A environmental scientist buys 20 gallons of oil eating bacteria to help remediate an area affected by an oil spill. The volume of water the scientist wants to cover with this bacteria is 5 ft³. What volume of water can the scientist cover with the bacteria she purchased? (1 gal = 0.13 ft³)

2.6  

Explanation:

Using the conversion factor:

1 gallon = 0.13

Therefore,

20 gallons = 20 x 0.13

       = 2.6‬  

This means that only 2.6   out of the 5   total volume of water the scientist wants to cover can actually be covered by the bacteria that was purchased.  

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
