single product. The general representation of this reaction is:

$A+B\to C$
The following reactions are examples of combination reactions:

$8\mathrm{Fe}\left(s\right)+S_8\left(s\right)\to 8\mathrm{FeS}\left(s\right)\mathrm{MgO}\left(s\right)+{\mathrm{CO}}_2\left(g\right)\to {\mathrm{MgCO}}_3\left(s\right)$
