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
2.99x12 = 35.88
35.88+13.99
49.87
Answer:
<h3>Disadvantage</h3>
It changes the cultural standards of the neighborhood. ...
Gentrification can sometimes make a community poorer. ...
It raises the cost of rent when it happens. ...
Gentrification replaces the people who built the community. ...
It causes the rich to get richer, while the poor may or may not benefit.
<h3>Advantage </h3>
On the positive side, gentrification often leads to commercial development, improved economic opportunity, lower crime rates, and an increase in property values, which benefits existing homeowners.
