1. what is the role of a heat exchanger?

a) move feedstock through pipes
b) transfer heat between fluids
c) separate solids from liquids
d) perform reactions

1. which equipment divides mixtures into parts?

a) pump
b) separator
c) reactor
d) heat exchanger

1. where do chemical reactions occur?

a) separator
b) pump
c) reactor
d) heat exchanger

Explanation:

1. Unit operations are the building blocks of processes in chemical engineering - related to the basic steps in a process.
2. A pump moves liquids through pipes. It is a common function of pumps in industrial set - ups.
3. A heat exchanger transfers heat between fluids by bringing them into close thermal contact while keeping them physically separated.
4. A separator divides mixtures into parts by using physical or chemical means to separate components based on their properties.
5. Chemical reactions occur in a reactor where reactants are brought together under specific conditions to cause a chemical change.

Answer:

1. a) Building blocks of processes
2. b) Moves liquids through pipes
3. b) Transfer heat between fluids
4. b) Separator
5. c) Reactor
