Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of th
If possible, make the equation more informative by indicating the physical states of the reactants and products, the heat changes that occur in the reaction, and the conditions under which the reaction occurs. This step may be skipped if you do not have enough information about the physical s...
A chemical equation is nothing but a mathematical statement which symbolizes the product formation from reactants. Q3 What are the chemical reaction types? On the basis of the product formed, different types of reactions are Combustion reaction, Decomposition reaction, Neutralization reaction, Redox ...
Such an equation is ‘unbalanced’ because the mass is not the same on both sides. Therefore, the above equation is a skeletal chemical equation for the reaction between magnesium and oxygen. Solved Examples for You Question: Why are iron articles painted? Solution: When iron comes in contact...

This lesson will cover what happens when a chemical reaction occurs, the types of chemical reactions, and how to know if a chemical reaction occurs.
A chemical reaction occurs when a chemical/substance undergoes a chemical change. A chemical change is something that changes the chemical identity of a substance as well as its chemical properties. There are several types of chemical changes. Examples of chemical changes include but are not limited...
Let’s take a closer look at the types of reactions and get examples: Synthesis or Direct Combination Reaction In a synthesis, direct combination, or composition reaction, two (or more) reactants combine to form a more complex product. The general form of the reaction is: A + B → AB ...
this type of reaction, a single reactant, a compound, breaks into two or more parts. Often these are the most difficult to predict. Here is the general equation: AB→A + B where A and B may be either elements or compounds. Here are some examples of decomposition reactions:
Over time, iron develops a red, flaky coating called rust. This is anexample of an oxidation reaction. Other everyday examples include the formation of verdigris on copper and the tarnishing of silver. Here is thechemical equationfor the rusting of iron: ...
