The total reaction energy calculated by reactant bond energy - product
bond energy
The reactant bond energy is usually higher than that of the product bond
energy. This is as a result of the bonds in the product having higher bond
energy than the reactants.
<h3>What is Total reaction energy?</h3>
The total reaction energy is therefore calculated by subtracting the product
bond energy from the reactant bond energy so as to know the net energy
which was used in the reaction.

Answer:
The atomic number represents the number of protons
Explanation:
Chloroethane is the answer
Answer : The correct option is, (b) 22.5 M
Explanation : Given,
Mass of calcium nitrate tetrahydrate = 266 g
Molar mass of calcium nitrate tetrahydrate = 236.15 g/mole
Volume of solution = 
Molarity : It is defined as the moles of solute present in one liter of solution.
Formula used :
Now put all the given values in this formula, we get:
As calcium nitrate tetrahydrate dissociate to give 1 mole of calcium ion, 2 moles of nitrate ion and 4 moles of water.
The concentration of nitrate ion = 
Thus, the concentration of nitrate ion is, 22.5 M
