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.

<h3><u>Answer;</u></h3>
A. have a full outer electron shell
<h3><u>Explanation</u>;</h3>
- Noble gases are elements that are found in Group 18 of the periodic table. They include, Neon, Argon, Krypton, Xenon, etc.
- <em><u>The outer shell of valence electrons is considered to be “full” in noble gases, giving them little tendency to participate in chemical reactions. This means they have an octet configuration.</u></em>
- They are all monatomic gases under standard conditions, including those with larger atomic masses than many other elements that are solids under standard conditions.
