Which of the following represents the net ionic equation when aqueous sodium chloride is mixed with aqueous silver nitrate? na+(aq) + no3−(aq) → nano3(aq) na+(aq) + cl−(aq) + ag+(aq) + no3−(aq) → agcl(s) + na+(aq) + no3−(aq) ag+(aq) + cl−(aq) → agcl(s) nacl(aq) + agno3(aq) → agcl(s) + nano3(aq)

answer; i believe the correct answer is (solid gold);

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
