__AgNO3 + __Cu → __Ag + __Cu(NO3)2

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

The complete reaction equation is

Explanation:

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

For example,

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

Number of atoms present on product side is as follows.

To balance this equation, multiply by 2 on reactant side and multiply Ag by 2 on product side. Hence, the equation can be re-written as follows.

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

Number of atoms present on product side are as follows.

Thus, we can conclude that the complete reaction equation is .

the correct answer would be d. hope this !
