Question

What is the balanced form of the chemical equation shown below?

Ny(o) + H2(o) - NH (O)
O A N (0) + Holo) - 2NH3(g)
O g
B. N2(o) + H2(g) - 2NH()
O (+
C. N2(o) + 3H2(o) - 2NH3(g)
O D. Ng(9) + H2(9) - NH (9)

Answer 1

c

nitrogen gas + hydrogen gas produces ammonia

N2( g)+ H2(g)=NH3( g)

hydrogen valency= 1, nitrogen =3 .Exchange them= NH3

balance

put 2 in front of NH3 to make nitrogen 2 .Them hydrogen is now 6,add3 to hydrogen to make them balance.

N2+3H2=2NH3
