Consider RbOH → Rb+ + OH- and the following information.
AHlat = -765.01 kJ/mol
AHhydr of Rb+ = -315.2 kJ/mol
AHhydr of OH-=-532.7 kJ/mol
What is the AHsol rounded to the correct number of significant figures? Use A H sol = -A Hat + AHhydr-
-1.612.91 kJ/mol
-1,612.9 kJ/mol
-82.9 kJ/mol
-82.89 kJ/mol

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

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.
