In this exercise, you will calculate molar value of ΔH (in kJ/mol) for dissolving NH4H2PO4 in Part D of the Calorimetry lab. What temperature change did you find for dissolving NH4H2PO4 in Part D of the experiment? (Include the + or - sign in your answer.)

i think it is true since you can test the answer and can use observations to complete it.

5 structural isomers

the isomers are:

n-exane :   ch3ch2ch2ch2ch2ch3

2-methylpentane :   ch3ch(ch3)ch2ch2ch3

3-methylpentane :   ch3ch2ch(ch3)ch2ch3

2,3-dimethylbutane :   (ch3)2chch(ch3)2

2,2-dimethylbutane :   (ch3)3cch2ch3
