question 100

Multiple Choice

Calculate the standard enthalpy change for the reaction 2C₈H₁₈(l) + 21O₂(g) → 8CO(g) + 8CO₂(g) + 18H₂O(l) . Given:
2C₈H₁₈(l) + 25O₂(g) → 16CO₂(g) + 18H₂O(l) ΔH° = -11,020. kJ/mol
2CO(g) + O₂(g) → 2CO₂(g) ΔH° = -566.0 kJ/mol

Definitions:

Normal Good

A good that has a positive income elasticity, so that as consumer income rises, demand for the good rises, too.

Market Supply

The total quantity of a good or service that sellers are willing and able to sell at a given price over a specific period.

Elasticity

Elasticity refers to the measure of how much the quantity demanded or supplied of a good changes in response to a change in price.

Normal Good

A good for which demand increases as the income of consumers increases and decreases as the income of consumers decreases.
