One important drawback of the use of hcfcs as a replacement for cfcs is that hcfcs are more potent greenhouse gases.
<h3>
What is hcfcs?</h3>
HCFCs is an acronym for hydrochlorofluorocarbons (HCFCs).
Thye are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), derived from alkane family.
<h3>What is cfcs?</h3>
CFCs is an acronym for Chlorofluorocarbons (CFCs), derived from alkane family like hydrochlorofluorocarbons.
<h3>Disadvantage of hcfcs over cfcs</h3>
One important drawback of the use of hcfcs as a replacement for cfcs is that hcfcs are more potent greenhouse gases.

Answer:
Kₐ = 4.06 × 10⁻⁷
Explanation:
Step 1. <em>Calculate [H₃O⁺]
</em>
pH = 3.94
[H₃O⁺] = 1.15 × 10⁻⁴ mol·L⁻¹
Calculate 
HF + H₂O ⇌ H₃O⁺ + F⁻
I/mol·L⁻¹: 0.0326 0 0
C/mol·L⁻¹: 0.0326-1.15 × 10⁻⁴ +1.15 × 10⁻⁴ +1.15 × 10⁻⁴
E/mol·L⁻¹: 0.0325 1.15 × 10⁻⁴ 1.15 × 10⁻⁴
So, at equilibrium,
[H₃O⁺] = [F⁻] = 1.15 × 10⁻⁴ mol·L⁻¹
[HF] = 0.326 – 1.15 × 10⁻⁴ mol·L⁻¹ = 0.0325 mol·L⁻¹
Kₐ = {[H₃O⁺][F⁻]}/[HF]
Kₐ = (1.15 × 10⁻⁴ × 1.15 × 10⁻⁴)/0.0325
Kₐ = 1.32 × 10⁻⁸/0.0325
Kₐ = 4.06 × 10⁻⁷
This is <em>NOT</em> a solution of HF (Kₐ = 7.2 × 10⁻⁴). It is more likely a solution of carbonic acid (H₂CO₃; Kₐ₁ = 4.27 × 10⁻⁷).
Answer:
Increasing Surface Area
Explanation:
A greater surface area (meaning more, smaller particles) allows for more opportunity for particles to collide. On the other hand, decreasing temperature and removing a catalyst would only decrease the number of collisions, and the clumping option doesn't make much sense. Hope this helps!
Answer:
Convection is the transfer of heat energy in a fluid. ... Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks.
Explanation:
They are different.... Because the chemical reaction will change the way its chemical makeup is
