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.

What factor defines all groups in the Köppen system, with the exception of dry climates? evaporation precipitation air pressure
Liula [17]

Answer:

temperature

Explanation:

I choose temperature because it tells how hot,cold,dry and warm somethings are meanwhile evaporation is when water changes from liquid to gas,so that means water gets hot.

Precipitation is when water released from the cloud to form rain,freezing rain,sleet,snow,or hail.Which means thing get cold.

Air pressure also affect evaporation, which means that water will not be able to come up of the surface of a body of water.So that means the the pressure will be pushing down on the surface of the water.
