Different Types of Chemical Reactions | TutorVista
Substitution reactions can be a bit confusing at times, as they can sometimes appear to go backwards as well. It depends on what other chemicals are present at the same time to help them go they way we want them to. If you wrote the first example backwards, it would be a reaction.
i.e. CH3CH2Cl + H2O ---> CH3CH2OH + HCl
Often we use a large excess of the chemical supplying the incoming group to force the reaction to go the way we want. So we would use concentrated HCl to force the first example the way we want it to go. If we started with the chloroethane and added lots of water, the HCl formed in the hydrolysis reaction would be very dilute, so the first reaction is overpowered and doesn't occur.
Don't worry if this seems a bit confusing at first, everyone finds it tricky to begin with, especially if isn't part of their course - it is usually not part of the very first courses taught at schools.

Reactant are the substances present at the beginning of a chemical reaction. In the burning of natural gas, for example, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction.
How do trees grow? What about flowers? Vegetables of any kind? All of these plants require photosynthesis, which is a chemical reaction that plants use to grow. Plants that rely on photosynthesis for survival produce grains, sugar, and many other goodies. Without chemical reactions, cookies just wouldn't be the same.

In simple terms, one substance gains oxygen (or loses hydrogen) and another loses oxygen (or gains hydrogen). This is explained in more detail in the tutorials on this topic on the , which you should read next, especially if you are on an advanced course which uses the electron gain/loss definition. But here are a couple of examples to help you along. There are many examples of this type of reaction in all chemistry courses.

Products are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.

According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. Therefore, the amount of the atoms in each element does not change in the chemical reaction. As a result, the chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
