Question

Interpreting a balanced chemical equation.

Answer 1

Balanced chemical equation is defined as the symbolic representation of a chemical reaction that has an equal number of atoms of each element in the reactant and the product. The chemical formula represents the reactant and the product.

Complete answer:
-In a balanced chemical equation the physical states are represented as : for solids $= \left( s \right)$ liquids $= \left( l \right)$ , gas $= \left( g \right)$ and aqueous $= \left( {aq} \right)$ .
For example:
$2{H_2}\left( g \right) + {O_2}\left( g \right) \to 2{H_2}O\left( l \right)$
-In this reaction hydrogen and oxygen are present in the gaseous form, whereas water is in the liquid state.
-In the balanced chemical equation, the reactants are written on the left side of the chemical reaction and the products are written on the right side of the reaction.
-From the balanced chemical equations we can interpret as follows:
-Relative masses of the reactants and products.
-The products and the reactant through the formulae and symbols.
-The ratio of molecules of the products and reactants.
-The limitations of balanced chemical equations are as follows:
-The balanced chemical equation does not give the information related to the rate of chemical reaction.
-The balanced chemical equation does not tell us the physical state of the chemical reaction.
-The balanced chemical equation does not tell us whether the reaction is reversible or irreversible.
-The balanced chemical equation does not give any information regarding temperature, pressure or the type of catalyst used in a chemical reaction.
-The balanced chemical equation does not give us the actual yield of the product.
-It does not tell us whether the heat has evolved or absorbed during the reaction.

Note: The balanced chemical equation does not give any information regarding temperature, pressure or the type of catalyst used in a chemical reaction. The balanced chemical equation does not give us the actual yield of the product.
