Silver nitrate has lattice energy of -820kj/mol and a heat of solution of +22.6 kj/mol. calculate the heat of hydration for silver nitrate

Lattice energy = -820 kJ/mole

Heat of solution = +22.6 KJ/mole

Lattice breakdown is and endothermic reaction during the formation of solution

And hydration is an exothermic reaction as ions interact with solvent molecules

By using the formula,

Enthalpy of solution = Lattice energy + hydration energy

Now put the values and calculate,

+22.6 kj/mole = + 820 kj/mole + hydration energy

Hydration energy = 22.6 Kj/mole – 820 Kj/mole

Hydration energy= -797.4 Kj/mole

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
