Answer:
Kc of reaction is 20.
Explanation:
The two proteins are X and Y.
The [X] = 1mM
[Y]=1mM
At equilibrium, [X] = 0.2mM [Y] = 0.2mM
we know that equilibrium constant is:
Kc=![\frac{[Products]}{[Reactants]}=\frac{[XY]}{[X][Y]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BProducts%5D%7D%7B%5BReactants%5D%7D%3D%5Cfrac%7B%5BXY%5D%7D%7B%5BX%5D%5BY%5D%7D)
[XY]= 1-0.20=0.80 mM
putting values:
Kc=
Answer: option B. Hydrogen
Explanation:
When ketone is reacted with phosphorous pentachloride, chlorination takes place at the carbonyl carbon with substitution of the oxygen atom to give a geminal dichloride (with 2 Cl atoms on same carbon) according to the following equation:
so we can say that acetone is converted into 2,2-dichloropropane by action of PCl₅

<u>Answer:</u> The amount of heat required to warm given amount of water is 470.9 kJ
<u>Explanation:</u>
To calculate the mass of water, we use the equation:

Density of water = 1 g/mL
Volume of water = 1.50 L = 1500 mL (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:

To calculate the heat absorbed by the water, we use the equation:

where,
q = heat absorbed
m = mass of water = 1500 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature = 
Putting values in above equation, we get:

Hence, the amount of heat required to warm given amount of water is 470.9 kJ
