Final answer:
Particulates can be removed from stack exhaust gases by various methods such as electrostatic precipitators and filters.
Step-by-step explanation:
Particulate matter, also known as particle pollution, refers to solid particles and liquid droplets suspended in the air. These particles can be removed from stack exhaust gases through various methods such as electrostatic precipitators and filters. However, acid rain, ozone, and large suspended particles are not methods used to remove particulates from stack exhaust gases.
