Write the balanced chemical equations for the following reactions. (AS1)
Zinc +Silver nitrateZinc nitrate+ Silver.
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
