<u>Answer:</u> The value of 
for the given reaction is 0.224
<u>Explanation:</u>
For the given chemical equation:
The expression of for given equation follows:
![K_c=\frac{[H_2][I_2]}{[HI]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5BI_2%5D%7D%7B%5BHI%5D%5E2%7D)
We are given:
![[HI]_{eq}=0.85M](https://tex.z-dn.net/?f=%5BHI%5D_%7Beq%7D%3D0.85M)
![[H_2]_{eq}=0.27M](https://tex.z-dn.net/?f=%5BH_2%5D_%7Beq%7D%3D0.27M)
![[I_2]_{eq}=0.60M](https://tex.z-dn.net/?f=%5BI_2%5D_%7Beq%7D%3D0.60M)
Putting values in above expression, we get:
Hence, the value of for the given reaction is 0.224
Answer:
The heat required to change 25.0 g of water from solid ice to liquid water at 0°C is 8350 J
Explanation:
The parameters given are
The temperature of the solid water = 0°C
The heat of fusion, = 334 J/g
The heat of vaporization, = 2260 J/g
Mass of the solid water = 25.0 g
We note that the heat required to change a solid to a liquid is the heat of fusion, from which we have the formula for heat fusion is given as follows;
ΔH = m ×
Therefore, we have;
ΔH = 25 g × 334 J/g = 8350 J
Which gives the heat required to change 25.0 g of water from solid ice to liquid water at 0°C as 8350 J.

Ozone is mainly found in two regions of the Earth's atmosphere. Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called thestratosphere.
