i dont know for sure, but i learned this in biology last year
Answer:
Heat of solution= - 63KJ/mole
Heat evolved = - 18.82KJ
Explanation:Heat of solution = Heat of solute + Heat of hydration
◇Hsoln = - ( - 7.3 × 10 ^ 2) + ( - 793 ) KJ / mol
◇H soln= - 63 KJ
Use enthalpy of solution equation to determine the enthalpy of solution for LiI
LiI ---> Li^ + + I^-
Molecular mass of LiI=133.85g
The chemical equation for the dissociation will be:
40gLiI (1molLiI)/133.85g LiI - 63KJ/1 mol LiI
18.82KJ
The heat was evolved because the value of enthalpy was negative
262. 5cm3.
using the Boyles law formula. p1v1=p2v2
P1=760torr.
v1=525cm³
p2=760×2=1520torr.
v2=?
p1v1=p2v2
760×525=1520×v2
v2=[ 760×525]÷1520
v2= 262.5cm³
when the pressure increases, the volume decreases.
