Answer:
- 484 KJ/mol
Explanation:
The reaction equation is;
CH4(g) + F2 (g) ------> CH3F(g) + HF(g)
The enthalpy of the reaction can be calculated from bond energies using the formula;
ΔHreaction = Bond energy of reactants - bond energy of products
or
ΔHreaction = Bonds broken - bonds formed
[4(413) + 1(155) - 3(413) + 1(485) + 1(567)]
[(1652 + 155) - (1239 + 485 + 567)]
[1807 - 2291]
= - 484 KJ/mol
Answer: 12%
Explanation:
Since the ointment contains 12 gms of active ingredient with 100 gms of ointment base, the concentration of the active ingredient in the ointment will be:
= Content if active ingredient/Content of ointment base × 100
= 12/100 × 100.
= 12%
Therefore, the the concentration of the active ingredient in the ointment is 12%.
