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>

Hello there! A proton has a positive charge of (+1) and has a lesser mass compared to a neutron! Hope this helps! Have a great day!
Answer: 1.) His action is not justified because he could have done something else like talking with someone.
2.) Some of the negative consequences could be Mr. King could lose his job or worse not be able to teach again.
3.) Some other options were having him retake the test or talking to the head of the school, or many other things.

The concentration in mol/L of the chemist's potassium iodide solution : = 4.4 x 10⁻⁴ M
<h3>Further explanation</h3>
Given
88. μmol of Potassium iodide
200. mL volumetric flask
Required
The concentration
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Conversion :
88. μmol = 88 . 10⁺⁶ mol = 8.8 10⁻⁵ mol
200 ml = 0.2 L
The molarity :
= n : V
= 8.8.10⁻⁵ : 0.2
= 4.4 x 10⁻⁴ M
