What is a balanced chemical equation? Why should chemical equations be balanced?
Answer :
Ans:
Balanced Chemical Equation is an equation in which the total number of atoms of each element in the reactants,on the left side of the equation,is the same as the number of atoms in the products formed, on the right side of the equation.
Why should Chemical Equation be balanced?
$$ Zn +H_{2}SO4 \rightarrow ZnSO_{4} + H_{2}$$
Element Name | In Reactants | In Products |
---|---|---|
No. of Zn atoms | 1 | 1 |
No.of H atoms | 2 | 2 |
No.of S atoms | 1 | 1 |
No.of O atoms | 4 | 4 |
Thus above reaction between zinc and dilute sulphuric acid is a balanced equation.
