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

Thesis statement which is used for an essay which analyzes kincaid uses literary element is explained below.
Explanation:
In the novel Lucy by Jamaica Kincaid talks about a young girl whose name is Lucy. This fiction written by Jamaica is a little different than the other fictions written by him.
In this fiction she does not use repetition and surrealism like she uses in the other fictions. In the novel, Lucy is older than other protagonists and thus this fiction has a more mature and a cynical perspective than the other fictions written by her.
Lucy: A Novel is a narrative covering one year in the life of Lucy Josephine Potter, who recently immigrated to the United States from the West Indies.
She has never liked her middle and last names, which are reminders of an impoverished uncle and the white Englishmen who colonized her island. Although she wishes her first name was more solemn—like "Charlotte" or "Emily," the names of her favorite authors—she is proud that her mother named her after Lucifer, the devil.
The name defines who she is not just in attitude and personality but in relationship to her mother, whom she views as a godlike being. Lucy reveals her name to readers in the last chapter of the book—when she feels she has finally become her own person.
