Question

ejercicios: (método al tanteo)​

Answer 1

Respuesta:

1. $N_{2} + H_{2} + Br_{2} = NH_{2}Br$

  $N_{2} + 2H_{2} + Br_{2} = 2NH_{2}Br$

2. $Fe(OH)_{3} + HF = FeF_{3} + H_{2}O$

    $Fe(OH)_{3} + 3HF = FeF_{3} + 3H_{2}O$

3. $C + H_{2} + S = C_{10}H_{10}S$

    $10C + 5H_{2} + S = C_{10}H_{10}S$
