Question

Закончите молекулярные уравнения следующих реакций: TeO3+NaOH-> (NiOH)2SO4+NaOH-> BaCl2+CuSO4->

Answer 1

1) TeO3 + 6NaOH = Na6TeO6 + 3H2O
2) (NiOH)2SO4 + 2NaOH = Na2SO4 + 2Ni(OH)2 (неуверен)
3) BaCl2 + CuSO4 = BaSO4↓ + CuCl2

Answer 2

Закончите молекулярные уравнения следующих реакций:

1. TeO3 + NaOH -> ? 2. (NiOH)2SO4 + NaOH -> ? 3. BaCl2 + CuSO4 -> ?

1. TeO3 + 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.

The reaction between TeO3 (tellurium trioxide) and NaOH (sodium hydroxide) can be balanced as follows:

TeO3 + 2NaOH -> Na2TeO3 + H2O [[1]]

So, the balanced molecular equation for the reaction between TeO3 and NaOH is:

TeO3 + 2NaOH -> Na2TeO3 + H2O

2. (NiOH)2SO4 + 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.

The reaction between (NiOH)2SO4 (nickel hydroxide sulfate) and NaOH (sodium hydroxide) can be balanced as follows:

(NiOH)2SO4 + 2NaOH -> Ni(OH)2 + Na2SO4 [[2]]

So, the balanced molecular equation for the reaction between (NiOH)2SO4 and NaOH is:

(NiOH)2SO4 + 2NaOH -> Ni(OH)2 + Na2SO4

3. BaCl2 + CuSO4 -> ?

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.

The reaction between BaCl2 (barium chloride) and CuSO4 (copper(II) sulfate) can be balanced as follows:

BaCl2 + CuSO4 -> BaSO4 + CuCl2 [[3]]

So, the balanced molecular equation for the reaction between BaCl2 and CuSO4 is:

BaCl2 + CuSO4 -> BaSO4 + CuCl2

Please note that these balanced equations represent the molecular reactions between the given compounds.
