Acid&Base: Conducts electricity
Given molecule Lithium iodide (LiI)
Heat of hydration = -793 kj/mol
Lattice energy = -730 kJ/mol
Heat of hydration = Heat of solution - Lattice energy
Heat of solution = Hydration + Lattice = -793 + (- 730) = -1523 kJ/mol
Now,
Mass of LiI = 15.0 g
molar mass of LiI = 134 g/mol
# moles of LiI = 15/134 = 0.112 moles
Heat of solution for 1 mole of LiI = -1523 KJ
Therefore, for 0.112 moles of LiI the corresponding heat is
= 0.112 *(-1532) = 171.6 kJ
A cation is a positively charged ion,
so cation is A. H⁺.
<span>1 mile = 4 min.
1 mile = 1.61 km
1.61 km = 4 min
4 min * 15 = 60 min = 1 hr
24.15 km = 60 min or 1 hr</span>
