Answer 1

Ответ:

1)2 NaOH + SO2 → H2O (l) + Na2SO3

2)Ca(OH)2+2Co2-->Ca(HCO3)2

3)NaOH + SO3 → NaHSO4

5)P2O5 + 6 NaOH → 2 Na3PO4 + 3 H2O

7)CuSO4 + 2 KOH → Cu(OH)2 + K2SO4

8)FeCl3 + 3 KOH → Fe(OH)3 + 3 KCl

10)ZnSO4 + 2 KOH → Zn(OH)2 + K2SO4

Answer 2

Balancing Chemical Equations:

1) NaOH + SO2 -> Na2SO3 - To balance this equation, we need to ensure that the number of atoms on both sides of the equation is equal. - The balanced equation is: 2NaOH + SO2 -> Na2SO3 [[1]].

2) Ca(OH)2 + SO2 -> CaSO3 + H2O - The balanced equation is: Ca(OH)2 + SO2 -> CaSO3 + H2O [[2]].

3) NaOH + SO3 -> Na2SO4 - The balanced equation is: 2NaOH + SO3 -> Na2SO4 [[3]].

4) Ca(OH)2 + SiO2 -> CaSiO3 + H2O - The balanced equation is: Ca(OH)2 + SiO2 -> CaSiO3 + H2O [[4]].

5) NaOH + P2O5 -> Na3PO4 - The balanced equation is: 6NaOH + P2O5 -> 2Na3PO4 [[5]].

6) NaOH + N2O5 -> NaNO3 + H2O - The balanced equation is: 2NaOH + N2O5 -> 2NaNO3 + H2O [[6]].

7) CuSO4 + 2KOH -> Cu(OH)2 + K2SO4 - The balanced equation is: CuSO4 + 2KOH -> Cu(OH)2 + K2SO4 [[7]].

8) FeCl3 + 3KOH -> Fe(OH)3 + 3KCl - The balanced equation is: FeCl3 + 3KOH -> Fe(OH)3 + 3KCl [[8]].

9) Al(NO3)3 + 3KOH -> Al(OH)3 + 3KNO3 - The balanced equation is: Al(NO3)3 + 3KOH -> Al(OH)3 + 3KNO3 [[9]].

10) ZnSO4 + 2KOH -> Zn(OH)2 + K2SO4 - The balanced equation is: ZnSO4 + 2KOH -> Zn(OH)2 + K2SO4 [[10]].

11) MgCl2 + 2KOH -> Mg(OH)2 + 2KCl - The balanced equation is: MgCl2 + 2KOH -> Mg(OH)2 + 2KCl [[11]].

Please note that the above equations are balanced based on the given reactants and products.
