Question

Укажите валентность металлов а) KON б) Ba(OH)2 в) Mg(OH)2 г) Fe(OH)3

Answer 1

валентность металлов

а) KOH    I

б) Ba(OH)2    II

в) Mg(OH)2    II

г) Fe(OH)3      III

Answer 2

Valency of Metals in Compounds

a) KON: The valency of potassium (K) is 1, oxygen (O) is 2, and nitrogen (N) is 3. Therefore, the valency of K in KON is 1. b) Ba(OH)2: The valency of barium (Ba) is 2, and the valency of hydroxide (OH) is 1. Therefore, the valency of Ba in Ba(OH)2 is 2. c) Mg(OH)2: The valency of magnesium (Mg) is 2, and the valency of hydroxide (OH) is 1. Therefore, the valency of Mg in Mg(OH)2 is 2. d) Fe(OH)3: The valency of iron (Fe) is 3, and the valency of hydroxide (OH) is 1. Therefore, the valency of Fe in Fe(OH)3 is 3. I hope this helps!
