Lars is balancing equations with his study group. He is unsure about one equation because each member of the study group came up with a different answer. Which is the proper way to balance the equation Ca(OH)2 + H3PO4 → Ca3(PO4)2 + H2O? Ca(OH)2 + H3PO4 → Ca3(PO4)2 + 6H2O 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 3H2O Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O

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.  

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

the objects have the same charge is correct.
