Answer:
4.1 mol·L⁻¹
Explanation:
You are diluting the solution with water, so you can use the dilution formula
c₁V₁ = c₂V₂ Divide each side by V₂
c₂ = c₁ × V₁/V₂
Data:
c₁ = 7.0 mol·L⁻¹; V₁ = 2.5 L
Water added = 1.5 L
Calculations:
(a) <em>New volume
</em>
V₂ = 2.5 L + 1.8 L
= 4.3 L
(b) <em>New concentration
</em>
c₂ = 7.0 × 2.5/4.3
= 7.0 × 0.581
= 4.1 mol·L⁻¹
Answer:
<h2>The answer is 1.5 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>1.5 L</h3>
Hope this helps you
Answer:
H₃O⁺ is the conjugate acid of H₂O
Explanation:
In the Bronsted-Lowry Theory, the product side acid and base are the conjugates of the reactant side acid and base. (F⁻ is the conjugate base of HF).
Answer:
gravity pull stuff down...
Explanation:
Oxygen is more <u>electronegative</u> than Hydrogen
So . . .
When the two form covalent bonds, oxygen pulls the electrons closer and farther from hydrogen
So . . .
The water molecule is <u>polar</u>, with oxygen more negative and hydrogen more positive.
So . . .
Since opposites attract, the more negative oxygens attract the more positive hydrogens of other water molecules, forming the <u>hydrogen bonds.</u>
