Question

What is a combination reaction? Explain with an example.

Answer 1

Part 1: Definition of combination/synthesis reaction:

• The combination or synthesis reaction occurs when two or more elements or compounds combine chemically to form a new single product.
• The general representation for this reaction is: $\mathrm{X}+\mathrm{Y}\to \mathrm{XY}$

Part 2: Example of combination/synthesis reaction:

• Nitrogen and hydrogen combine together to form ammonia.
• $\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{3{\mathrm{H}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Ammonia}}{2{\mathrm{NH}}_3\left(\mathrm{g}\right)}$
