What is chemical equation and example?
Representation of a chemical reaction in terms of symbols and chemical formula of the reactants and products taking part in the reaction is known as a chemical equation. For example, NH3+HCl→NH4Cl. , in this reaction ammonia and hydrochloric acid is reacting to form ammonium chloride. For solids, it is denoted by (s).
What are chemical reaction equations?
A chemical reaction equation gives the reactants and products, and a balanced chemical reaction equation shows the mole relationships of reactants and products. Often, the amount of energy involved in the reaction is given. Dealing with the quantitative aspect of chemical reactions is called reaction stoichiometry.
What is the importance of chemical equation?
Chemical equation gives information about the changes (State, chemical composition, heat energy) occurred in a chemical reaction. In order to write the chemical equation it is need to know the formulae of the elements or compounds which are involved in the chemical reaction.
What are the 3 parts of a chemical equation?
A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow.
What are the 4 types of chemical equation?
Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.
Is a color change a chemical reaction?
A color change may also indicate that a chemical reaction has occurred. A reaction has occurred if two solutions are mixed and there is a color change that is not simply the result of a dilution of one of the reactant solutions. A color change may also occur when a solid and liquid are mixed.
What are the main parts of chemical reaction?
There are three main parts to each chemical reaction: the reactants (left side of the reaction equation), the products (right side of the reaction…
What are 2 types of chemical reactions?
Types of Chemical Reactions
- Synthesis reactions. Two or more reactants combine to make 1 new product.
- Decomposition reactions. A single reactant breaks down to form 2 or more products.
- Single-replacement reactions.
- Double-replacement reactions.
- Combustion reactions.

What does a chemical equation tell chemist?
A chemical equation is an equation to show how atoms or molecules rearrange during any reaction. In order for a chemical equation to be correct, it must be balanced. It is much like an algebraic equation dealing with variables. Instead of Variables, it is molecules and atoms.
What is a basic chemical equation?
Chemical equation basics (Carrington, 9 min) In a chemical reaction, one or more reactants are transformed into products: reactants → products. The purpose of a chemical equation is to express this relation in terms of the formulas of the actual reactants and products that define a particular chemical change.
What are some examples of chemical equations?
A chemical equation is a method of expressing the reaction between various chemical elements. A very simple example is the reaction between hydrogen and oxygen to produce water: 2H2 + O2 = 2H2O.
What is the meaning of chemical equation?
Updated March 06, 2017. Definition: A chemical equation is a shorthand written description of what happens in a chemical reaction. It includes the reactants, products, direction(s) of the reaction, and may also include charge and states of matter.
