sladkih [1.3K]

Hello. This question is incomplete. The full question is:

"Scientists are testing the effect of different scrubber technologies on the removal of pollutants from coal power plants. The scrubbers use a slurry of limestone and water. Which of the following best describes the impact of modifying the slurry by increasing the amount of limestone? The amount of sulfur dioxide released will decrease. A The amount of ground-level ozone released will decrease. B The amount of water released will increase. C The amount of carbon monoxide released will increase. "

Answer:

The amount of sulfur dioxide released will decrease.

Explanation:

As you may already know, coal is a fossil fuel and burning it releases many toxic gases into the atmosphere, including sulfur dioxide.

A suspension of water and limestone, allows the calcium present in limestone to enter into reaction with sulfur dioxide, forming calcium sulfide and decreasing the emission of sulfur in the atmosphere.

The greater the amount of limestone in this suspension, the less sulfur dioxide will be released into the environment.

The cells within your own body, and within plants contain cytoplasm.  So two real life examples of cytoplasm would be the fluid in your own cells, and the fluid inside the cells of a tree.
