THIS NEEDS TO BE ANSWERED ASAP THIS IS DUE TOMORROW!!! a. Neon is considered a pure substance. What do you observe about the molecules?
b. Could the other molecules in this simulation (argon, oxygen, and water) be considered pure substances? Explain your thinking.
If you answer this correctly I will give brainliest and 100 points!!

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

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.
