Explanation:
number bonds are pairs of numbers that can be added together to make another number e.g. 4 + 6 = 10. They are some of the most basic and most importantparts ofmaths for children to learn
The reason is it has more sugar and energy to feed fungi, causing it to mold.
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
