** ** how many atoms of each element does calcium sulfate, caso4, contain? calcium = 1 atom, sulfur = 4 atoms, oxygen = 4 atoms calcium = 1 atom, sulfur = 1 atom, oxygen = 4 atoms calcium = 4 atoms, sulfur = 4 atoms, oxygen = 4 atoms calcium = 4 atoms, sulfur = 1 atoms, oxygen = 4 atoms

Calcium = 1

Sulfur = 1

Oxygen = 4

Ik that the person who posted this already finished their test, but I wanted to answer for all of the people in the future who might look back on this question for help.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

i would say b

explanation:

but i think i would need more information than that
