Answer:
(i think) it is A difference in 1 unit is a 10X difference in concentration For example; a liquid with pH of 3 is 10X more acidic than a liquid with a pH of 4. Therefore, a liquid with a pH of 3 is stronger.

Answer:
concentration of
= 0.0124 = 12.4 ×10⁻³ M
concentration of
= 0.0248 = 2.48 ×10⁻² M
concentration of
= 0.4442 M
Explanation:
Equation for the reaction:
⇄
+ 
Concentration of
=
= 0.469
For our ICE Table; we have:
⇄
+ 
Initial 0.469 0 0
Change - 2x +2x +x
Equilibrium (0.469-2x) 2x x
K = ![\frac{[CO]^2[O]}{[CO_2]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCO%5D%5E2%5BO%5D%7D%7B%5BCO_2%5D%5E2%7D)
K = ![\frac{[2x]^2[x]}{[0.469-2x]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B2x%5D%5E2%5Bx%5D%7D%7B%5B0.469-2x%5D%5E2%7D)

Since the value pf K is very small, only little small of reactant goes into product; so (0.469-2x)² = (0.469)²




![x=\sqrt[3]{1.9929*10^{-6}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B1.9929%2A10%5E%7B-6%7D%7D)
x = 0.0124
∴ at equilibrium; concentration of
= 0.0124 = 12.4 ×10⁻³ M
concentration of
= 2x = 2 ( 0.0124)
= 0.0248
= 2.48 ×10⁻² M
concentration of
= 0.469-2x
= 0.469-2(0.0124)
= 0.469 - 0.0248
= 0.4442 M
Answer:
No effect will be observed since C is not included in the equilibrium expression.
Explanation:
Let's consider the following reaction.
CO₂(g) + C(graphite) ↔ 2 CO(g)
The equilibrium constant (Kc) is the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.
Kc only includes gases and aqueous species (not liquids or solids).
![Kc=\frac{[CO]^{2}}{[CO_{2}]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BCO%5D%5E%7B2%7D%7D%7B%5BCO_%7B2%7D%5D%7D)
As we can see, C is a solid and is not included in the equilibrium expression, so adding some C would have no effect on it.
