Question

Magnesium ribbon is burnt in a jar containing nitrogen gas when a white powder of magnesium nitride is obtained. Give a balanced chemical equation for this.

Answer 1

Magnesium ribbon is burnt in a jar containing nitrogen gas, which gives a white powder of magnesium nitride.

we know,

symbol of magnesium = Mg

chemical formula of nitrogen gas = N2

chemical formula of magnesium nitride = Mg3N2

so, skeleton chemical reaction will be ...

$Mg+N_2\rightarrow Mg_3N_2$

see ,left side present only one magnesium atom while right side three magnesium atoms.

To balance chemical, just multiply 3 with magnesium.

e.g., $3Mg+N_2\rightarrow Mg_3N_2$ This is balanced chemical equation.

Answer 2

Answer:

Explanation:

LHS- Magnessium ribon =mg, Nitrogen gas =N3,. RHs -white powder of Magnessium nitrade is produce = Mg3N2
