Enumerate any two differences between simple distillation and fractional distillation.
mr_godi [17]

Answer:

Explanation:

By simple distillation, we can separate tow miscible liquids having sufficient difference in their boiling points.

By fractional distillation, we can separate the mixture of two or more miscible liquids for which the difference in their boiling point is less than 25k

Simple distillation is done using an air condenser or water condenser.

Fractionating column is fitted in between the distillation flask and the condenser for the process.

Simple distillation eg: mixture of water and acetone

fractional distillation eg: crude oil

Consider the following chemical equilibrium: CaCO3 (s) Cao (s)+cO2 (g) Now write an equation below that shows how to calculate K
True [87]

Answer:

Kc = Kp/(RT)

Explanation:

Let's consider the following chemical equilibrium:

CaCO₃(s) ⇄ CaO(s) + CO₂(g)

Given the pressure equilibrium constant Kp = pCO₂

We can calculate the concentration equilibrium constant (Kc) using the following expression.

Kc = Kp/(RT)^{\Delta n(g)}

where,

R is the ideal gas constant

T is the absolute temperature

Δn(g) = moles of gaseous products - moles of gaseous reactants = 1 - 0 = 1

The expression for this reaction is:

Kc = Kp/(RT)

How is the separation of dna like a zipper
Sedbober [7]

The two strands must be separated like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.

<u>Explanation:</u>

  • A double helix structure formed by two polypeptide chains is separated like the two sides of a zipper. A zipper is formed by breaking the weak hydrogen bonds that link the paired bases. During replication, an enzyme "Helicase" travels down the DNA and splits the chain and it forms 2 separate strands.
  • The two DNA strand which has the same sequence must be separated like the two sides of a zipper by breaking weak hydrogen bases. During base pair-rule, the strand are unzipped and each strands is copied.

Please help with this chemistry question above!
Lady_Fox [76]

Hey there!

Your answer is B. CO₂.

This molecule consists of two polar bonds, but they cancel each other out because they are pointing away from each other.

Because the forces of the bonds cancel out, the molecule itself is nonpolar.

Hope this helps!
