Answer:
a. True
Explanation:
From the basic concepts of acids and bases, we know that when a base accepts a hydrogen ion (H⁺), it forms a conjugate acid which can accept again the H⁺ ion:
B⁻ + H₂O ⇆ BH + OH⁻
The stronger the base, the weaker the conjugate base. Thus, as more strength has a base, lesser strength will have the conjugate base (it will not be able to accept again the H⁺ ion). For example, when water (H₂O) loses its H⁺ , it forms the conjugate base OH⁻. So, OH⁻ is the stronger base that can exist in an aqueous solution.
H₂O ⇆ H⁺ + OH⁻
In fact, strong bases are hydroxides, such as NaOH or KOH.
<u>Answer:</u> The partial pressure of oxygen is 160 mmHg
<u>Explanation:</u>
We are given:
Percent of oxygen in air = 21 %
Mole fraction of oxygen in air = 
To calculate the partial pressure of oxygen, we use the equation given by Raoult's law, which is:
where,
= partial pressure of oxygen = ?
= total pressure of air = 760 mmHg
= mole fraction of oxygen = 0.21
Putting values in above equation, we get:
Hence, the partial pressure of oxygen is 160 mmHg
A). Until they have a stable nucleus.
I think d is wrong because Everything else is correct for sure. also, minerals vary in the position they hold and have different chemical compounds.
The balanced equation for the dissolving of aluminum chloride into an aqueous solution with the dissociation of the ions is; AlCl3(s) → Al^3+ (aq) + 3 Cl^-(aq).
<h3>What is an equation?</h3>
An equation is a representation of the change that occurs inside a reaction vessel. Usually, we use this tool to show on paper, a process that we can not see with or eyes.
The equation that shows the balanced equation for the dissolving of aluminum chloride into an aqueous solution with the dissociation of the ions is; AlCl3(s) → Al^3+ (aq) + 3 Cl^-(aq).
