Question

2HCl+ZnO=ZnCl2+H2O ионный вид

Answer 1

Молекулярное:

2HCI + ZnO -> ZnCl2 + H2O

Полное ионное:

2H(+)+2Cl(-) + ZnO -> Zn(2+)+2Cl(-) + H2O

Краткое ионное:

2H(+) + ZnO -> Zn(2+) + H2O

Answer 2

To write the ionic equation for the reaction between hydrochloric acid (HCl) and zinc oxide (ZnO) that produces zinc chloride (ZnCl2) and water (H2O), we first need to understand the dissociation of the compounds in water.

Hydrochloric acid (HCl) is a strong acid, so it fully dissociates into its constituent ions:

HCl (aq) → H+ (aq) + Cl- (aq)

Zinc oxide (ZnO) is a basic oxide, so it reacts with water to form zinc hydroxide:

ZnO (s) + H2O (l) → Zn(OH)2 (aq)

Zinc hydroxide then further dissociates into its constituent ions:

Zn(OH)2 (aq) → Zn2+ (aq) + 2OH- (aq)

Now, let's write the overall ionic equation for the reaction:

H+ (aq) + Cl- (aq) + ZnO (s) + 2OH- (aq) → Zn2+ (aq) + 2Cl- (aq) + H2O (l)

In the ionic equation, the spectator ions (Cl- and OH-) are canceled out, as they appear on both sides of the equation. The net ionic equation is as follows:

H+ (aq) + ZnO (s) → Zn2+ (aq) + H2O (l)
