When 1. 0 l of 0. 00010 m NaOH and 1. 0 l of 0. 0014 m mgso4 are mixed, there will be no precipitate formed.
<h3>What is a precipitate?</h3>
The precipitate is the solid concentration of a substance that is collected over a solution.
First, we determine the concentration of magnesium and hydroxide
(Mg2+) = 7.00 × 10⁻⁴
(OH−) = 5.00 × 10⁻⁵
Now, we calculate the solubility quotient
Qc = (Mg2+) (OH−) ²
Qc = 7.00 × 10⁻⁴ x (5.00 × 10⁻⁵)²
Qc = 1.75 x 10⁻¹²
The solubility product of the magnesium hydroxide is 1.80 x 10⁻¹¹ which is more than the solubility quotient. Thus, there will be no precipitate form.
Thus, there will be no precipitate formed because the solubility quotient we calculated is less than the solubility product.

Answer: Fe2O3
Explanation:
100 grams of iron ore = 30.06% oxygen
100 - 30.06 = 69.94% iron
Mr of Iron = 55.85
Mr of Oxygen = 16
Iron = 69.94/55.85 = 1.252
Oxygen = 30.06/16 = 1.879
1.879 / 1.252 = 1.5 of Oxygen
1.252/1.252 = 1 of Iron
we can write that as Fe1O1.5 but we can't use decimals therefore we have to multiply the whole thing by 2
So it comes out to be Fe2O3
