Answer : The balanced chemical reaction will be:

$CuO+H_2SO_4\rightarrow CuSO_4+H_2O$

Explanation :

As per question when copper(II) oxide react with sulfuric acid then it gives copper(II) sulfate and water.

This reaction is known as double displacement reaction in which cation of two reactants exchange their places to give two different products.

The balanced chemical reaction will be:

$CuO+H_2SO_4\rightarrow CuSO_4+H_2O$

4.5 moles of sodium sulfate contain how many atoms of sulfur

Hatshy [7]

Chemical Formula of Sodium Sulfate is Na₂SO₄.

As we know, 1 mole of any substance contains 6.022 × 10²³ particles. So, 1 mole of Na₂SO₄ also contains 6.022 × 10²³ formula units of Na₂SO₄.
Also,
1 mole of Na₂SO₄ contains = 6.022 × 10²³ Atoms of S
So,
4.5 moles of Na₂SO₄ will contain = X atoms of S

Solving for X,
X = (4.5 moles × 6.022 × 10²³ Atoms) ÷ 1 mole

X = 2.70 × 10²⁴ Atoms of S
Result:
4.5 Moles of Na₂SO₄ contains 2.70 × 10²⁴ Atoms of Sulfur.
