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 matching of the demand as relatively elastic or relatively inelastic can be done as;
- Klaus' demand for orange juice (Relatively elastic)
- Amanda's annual demand for coffee(Relatively elastic)
- Jackson's demand for mystery novels(Relatively inelastic)
- Hermy's demand for Minute Maid orange juice(Relatively inelastic)
- Olivia's daily demand for Starbucks latte(Relatively inelastic)
- Stephen spends a very little part of his income on soda(Relatively elastic)
- Xavier's demand for his economics textbook(Relatively inelastic)
<h3>What is Elasticity of demand?</h3>
Elasticity of demand can be regarded as the variation on the concept of demand.
It should be noted that elastic demand involves change in quantity demanded as a result of change in price.

The volume of the prism is the amount of space on the prism
The volume of the cylinder is 760 cubic units
<h3>How to determine the volume?</h3>
The question is incomplete.
So, we make use of the following parameters
- Shape = Cylinder
- Radius, r = 11
- Height, h = 2.
The volume of a cylinder is calculated using:
V = πr²h
Substitute known values in the above formula
V = 3.14 * 11² * 2
Evaluate the product
V = 759.88
Approximate
V = 760
Using the assumed values, the volume of the cylinder is 760 cubic units
