A researcher recorded that a chemical reaction required 2.90 gal water and raised the temperature of the reaction vessel by 57 F
Bess [88]

<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>

<u>Explanation:</u>

Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.

We have to convert the researcher's volume into the SL units of liter.

<em>So, we know that 1 gallon = 3.875 liters</em>.

Then we have to convert 2.90 gallons of water in to liters.

Then  , volume in L =(volume\ in \ gal) \times  (3.875 L/1 gal)                                   = (2.90) \times (3.875L/1 gal)                                  

= 11.0L

<em>Then the required volume in L= 11.0L</em>

Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
