Answer :

Zn + AgNO3 Zn(NO3)2 + Ag

Balanced equation: Zn + 2AgNO3 Zn(NO3)2 + 2Ag


Explanation:


Step 1: Write the given unbalanced equation


Zn + AgNO3 Zn(NO3)2 + Ag


Step 2: Compare the number of atoms of reactants with the number of atoms of products.



Step 3: Now, first we consider the element having unequal no. of atoms on both sides. Thus, let us consider nitrogen atom first. If we multiply 2 in the reactant (in AgNO3), we will get the equal number of atoms as in product (Zn(NO3)2)



Step 4: Write the resulting equation:


Zn + 2AgNO3 Zn(NO3)2 + Ag


Step 5: Now check whether the equation is balanced or not by comparing the atoms



We find that the equation is not balanced yet. As the number of silver atoms are unequal on the two sides.


Step 6: Now, let us consider silver atom. If we multiply 2 in the product (in Ag), we will get the equal number of atoms as in reactant (in 2AgNO3)



Step 7: Write the resulting equation:


Zn + 2AgNO3 Zn(NO3)2 + 2Ag


Step 8: Now check whether the equation is balanced or not by comparing the atoms.



We find that the equation is balanced now.


Step 9: Write down the final balanced equation:


Zn + 2AgNO3 Zn(NO3)2 + 2Ag
