Answer:
1. This reaction is <u>(A) Exothermic .</u>
2. When the temperature is decreased the equilibrium constant, K: <u>(A) Increases</u>
3.When the temperature is decreased the equilibrium concentration of Co2:<u> (A) Increases</u>
Explanation:
1. The pink color predominates at low temperatures, indicating that the commodity is preferred.
This is a reaction that is <u>exothermic.</u>
2. As the decrease in the temperature , the equilibrium constant , K ;
equilibrium constant = 
=![\frac{[CO^2^+][Cl^-^4]}{CoCl^2^-_4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCO%5E2%5E%2B%5D%5BCl%5E-%5E4%5D%7D%7BCoCl%5E2%5E-_4%7D)
As the temperature drops, the concentration of
and 
rises, and K rises as well , thus it <u>increases </u>.
3. The equilibrium concentration of decreases as the temperature decreases:
When the temperature is lowered, the equilibrium shifts to the right , that is it <u>increases.</u>
Answer:
what is cocococococo?
Explanation:
isnt it like a plant for choclate?
Because cl atoms are bonded with hydrogen. hydrogen bond is very strong bond
The volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L (option B).
<h3>How to calculate volume?</h3>
The volume of a substance can be calculated using the following formula:
P1V1 = P2V2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
153 × 3 = 304 × V2
459 = 304V2
V2 = 459/304
V2 = 1.51L
Therefore, the volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L.
