Zero degree celcius = 273.15 degree kelvin
Simply, to get the value of 45.1 degree celcius in kelvin, we will add 273.15 to the given value (45.1).
Degree in kelvin = 45.1 + 273.15 = 318.25 degree kelvin
Approximating to the nearest tenth, the value will be 318.3 degree kelvin
Answer:
1.12 x 10²³atoms of F
Explanation:
Number of MgF₂ atoms = 5.6 x 10²² molecules;
The unknown here is the number of Fluorine atoms found in the compound.
In MgF₂,
1 mole of MgF₂ contains 2 moles of F;
From the given number of molecules we can also say that, MgF₂ contains 5.6 x 10²²atoms;
1 mole of MgF₂ contains 2 moles of F;
5.6 x 10²²atoms of MgF₂ will contain 2 x 5.6 x 10²² = 1.12 x 10²³atoms of F

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>
