What are the answer choices?
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
When Eleanor Roosevelt says, "There is such a thing as going through the world blindfolded. I have known people who were quite unconscious of the play of the sun and shadow on the hills," she means people can fail to recognize the beauty in the world. This means that these people rarely take advantage of opportunities in life.
The wife of President Franklin D. Roosevelt, Eleanor Roosevelt was the first lady of the United States of America from 1933 to 1945. During this tenure, Roosevelt championed poverty alleviation, access to education and civil rights as well as travelled to the European and Pacific front lines, when the world was engaged in World War II.
