Option A)
Magnesium chloride, MgCl2, is a binary compound with bonds with relatively high ionic character.
Answer: Water is the only known substance on Earth that exists naturally in three states: solid, liquid, and gas.
Explanation:
Answer:
[Al³⁺] = 1.62 M
[SO₄²⁻] = 2.43 M
Explanation:
Step 1: Given data
Molar concentration of Al₂(SO₄)₃: 0.811 M
Step 2: Write the reaction for the ionization of Al₂(SO₄)₃
Al₂(SO₄)₃(aq) ⇒ 2 Al³⁺(aq) + 3 SO₄²⁻(aq)
Step 3: Calculate the molar concentration of Al³⁺
The molar ratio of Al₂(SO₄)₃ to Al³⁺ is 1:2. The molarity of Al³⁺ is 2/1 × 0.811 M = 1.62 M.
Step 4: Calculate the molar concentration of SO₄²⁻
The molar ratio of Al₂(SO₄)₃ to SO₄²⁻ is 1:3. The molarity of SO₄²⁻ is 3/1 × 0.811 M = 2.43 M
The substance with pH are basic, so correct answer is <span>C) more OH- ions than H30+ ions.</span>
Answer:
It would become more neutral when diluted
Explanation:
Assuming you dilute it with water, the more diluted the substance, the more neutral (and closer to 7), it would be. Ie straight lemon juice is more acidic than lemonade, which is more acidic than water. I hope this helps :)
