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
The answer is I have no idea really
Answer:
b = 56.67 m
Explanation:
It is given that,
Area of the triangular field is 255 m²
We need to find the base of the field if its height is 9 m.
The area of a triangle is given by :
So, the base of a triangle is 56.67 m.
The permanent magnet in the loudspeaker is fixed close to a mobile electromagnet coil. The electromagnet is attached to a flexible material called cone (). Passing an electric current in the electromagnet causes it to vibrate due to the interaction with the permanent magnet.Uh hope this helped.
B add the atomic number to the number of neutrons
