Answer 2

Correct Question ::

Balanced the following equation :-

Mg ( s ) + N₂ ( g ) → Mg₃N₂ ( s )

Answer ::

The balanced equation is :- 3Mg ( s ) + N₂ ( g ) → Mg₃N₂ ( s )

Explanation ::

Step 1: The given following equation is,

Mg + N₂ → Mg₃N₂

So, here,

At left hand side, we have

• Magnesium ( Mg ) = 1
• Nitrogen ( n ) = 2

At right hand side, we have

• Magnesium ( Mg ) = 3
• Nitrogen ( n ) = 2

And here, at left hand side, magnesium is not balanced.

Step 2: To balance magnesium we need to set the coefficient 3 before Mg on the left hand side.

So, now the equation came,

3Mg + N₂ → Mg₃N₂

At the left hand side, we have

• Magnesium ( Mg ) = 3
• Nitrogen ( n ) = 2

At right hand side, we have

• Magnesium ( Mg ) = 3
• Nitrogen ( n ) = 2

Hence, the whole equation is balanced.

3Mg + N₂ → Mg₃N₂

[ Left hand side = Right hand side ]

Thus, the equation is balanced.

More Information

• Balancing of chemical equation is based upon law of conservation of mass.
• The simplest method of balancing a chemical equation is hit and trial method.
• The chemical equation in which number of atoms of each element are equal on both left hand side and right hand side of the equation is called a balanced equation.
