Answer:
m = 1.5 gram
Explanation:
Given that,
Density of protein gelatin, d = 3 g/L
The volume of protein gelatin, V = 0.5 L
We need to find the mass of the protein gelatin. The density of an object is given by :
d = m/V
Where
m is mass
So, the required mass is 1.5 gram.

Answer:
The change in entropy of the surrounding is -146.11 J/K.
Explanation:
Enthalpy of formation of iodine gas =
Enthalpy of formation of chlorine gas =
Enthalpy of formation of ICl gas =
The equation used to calculate enthalpy change is of a reaction is:
For the given chemical reaction:
The equation for the enthalpy change of the above reaction is:
Enthaply change when 1.62 moles of iodine gas recast:
Entropy of the surrounding =
1 kJ = 1000 J
The change in entropy of the surrounding is -146.11 J/K.
Answer : The maximum amount of nickel(II) cyanide is
Explanation :
The solubility equilibrium reaction will be:
Initial conc. 0.220 0
At eqm. (0.220+s) 2s
The expression for solubility constant for this reaction will be,
Now put all the given values in this expression, we get:
Therefore, the maximum amount of nickel(II) cyanide is
