Answer 1

Ответ:

Объяснение:

1)  3Ba(NO3)2 + Аl2(SO4)3  = 3BaSO4 + 2Al(NO3)3

2) 2HNO3 + Zn(OH)2 = Zn(NO3)2 + 2H2O

3) 3MgO + 2H3PO4  = Mg3(PO4)2 + 3H2O

4) 2Al + 3CuSO4 = Al2(SO4)3 + 3Cu

Answer 2

Chemical Equations:

1. Nitrate of barium + sulfate of aluminum: - Equation: Ba(NO3)2 + Al2(SO4)3 → BaSO4 + 2Al(NO3)3 - Explanation: When barium nitrate (Ba(NO3)2) reacts with aluminum sulfate (Al2(SO4)3), it forms barium sulfate (BaSO4) and aluminum nitrate (Al(NO3)3) [[1]].

2. Zinc hydroxide + nitric acid: - Equation: Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O - Explanation: When zinc hydroxide (Zn(OH)2) reacts with nitric acid (HNO3), it forms zinc nitrate (Zn(NO3)2) and water (H2O) [[2]].

3. Magnesium oxide + phosphoric acid: - Equation: MgO + H3PO4 → Mg3(PO4)2 + H2O - Explanation: When magnesium oxide (MgO) reacts with phosphoric acid (H3PO4), it forms magnesium phosphate (Mg3(PO4)2) and water (H2O) [[3]].

4. Aluminum + copper (II) sulfate: - Equation: 2Al + 3CuSO4 → Al2(SO4)3 + 3Cu - Explanation: When aluminum (Al) reacts with copper (II) sulfate (CuSO4), it forms aluminum sulfate (Al2(SO4)3) and copper (Cu) [[4]].

Please note that these equations represent the balanced chemical reactions.
