Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
I think its Gillian. Look it up in case
here are the reasons why Maggie did not have a flood insurance.
C. She felt she needed to save money.
D. She may have misunderstood her basic homeowners policy.
E. Her expenses were already high before paying for insurance.
According to the question, Maggie did not have enough money. She already had more than enough expenses.
The passage also said that there were months that the amount that she had was hardly enough to take care of basic needs.
She did not understand the home owners policy because she was told that they would offer it to her at an additional cost. She may have thought that she already had it covered.
