Question

Write the advantages of writing a chemical equation using formulae and symbols.

Answer 1

A chemical equation is the shortest (almost always in one line) and most precise way of expressing a reaction. It gives a lot of information like:-

It tells us about the quality and quantity of reactants and products involved. Reactants on the left and products on the right

A single arrow between the reactants and products tells us that the reaction goes to completion while a double arrow shows that it is a reversible reaction

A balanced reaction gives the proportion of reactants and products; so when you don’t want to waste reactants (and this is very important if you are a factory owner not wanting to waste your profits); you can use these proportions to measure out the exact quantity of reactants. You can also know the exact amount of products you would get even before starting the process.

A reaction, written in details, also tells us about the physical state of the reactants and products

Similarly, the heat changes involved in a reaction are also written on the reaction.
