I think this one is the “a wall of water that is pushed ashore”
Answer:
(2) Student A scored 15 points higher than student B
Explanation:
Because they said 15 points higher instead of their grades are better (The same thing 4 does.
Answer:
+2
Explanation:
Because an electron has a negative charge.
The compound is Molecular
Answer:
Shift it toward the products
Explanation:
Imagine this equilibrium:
2A + B ⇄ A₂B
Let's think the expression for Kc:
Kc = [A₂B] / [A]² . [B]
Now, we have this situation:
2A ↑ + B ⇄ A₂B
As we are not in equilibrium, we have to think that Kc would decrease.
↓Kc = [A₂B] / [A]² ↑ . [B]
so we have to use Qc (reaction quotient). For this case
Qc < Kc, so the reaction → Product side
We have to make more product to counteract the reagent increase and thus return the system to equilibriumr
