What is balanced chemical equations ? Why it should be balanced ? Give one example
Answers
Explanation:
chemical equation shows the chemical formulas of substances that are reacting and the substances that are produced. The number of atoms of the reactants and products need to be balanced. In this lesson, we will discuss balancing chemical equations.
Balancing Chemical Equations
Let's take a look at this scale. We can see that it is unbalanced, with the right (red) side, weighing more than the left (blue) side. In order for the two sides to be balanced, we need to put a little more mass on the left side until they are the same mass.
Unbalanced Scale
Just like we want the scale to be balanced on both sides, a chemical equation should also be balanced on both sides. A chemical equation shows us the substances involved in a chemical reaction - the substances that react (reactants) and the substances that are produced (products). In general, a chemical equation looks like this:
Chemical Equation: General Form
According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. Therefore, the amount of the atoms in each element does not change in the chemical reaction. As a result, the chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side
Answer:A chemical equation in which the total mass of the elements present in the reactants is equal to the total mass of elements of product is called a BALANCED EQUATION.
according to the law of conservation of mass, mass can neither be created nor be destroyed but if the no. of atoms on both the reactants and product is not same,we need to balance the equation.hence to satisfy the law of conservation of mass,the chemical equations are balanced.
