Answer:
are there answer choices with the question?
Explanation:
sorry im a little confused
Answer:
By putting a coefficient 4 on NaI and 2 on Na₂SO₄
4NaI + Pb(SO₄)₂ → Pbi4 + 2Na₂SO₄
Explanation:
- A chemical equation is balanced for it to obey the law of conservation of mass.
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products.
- Balancing involves putting coefficients on reactants and products to get an equal number of atoms of each element on either side of the equation.
- In this case, putting a coefficient four on NaI and two on Na₂SO₄ will make the equation to be balanced.
- Therefore, the balanced chemical equation is;
4NaI + Pb(SO₄)₂ → Pbi4 + 2Na₂SO₄
<h3>Answer:</h3>
1.0 × 10⁻⁶ M (Option-A)
<h3>Solution:</h3>
Data Given:
pH = 6
[H⁺] = ?
Formula Used:
As we know pH is given as,
pH = -log [H⁺]
and,
[H⁺] = 10^-pH ----- (1)
Putting value of pH in eq. 1,
[H⁺] = 10⁻⁶ ∴ 10 = Antilog
[H⁺] = 1.0 × 10⁻⁶ M
