Question

Hola, pueden ayudar a balancear NaOH + H 2 SO 4 Na 2 SO 4 + H 2 O y Fe + Cl 2 FeCl 2, por metodo de tanteo, por favor. :((

Answer 1

Explicación:

(a) NaOH + (b) H2SO4___ (c) Na2SO4 +(d) H2O

a = 2c

b = c

a + 4b = 4c +d

a + 2b = 2d

c = 1

b = 1

a = 2

d = 2

(a) Fe + (b) Cl2 ___ (c) FeCl2

a = c

2b = 2c

a = 1

c = 1

b = 1
