Answer 1

Нашел там не все но коешто есть ))
) 6NaOH+P2O5= 2Na3PO4 + 3H2O

Fe2O3+ 6HNO3= 2Fe(NO3)3 + 3H2O

SO2+CaCl2= реакция не идет

Cu(OH)2+KOH = на счет этой реакци точно не уверена, но думаю, что она тоже не идет, т.к. гидроксид меди 2 является осадком

Mg(OH)2+BaCl2= Ba(OH)2 + MgCl2

FeSO4+Pb(NO3)2= PbSO4 + Fe(NO3)2

Na2SO4+HCl= реакция не идет

Al2(SO4)3+3BaCl2 = 3BaSO4 + 2AlCL3

CuO+H2O= реакция не идет, т.к. оксид меди 2  не растворим в воде

ZnCl2+2AgNO3= 2AgCl + Zn(NO3)2

Answer 2

Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance each equation one by one:

1. NaOH + P2O5 → Na3PO4 - To balance the equation, we need 3 NaOH and 1 P2O5 on the left side. - The balanced equation is: 3 NaOH + P2O5 → Na3PO4.

2. Fe2O3 + HNO3 → Fe(NO3)3 + H2O - To balance the equation, we need 2 Fe2O3, 6 HNO3, 6 Fe(NO3)3, and 3 H2O on the right side. - The balanced equation is: 2 Fe2O3 + 6 HNO3 → 6 Fe(NO3)3 + 3 H2O.

3. SO2 + CaCl2 → CaSO3 + Cl2 - To balance the equation, we need 2 SO2 and 2 CaCl2 on the left side. - The balanced equation is: 2 SO2 + 2 CaCl2 → 2 CaSO3 + Cl2.

4. Cu(OH)2 + KOH → K2Cu(OH)4 - To balance the equation, we need 2 Cu(OH)2 and 2 KOH on the left side. - The balanced equation is: 2 Cu(OH)2 + 2 KOH → K2Cu(OH)4.

5. Mg(OH)2 + BaCl2 → MgCl2 + Ba(OH)2 - To balance the equation, we need 1 Mg(OH)2 and 1 BaCl2 on the left side. - The balanced equation is: Mg(OH)2 + BaCl2 → MgCl2 + Ba(OH)2.

6. FeSO4 + Pb(NO3)2 → PbSO4 + Fe(NO3)2 - To balance the equation, we need 1 FeSO4 and 1 Pb(NO3)2 on the left side. - The balanced equation is: FeSO4 + Pb(NO3)2 → PbSO4 + Fe(NO3)2.

7. Na2SO4 + HCl → NaCl + H2SO4 - To balance the equation, we need 2 Na2SO4 and 2 HCl on the left side. - The balanced equation is: 2 Na2SO4 + 2 HCl → 2 NaCl + H2SO4.

8. Al2(SO4)3 + BaCl2 → BaSO4 + AlCl3 - To balance the equation, we need 2 Al2(SO4)3 and 3 BaCl2 on the left side. - The balanced equation is: 2 Al2(SO4)3 + 3 BaCl2 → 3 BaSO4 + 2 AlCl3.

9. CuO + H2O → Cu(OH)2 - To balance the equation, we need 1 CuO and 1 H2O on the left side. - The balanced equation is: CuO + H2O → Cu(OH)2.

10. ZnCl2 + 2 AgNO3 → 2 AgCl + Zn(NO3)2 - To balance the equation, we need 2 ZnCl2 and 2 AgNO3 on the left side. - The balanced equation is: 2 ZnCl2 + 2 AgNO3 → 2 AgCl + Zn(NO3)2.
