Balance:<br>n² + h² ➡️ nh³ <br>​
seropon [69]

Answer:

N₂ +  3H₂    →       2NH₃

Explanation:

Chemical equation:

N₂ +  H₂    →       NH₃

Balanced chemical equation:

N₂ +  3H₂    →       2NH₃

Step 1:

N₂ +  H₂    →       NH₃

left hand side:                       Right hand side

N =  2                                     N = 1

H = 2                                      H = 3

Step 2:

N₂ +  3H₂    →       NH₃

left hand side:                       Right hand side

N =  2                                     N = 1

H = 6                                      H = 3

Step 3:

N₂ +  3H₂    →       2NH₃

left hand side:                       Right hand side

N =  2                                     N = 2

H = 6                                      H = 6
