The coefficients in a chemical equation tell how many molecules of that type are reacting. The arrows point in the direction of the reaction. Ex. 2 H + 1 O -> 1 H2O has two hydrogen molecules interacting with one oxygen molecule to form one water molecule.

What do the subscript and coefficent in a chemical equation tell us?

The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.


What does a balanced equation tells us?

A balanced equation has equal numbers of each type of atom on each side of the equation.Chemical equations usually do not come already balanced.It tells "Matter is neither created nor destroyed."Therefore, we must finish our chemical reaction with as many atoms of each element as when we started.


What information you get from chemical equation?

You get the reactants, products, and the ratio that the chemicals react in. It also gives information on what processes the chemicals are undergoing, such as oxidation/reduction and acid/base.


Does a chemical formula describes a chemical reaction?

Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.


How do chemists indicate a reversible reaction when writing a chemical equation?

Theoretically, chemical equations are reversible but in reality this is not true. Combustion is not normally written as a reversible reaction unless in an extreme hypothetical sense. Generally, one cannot tell if a chemical equation is reversible. It is a matter of experience and study.

What is a purpose of a chemical equation?

A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.


What are the advantage of biochemistry?

What are the Importance of stoichiometry in chemical reactions?

stoichiometry is very important in chemical equations because it tells you the relationship between substances in the same chemical equation. If you know the properties and relationship of one substance in the equation, you can calculate the relationships between all the substances in the equation.


What does the equation Emc2 tell us?

It tells us how much energy is available in any given mass and of course also the reverse.
