Answer:
the words to identify them is them in kaps right
Explanation:
All of the above
4Li + O₂ = 2Li₂O lithium oxide
2Na + O₂ = Na₂O₂ sodium peroxide
K + O₂ = KO₂ potassium superoxides
Answer:
Because they are electrical conductors because their delocalized electrons carry electrical charge through the metal. they are good conductors of thermal energy because their delocalized electrons transfer energy.

When base is added in order to increase the pH of a solution, it results in MOH salt <u>precipitating first.</u>
Equation :
MOH (s) ⇄ M⁺ (aq) ₊ OH⁻(aq)
K
= [M⁺] [OH⁻]
K
= 1.39×10⁻¹² and [M⁺] = 0.001M
∴ 1.39×10⁻¹² = (0.001M) [OH⁻]
[OH⁻] = 1.004×10⁻¹⁹M
pOH = -log [OH⁻] = 11.9
pH = 14 - pOH
= 14 - 11.9
<u>pH = 2.1</u>
