Question

ZnO+HCl= Mg+H3PO4= Cu+HCl= BaO+HNO3= Fe2O3+HCl=

Answer 1

ZnO + 2 HCl → ZnCl2 + H2O

3 Mg + 2 H3PO4 → Mg3(PO4)2 + 3 H2

Cu+HCl= CuCl2 + H2(протекает при 600-700 гр Цельсия, реакция идет с HCl в газовом состоянии, а не с жидким HCl)

BaO + 2 HNO3 → Ba(NO3)2 + H2O

Fe2O3 + 6 HCl → 2 FeCl3 + 3 H2O

Answer 2

ZnO + HCl

When zinc oxide (ZnO) reacts with hydrochloric acid (HCl), it forms zinc chloride (ZnCl2) and water (H2O).

The balanced chemical equation for this reaction is:

ZnO + 2HCl → ZnCl2 + H2O

Mg + H3PO4

When magnesium (Mg) reacts with phosphoric acid (H3PO4), it forms magnesium phosphate (Mg3(PO4)2) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

3Mg + 2H3PO4 → Mg3(PO4)2 + 3H2

Cu + HCl

When copper (Cu) reacts with hydrochloric acid (HCl), it forms copper chloride (CuCl2) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

Cu + 2HCl → CuCl2 + H2

BaO + HNO3

When barium oxide (BaO) reacts with nitric acid (HNO3), it forms barium nitrate (Ba(NO3)2) and water (H2O).

The balanced chemical equation for this reaction is:

BaO + 2HNO3 → Ba(NO3)2 + H2O

Fe2O3 + HCl

When iron(III) oxide (Fe2O3) reacts with hydrochloric acid (HCl), it forms iron(III) chloride (FeCl3) and water (H2O).

The balanced chemical equation for this reaction is:

Fe2O3 + 6HCl → 2FeCl3 + 3H2O

Please note that these reactions are balanced chemical equations and represent the stoichiometric ratios of the reactants and products.
