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

Answer:
I consider myself as a good test taker. If I do not prepare for a test then I will get a low grade. When I prepare for a big tests I pull out my notebook, textbook and highlighters and begin to highlight and study all the key points in that subject. PSAT allows me to get a feel for the SAT studying for the PSAT will follow through and give me skills that I will need to take the SAT.

Based on the vertices and the pre-order traversal order the tree would be visited is e, i, b, h, f, a, c, d, g.
<h3>What order will the tree be visited?</h3>
When using the pre-order traversal, the order would be from the root child node to the left child node to right child node.
The root node is the highest node which is e. From here you'll then proceed to the left roots first which means you'll go to i and then b.
From there you go to h and then f. The next nodes would be a and c.
Continuing from left to right, you'll then go to d and then g.
You'll therefore start from "e" and move to "i" and then "b" to "h" and then "f" and "a" to "c" and then to "" and finally to "g"
