Consider the following precipitation reaction: 2Na3PO4(aq)+3CuCl2(aq)→Cu3(PO4)2(s) +6NaCl(aq)

What volume of 0.182 MNa3PO4 solution is necessary to completely react with 89.0 mL of 0.120 MCuCl2?

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
