Answer: okay this should get you started
Explanation:
From he calculations, we can see that the total pressure at equilibrium is 21 atm.
<h3>What is equilibrium constant?</h3>
The term equilibrium constant commonly describes the constant that that shows the extent of conversion of reactants to products.
We have to find the pressure of each gas as follows;
For H2
P = nRT/V = 4.553 /2 × 0.082 × 1000/8.89 L = 21 atm
Using the ICE table;
C(s) + 2H2(g) ⇌ CH4(g)
I 21 atm 0
C -x +x
E 21 - x x
0.263= x/(21 - x )^2
0.263(21 - x )^2 = x
38 - 11x - 0.263x^2 = x
0.263x^2 + 12x - 38 = 0
x=2.97 atm
At equilibrium, we have;
(21 - 2.97) + 2.97 = 21 atm

Answer:
The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H+ ions in solution and therefore only a little change in pH.
Explanation:
When a strong acid is added to the buffer, the acid dissociates and furnish hydrogen ions which combine with the conjugate of the weak acid, forming weak acid. The weak acid dissociates to only some extent and can furnish only some protons and there is no significant change in the pH.
Hence, option B is correct.
Answer:
Amount of energy was released
Explanation:
Because when energy is release from the shell it makes the electron lose and than go to higher level of energy form
C. Yes; a false hypothesis gives a scientist new information to use.
