AP Classroom B(aq)+HCl(aq)⇄HB+(aq)+Cl−(aq)

The graph above shows the titration curve for an aqueous solution of a weak base, B, with HCl as the titrant. Based on the graph, which of the following best estimates the pKa of HB+?

A 12.0

B 10.8

C 6.0

D 1.8

THE ANSWER IS B

thats how its supposed to be

i don,t know so just answer mine

b. is the answer hoped i        

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.
