Using the following facts, determine the ounces of 80 proof whiskey that must be drunk for an average person with 7.0 liters of blood to be declared legally intoxicated using dimensional analysis. a. 15% by weight of alcohol ingested actually reaches the blood
b. density of ethanol = 0.80 g/mL
c. 80 proof = 40% by volume
d. 1 oz. = 30 mL

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.
