Which of the following scenarios would drive the reaction below to the left? 2A+B+ Energy >< symbol thingy C+D

1 answer:

6 0

Answer:
A. Adding D

Explanation:
Based on Le Chatelier's principle, a chemical reaction will reach equilibrium when the rate of the forward reaction is equal to the rate of the backwards (reverse) reaction.
Adding more reactants will cause the equilibrium to shift to the right and form more products in order to reach equilibrium again.
While adding more products will shift the equilibrium to the left and form more reactants in order to reach equilibrium again.

In the given question, we need the equilibrium to shift to the left and form more reactants. This means that we will need to add more products.
Therefore, we will need to add either C or D.

Applying this to the choices, we will find that the correct choice is A.

Hope this helps :)

Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.

And I don't see any of the particles. so I can only answer the first one.

Determine the total kilojoules in two tablespoons of crunchy peanut butter that contains 6 g of carbohydrate, 11 g of fat, and 9

lara31 [8.8K]

Answer:

665 kJ

Explanation:

We assume that carbohydrates and protein each have 4 kilocalories per gram, and that fat has 9 kilocalories per gram. Then the number of kilocalories in the peanut butter is ...

4(6 +9) +9(11) = 159 . . . . kilocalories

Each kilocalorie translates to 4.184 kilojoules, so the total is ...

(159 kCal)(4.184 kJ/kCal) = 665.256 kJ

2 Tbsp of crunchy peanut butter contains about 665 kJ of energy.
