Explanation:
As the given chemical reaction equation is as follows.
Also, it is given that for 2 moles the energy required is 130 kcal. This means that energy required for 1 mole is calculated as follows.
1 mole =
= 65 kcal
Hence, energy required for 7 moles will be calculated as follows.
Energy required =
= 455 kcal
Thus, we can conclude that energy required to produce 7.00 mol on the basis of given reaction is 455 kcal.
Answer:
Explanation:
Hello,
In this case, the molecular chemical reaction is:
Thus, by considering the ionic species we have:
Wherein the ammonium and bromide ions are spectator ions since nickel (II) phosphate is largely insoluble in water, therefore, the net ionic equation is:
