Calculate the pH of the solution that results from each of the following mixtures. The ionization constants required in this exercise are found in Appendix II, page A-12, of your textbook:

The acidity constant Ka of HF is 3.5×10−4.

The basicity constant Kb of C2H5NH2 is 5.6×10−4.

Caculate pH
180.0 mL of 0.12 M C2H5NH2 with 285.0 mL of 0.22 M C2H5NH3Cl

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
