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

The complete sentences are :
A) Angles 1 and 5 are <u>Congruent</u> because they are <u>Corresponding</u> angles
B) Angles 4 and 6 are <u>Supplementary</u> because they are <u>Same-side interior</u> angles
<h3>Determining the relationship between angles</h3>
Angles 1 and 5 are corresponding angles from the diagram and corresponding angles are congruent angles in geometry. while
Angles 4 and 6 are on the same side and are known as same-side interior angles. Summation of angles 4 and 6 add up to 180° therefore they are supplementary angles.
Hence we can conclude that the complete sentences realting to your question are as written above.
