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 might have something that helps! Has two solutions x = a and x = -a because both numbers are at the distance a from 0. You begin by making it into two separate equations and then solving them separately. An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

The land of the coastal plain to be softer than the land of the piedmont coastline because the terrain is low-lying.
The Piedmont is a region in the eastern United States that stretches for about 600 miles (950 km) from New Jersey to Alabama in the north and from the Atlantic Coastal Plain in the south (east).
The Coastal Plain gradually increases in elevation as it moves more inland from the "Pine Barrens," although it seldom reaches over 500 feet above sea level. The soil in this area is composed of sand, clay, and other elements. The peaches, pecans, and peanuts grown in this bountiful region, along with many other agricultural goods, are world-famous.
"Pine Barrens" region of the state is unfit for agriculture even now. On the property, pine trees are largely grown for grazing and for the production of turpentine, pulp, and other products.
