D

Explanation:

1, 2, 2, 1

Shannon · Answer 2

D

Explanation:

Mg (OH) 2 (s) + HCl (aq) →H2O (l) + MgCl2 (aq)

Left Side

Mg = 1

O = 2

H = 3

Cl = 1

Right Side

Mg = 1

O = 1

H = 2

Cl = 2

Mg (OH) 2 (s) + 2HCl (aq) →2H2O (l) + MgCl2 (aq)

Left Side

Mg = 1

O = 2

H = 4

Cl = 2

Right Side

Mg = 1

O = 2

H = 4

Cl = 2

D) 1, 2, 2, 1
