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

Explanation: I took the test.
There re a lot of laws. The law that applies to a driver while driving in the rightmost lane in the pictures attached is the move over law.
<h3>What is the Move Over Law?</h3>
This is known to be a law that requires you to Move Over a lane. Here, one can safely do so due to the fact that they have stopped law enforcement, emergency, sanitation, etc.
A Move Over law is a also known as a law which requires any motorists to move over and change lanes so as to get a safe clearance to law enforcement officers, firefighters, etc.
