The complete question is: Fill the blanks with appropriate coefficient number for the reaction equation- __AgNO3 + __Cu → __Ag + __Cu(NO3)2

Answer: The complete reaction equation is [tex]AgNO_{3} + Cu \rightarrow Ag + Cu(NO_{3})_{2}[/tex]

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, [tex]AgNO_{3} + Cu \rightarrow Ag + Cu(NO_{3})_{2}[/tex]

Here, number of atoms present on reactant side is as follows.

  • Ag = 1
  • [tex]NO_{3}[/tex] = 1
  • Cu = 1

Number of atoms present on product side is as follows.

  • Ag = 1
  • [tex]NO_{3}[/tex] = 2
  • Cu = 1

To balance this equation, multiply [tex]AgNO_{3}[/tex] by 2 on reactant side and multiply Ag by 2 on product side. Hence, the equation can be re-written as follows.

[tex]2AgNO_{3} + Cu \rightarrow 2Ag + Cu(NO_{3})_{2}[/tex]

Now, the number of atoms present on reactant side are as follows.

  • Ag = 2
  • [tex]NO_{3}[/tex] = 2
  • Cu = 1

Number of atoms present on product side are as follows.

  • Ag = 2
  • [tex]NO_{3}[/tex] = 2
  • Cu = 1

Thus, we can conclude that the complete reaction equation is [tex]AgNO_{3} + Cu \rightarrow Ag + Cu(NO_{3})_{2}[/tex].
