• CaCN₃

• Ca₂CN

Answer 1

The product obtained as a result of a reaction of nitrogen with CaC₂ is Ca(CN)₂.

Explanation:

When nitrogen gas reacts with calcium carbide (CaC₂), the product formed is calcium cyanamide, which has the formula Ca(CN)₂. This compound is an important fertiliser and is produced by the direct combination of nitrogen with CaC₂ at high temperature. It is used in agriculture to provide nitrogen to plants.
