During chemistry lab, one lab group decomposes potassium chlorate to collect oxygen gas by water
displacement. the total volume is 220 milliliters and is collected at a pressure of 101 kpa at 24°c. the vapor
pressure of water at 24°c is found to be 2.98 kpa.
what is the pressure of the oxygen collected?
a)
98.02 kpa
98.2 kpa
101,20 kpa
104.28 kpa

explanation:

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.
