Respuesta:
- Zn + HCl --> ZnCl2 + H2
1 = Zn = 1
1 = H = 2
1 = Cl = 2
RESPUESTA: Zn + 2HCl --> ZnCl2 + H2
1 = Zn = 1
2 = H = 2
2 = Cl = 2
- HCl + Ca (OH)2 --> CaCl2 + H2O
2 = H = 2
1 = Cl = 2
1 = Ca = 1
2 = O = 1
RESPUESTA: 2HCl + Ca (OH)2 --> CaCl2 + 2H2O
4 = H = 4
2 = Cl = 2
1 = Ca = 1
2 = O = 2
- Al2O3 + H2SO4 --> Al2 (SO4)3 + H2O
2 = Al = 2
7 = O = 13
2 = H = 2
1 = S = 3
RESPUESTA: Al2O3 + 3H2SO4 --> Al2 (SO4)3 + 3H2O
2 = Al = 2
15 = O = 15
6 = H = 6
3 = S = 3
- P + O2 --> P2O3
1 = P = 2
2 = O = 3
RESPUESTA: 4P + 3O2 --> 2P2O3
4 = P = 4
6 = O = 6
- Na + H2O --> NaOH + H2
1 = Na = 1
2 = H = 3
1 = O = 1
RESPUESTA: 2Na + 2H2O --> 2NaOH + H2
2 = Na = 2
4 = H = 4
2 = O = 2
- Zn + HCl --> ZnCl2 + H2
1 = Zn = 1
1 = H = 2
1 = Cl = 2
RESPUESTA: Zn + 2HCl --> ZnCl2 + H2
1 = Zn = 1
2 = H = 2
2 = Cl = 2
- HCl + Ca (OH)2 --> CaCl2 + H2O
3 = H = 2
1 = Cl =2
1 = Ca = 1
2 = O = 1
RESPUESTA: 2HCl + Ca (OH)2 --> CaCl2 + 2H2O
4 = H = 4
2 = Cl =2
1 = Ca = 1
2 = O = 2
- Al2O3 + H2SO4 --> Al2 (SO4)3 + H2O
2 = Al = 2
