How many moles of cu are needed to react with 3.00mples of agno3

equation: cu + 2agno3--> cu(no3)2 + 2ag

1.5 mol of Cu

Explanation:

Cu + 2AgNO3--> Cu(NO3)2 + 2Ag

From the equation,

1mole of Cu required 2moles of AgNO3.

Therefore, Xmol of Cu will require 3 moles of AgNO3 i.e

Xmol of Cu = 3/2 = 1.5 mol

  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-
