Answer 1

CaCl2 + KNO3 → Ca (NO3)2 + KCl

• Resolucion:

1 = Ca = 1

2 = Cl = 1

1 = K = 1

1 = N = 2

3 = O = 6

CaCl2 + 2KNO3 → Ca (NO3)2 + 2KCl

1 = Ca = 1

2 = Cl = 2

2 = N = 2

2 = K = 2

6 = O = 6

• Orden: 1, 2, 1, 2
• Tipo: Doble sustitucion

Al (OH)3 + H2SO4 → Al2 (SO4) 3 + H2O

• Resolucion:

1 = Al = 2

7 = O = 13

5 = H = 2

1 = S = 3

2Al (OH)3 + 3H2SO4 → Al2 (SO4) 3 + 6H2O

2 = Al = 2

18 = O = 18

12 = H = 12

3 = S = 3

• Orden: 2, 3, 1, 6
• Tipo: Doble sustitucion
