what is the purpose of the condenser? question 3 options: a) to de-superheat the entering vapor, condense the vapor to a liquid,
Alona [7]

Option (a) is correct,

the purpose of the condenser is to de-superheat, the entering vapor, condense the vapor to a liquid, and subcool the liquid.

<h3>What is a condenser's purpose?</h3>

A condenser uses a cooling fluid to attempt to sufficiently cool down a vapor, changing its state from a vapor to a liquid. Condensers come in a variety of designs, including direct condensing, which involves coming into direct touch with the cooling fluid and the vapor.

<h3>What kind of vapor is condensed?</h3>

The vapour that needs to condense might be highly different and can even include non-condensable vapour, such as air, which greatly affects how well the condenser works.

Consider the following chemical equilibrium:
jok3333 [9.3K]

Answer:

Kc = [CH₄] / [H₂]²

Kp = [CH₄] / [H₂]² * (0.082*T)^-1

Explanation:

Equilibrium constant, Kc, is defined as the ratio of the concentrations of the products over the reactants. Also, each concentration of product of reactant is powered to its coefficient.

<em>Pure solids and liquids are not taken into account in an equilibrium</em>

Thus, for the reaction:

C(s)+ 2H₂(g) ⇌ CH₄(g)

Equilibrium constant is:

<h3>Kc = [CH₄] / [H₂]²</h3>

Now, using the formula:

Kp = Kc* (RT)^Δn

<em>Where R is gas constant (0.082atmL/molK), T is the temperature of the reaction and Δn is difference in coefficients of gas products - coefficients of gas reactants (1 - 2= -1)</em>

Replacing:

<h3>Kp = [CH₄] / [H₂]² * (0.082*T)^-1</h3>

Why do covalent bonds not involve the transfer of electrons
zhannawk [14.2K]
Covalent bonds do not involve electron transfer because in covalent bonds, the electrons are shared between the atoms to form the molecule rather than being transferred to form ions as it is in the case of ionic bonds.<span />
