Answer:
Q.89
Alkane - CnH(2n+2)
given that 8 H = > 8= 2n+2
therefore n= 3
C3H8 = 12×3 + 8×1= 36 +8 = 44

Answer : The expression for solubility constant for this reaction will be,
Explanation :
Solubility product : It is defined as the product of the concentration of the ions that present in a solution raised to the power by its stoichiometric coefficient in a solution of a salt. This takes place at equilibrium only.
The solubility product constant is represented as, .
The dissociation of calcium phosphate is written as:
The expression for solubility constant for this reaction will be,
1077kjmol¹- + 498/2kjmol¹- + enthalpy=805*2kjmol¹- =1610-1319=291kjmol¹-
