Remember that <span>λ, or wavelength, is proportional to (1/f), where f=frequency. That means that wavelength and frequency are inversely related. When one goes up, the other goes down, and vice versa. That means answers C and D are incorrect because those answers have wavelength and frequency in a direct relationship.
Radiant energy is directly proportional to frequency. When frequency increases, radiant energy increases. That means A) </span><span>As wavelength decreases, radiant energy and frequency increase is the correct answer.</span>
It requires more energy to boil an substance than to melt it (with special exceptions). When something is boiled you are furthering the distance between the already stretched out molecules which will require more energy to do so, also in most cases you will be creating a vapor from boiling which has a high kinetic energy value.
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>

120 barrels = 15120 quarts
To convert from barrels to quarts, you just need to multiply the value in barrels by 126 (the conversion factor).
So, 120 barrels = 120 × 126 = 15120 quarts.
