Students in chemistry course were asked the following question on a unit exam: "Draw a diagram representing an element using circles as atoms."
a. The following diagrams represent the two types of answers given by students. Which is the drawing best representation of an element? Explain.
b. imagines that the atom in drawing B had been removed from one of the substances used earlier.
i. List the codes of the substances that "drawing B" could have come from through physical separations?

I need more help with part b. plz

the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

i'm pretty sure it is letter c.) car

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.
