Please answer this question

Consider the following system at equilibrium:

Vika [28.1K]

Answer:

1) Rightward shift

2) Rightward shift

3) Leftward shift

4) Leftward shift

5) Leftward shift

6) Rightward shift

7) No shift

8) No shift

Explanation:

To evaluate each case we need to consider Le Chatelier's Principle, which states that the adding of additional reactants or products to a system will shift the equilibrium in the opposite direction, to maintain the equilibrium of the system. On the contrary, if we remove a reactant or a product in the system, the equilibrium will be shifted in the direction of the reactant or product reduced, to produce more of it (and thus maintain balance).

Taking into account the above, let's see each statement, in the following equation:

A(aq) + B(aq) ⇄ 2C(aq) (1)

1) Increase A. This will cause a rightward shift in equation 1 in order to consume the reactant added.

2) Increase B. Same as 1), this will cause a rightward in equation 1.

3) Increase C. This will cause a leftward shift in order to consume the excess of product in the system.

4) Decrease A. This will produce a leftward shift to produce the reactant that is being reduced.

5) Decrease B. Same as 4), a leftward shift.

6) Decrease C. This will produce a rightward shift to produce the product that is being reduced.

7) Double A, half B. The double A will cause a rightward shift and the half B will produce a leftward shift, which results in no shift.

8) Double both B and C. Double B will produce a rightward shift and double C will produce the contrary, a leftward shift, so the final result is no shift.

I hope it helps you!

What is the percent composition of CuCl2?

allochka39001 [22]

CuCl2 is Dichloride Copper, or Copper II Chloride.
In this Molecule, there is 1 atom of Copper for every 2 atoms of Chlorine.
If you go to the periodic table, you'll see that copper has a mass of 63.5 amu, and the chlorine 35.45 amu.
Which mean that the mass of CuCl2 is 63.5 + 35.45*2 = 63.5 + 70.9 = 134.4 g/mol.
Then, you find the ration of the mass of each atom and multiply by 100.
Ratio of Copper: $\frac{63.5}{134.4} * 100$ and you get about 47.2%
Ration of chlorice (Cl2): $\frac{70.9}{134.4} * 100$ and you get about 52.8%.

So, the percent composition of CuCl2 is 47.2% of Copper and 52.8% of chlorine.

Hope this Helps :)

the radius of the Sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. Express

Mazyrski [523]

Explanation;

Writing scientific notation :

Move the decimal to the left side until single digit of number remains before the decimal.
Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
For Example: $2894.55=2.89455\times 10^{3}$
