Answer: polymerization.


Justification:


Poly means many, and monomer means parts.


Then, a polymer is a compound made of many smaller molecules, and the process to form a polymer is named polymerization.


Polymers are large molecules formed by the combination of of many repeated units (monomers).


Some polymerization reaction are adition and condensation.


Some very well know polymers are polyethilene, nylon, pvc, polyester, among many other. They are also known as plastics.

When 100 mL of 1.0 M Na3PO4 is mixed with 100 mL of 1.0 M AgNO3, a yellow precipitate forms and [Ag ] becomes negligibly small.
lana [24]

Answer:

Na3PO4 + 3AgNO3 -------> Ag3PO4 + 3NaNO3

In which [Ag+] in negligibly small and the concentration of each reactant is 1.0 M

The answer is A)  PO43- < NO3- < Na+

Explanation:

Ag+ is removed from the solution just like PO43-, so there are just 2 possible answers at this point: a or b. Then we can notice that Na3PO4 releases 3 moles of Na+ and just 1 mole of NO3-

We have 100mL of each reactant with the same concentration for both (1.0 M) so:

(0.1)(1)(3)= 0.3 mol Na+

(0.1)(1)= 0.1 mol NO3-

so PO43- < NO3- < Na+
