Answer 1

Одной чертой подчеркнуто то, из-за чего проходит данная реакция)

Answer 2

CUSO4+NAOH=cuOH+NASO
NA2SO4+BA(NO3)2=NA(NO3)2+BASO4
KOH+H2SIO3=SIK+H20
AgNO3+CUCI2=AgCI+CUN3
Fe(OH)3+HCI=FeCI+H2O

Answer 3

Reaction 1: CuSO4 + NaOH = ?

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

CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4

The balanced equation is: CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4 [[1]]

Reaction 2: Na2SO4 + Ba(NO3)2 = ?

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

Na2SO4 + Ba(NO3)2 = BaSO4 + 2NaNO3

The balanced equation is: Na2SO4 + Ba(NO3)2 = BaSO4 + 2NaNO3 [[2]]

Reaction 3: KOH + H2SiO3 = ?

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

2KOH + H2SiO3 = K2SiO3 + 2H2O

The balanced equation is: 2KOH + H2SiO3 = K2SiO3 + 2H2O [[3]]

Reaction 4: AgNO3 + CuCl2 = ?

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

2AgNO3 + CuCl2 = 2AgCl + Cu(NO3)2

The balanced equation is: 2AgNO3 + CuCl2 = 2AgCl + Cu(NO3)2 [[4]]

Reaction 5: Fe(OH)3 + HCl = ?

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

Fe(OH)3 + 3HCl = FeCl3 + 3H2O

The balanced equation is: Fe(OH)3 + 3HCl = FeCl3 + 3H2O [[5]]
