Acertain commercial process relies on the addition of nh4no3 to a solution of their proprietary compound. the junior apprentice chemist develops a plan to add 6.55 pounds of nh4no3 to 14.0 gallons of water. the water in the factory is typically at an initial temperature of 18.0 c, and the temperature of the water cannot drop below 15 c, or the reaction will be too slow. will the above plan work? use the value of delta hrxn = +25.7 kj/mol.

Final temperature 13.71 C the plan won't work

Explanation:

Reaction:

Mol of

Mol of water  

The reaction stoichiometry is 1:1 so the with 36.93 mol is the limit reagent in the reaction.

The energy for this reaction is:

The process is getting this energy from the water for that reason the temperature of the water will decrease.

Q necessary for the reaction is  

[

The heat given by the water will be the same but with a different sign

[

We estimate the water’s final temperature, with this equation:

Clearing for T2 we get:

mass of water =52920g

Cp=4.186 J/g*C

hope you got the answer

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
