Question

What is an example of a balancing chemical equations practice problem?

Answer 1

Hint: A chemical equation is a method of expressing a chemical reaction, including the symbols and formulas of the substances involved. A balanced chemical equation has the same number of atoms on both sides (reactant and product) of different elements, and a chemical equation with unequal atomic numbers of one or more elements on both sides is called an unbalanced chemical equation.

Complete Step By Step Answer:
We know that a chemical equation is a way of expressing a chemical reaction, including the symbols and formulas of the substances involved. Chemical equations can be balanced or unbalanced. A balanced chemical equation has the same number of atoms on both sides (reactant and product) of different elements, and a chemical equation with unequal atomic numbers of one or more elements on both sides is called an unbalanced chemical equation.
The reaction of sulfuric acid and potassium bicarbonate is an acid-base neutralization reaction. Sulfuric acid is an acid and potassium bicarbonate is a base. We obtain products such as water, carbon dioxide and potassium sulfate. First write the unbalanced chemical equation.
 $ KHC{O_3} + {H_2}S{O_4} \to {K_2}S{O_4} + C{O_2} + {H_2}O $
We can see that one potassium is missing on the right. So in order to balance the equation, we will put 2 there as a coefficient.
 $ 2KHC{O_3} + {H_2}S{O_4} \to {K_2}S{O_4} + C{O_2} + {H_2}O $
We can see that one potassium is missing on the right. So in order to balance the equation, we will put 2 there as a coefficient.
 $ 2KHC{O_3} + {H_2}S{O_4} \to {K_2}S{O_4} + 2C{O_2} + 2{H_2}O $
We can see that the above chemical equation is balanced.

Note:
For the oxidation-reduction reaction, the half equation method is used, because the oxidation-reduction reaction is difficult to trial and error. If you can, you can also use trial and error to balance the redox reaction. Due to the law of conservation of mass, the chemical equation must be balanced, which states that mass cannot be created or destroyed.
