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

What volume of 0.158 M Na3PO4 solution is necessary to completely react with 88.0 mL of 0.109 M CuCl2?
(Express your answer in millimeters)

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
