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>

Answer:
is the overall voltage produced
Explanation:
Potassium and Tin are connected in an electrochemical series.
In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.
Here,
The voltage drop at potassium 
The voltage drop at Tin 
The net voltage

Most likely use scientific names and list the procedures taken
Answer:
None of these statements are true
Explanation:
(a)
Heavier and large molecules or atoms exhibit greater dispersion force than lighter ones due to easily form temporary dipoles by large molecule.
(b)
Compounds with hydrogen bonding usually have higher boiling point than that of similar compound without hydrogen bonding,
Because boiling point of a compounds depends on force of attraction between the molecules.
(c)
Non polar compounds usually have lower boiling points than polar compounds of similar mass due to dipole dipole attractive force of polar compound.
