Consider a biochemical reaction that is taking place in a 0.1 m buffer. the initial ph is 7.4, and the pka of the buffer is 7.2. if, in a final reaction volume of 1.0 ml, 10 µmol of protons are generated, what would be the final ph of the solution?

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

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.
