Why do you use chemical equation?

Answer 1

being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form

Answer 2

A chemical equation shows us what happens in a chemical reaction by telling us the substances we started off with and the substances we end up with after the reaction has taken place.

In a chemical equation, we have both reactants and products. Reactants are the substances you start off with and products are the substances you end up with after the reaction has taken place.

Reactants --> Products

A + B --> C + D

If we look at this equation, we can see that A and B are the reactants in this chemical equation whereas C and D are the products of this chemical equation. This tells us that A and B have reacted with each other to form C and D.

Answer 3

Chemical formulas are used because they show the chemical make up of a substance. Chemical equations are used because it is much easier to use symbols as a shorthand way of describing and visualizing a chemical reaction, rather than writing it out in words.

Answer 4

Chemical Reactions are used everywhere, particularly in the body, in which they are used for changing starch into energy, etc.

Answer 5

Chemists use chemical equations to describe what happens in a chemical reaction. The equations save time and space and provide the information in an easy to read form.

Answer 6

The purpose of chemical equations is to make clear what is happening within a chemical reaction and to record each element in each compound that is involved with the reaction.
