Question

9 multiple choice 1 point what term is used to describe a substance that can adsorb water vapor as it passes through a fixed bed? a desiccant a reactant a dehumidifier a blow dryer 10 multiple choice 1 point which fuel gas component has the highest number of carbon atoms per molecule? propane pentane ethane butane

Explanation:

For question 9: A desiccant is a substance that adsorbs water vapor from a gas stream passing through a fixed bed. A reactant participates in a chemical reaction, a dehumidifier is a device (not a substance), and a blow dryer is an appliance that uses airflow to dry, not adsorb vapor.
For question 10: The prefixes in alkane names indicate carbon count: eth-=2, prop-=3, but-=4, pent-=5. Pentane has the highest number of carbon atoms per molecule.

Answer:

1. A desiccant
2. Pentane
