You will be working with calcium chloride; for 5 gm the temperature rose from 20.0 degrees C to 24.0 degrees C; for 10 grams the temperature rose from 19.6 degrees C to 27.6 degrees C; and finally for the 15 grams the temperature rose from 20.3 degrees C to 32.3 degrees C.
show all 3 delta H's that you calculate for your salt.
show your graph (with labels and title) and its calculated slope.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
