Chemical reactions examples
A long time ago, humans knew chemical reactions. These reactions take place in all industrial, agricultural, as well as medical fields. You can also find them in household chores.
Chemical reaction with a simple definition is the addition of two substances or two chemical elements to each other in certain circumstances to produce a new chemical substance, knowing that not all chemicals are capable of interacting with each other.
The chemical elements don’t stop at those knowing elements, with passing the time and progress of sciences, scientists are discovering new chemical elements and substances.
The scientific definition of chemical reactions
It’s broking chemical bonds in the reacted substances for producing new bonds which are different from its chemicals and physiques properties.
There are some types of chemical reactions:
Oxidation and reduction reactions
These are chemical reactions when the electrons move between themselves which leads to oxidation of the reacted substances.
Union and annexation reactions
It’s a reaction between two substances or more for producing another new chemical substance.
These’re replacing or substituting an element with another element in a chemical component. These reaction depend on the chemical active of the element, the most active element replaces the less active element in the component.
In its, scientists use the heat or the electric energy for happening decomposition of an component to two components or a lot and it is the opposite of union reactions.
Now, let’s present some examples of chemical reactions:
It occurs as a result of a reaction between active molecules and oxygen to produce carbon dioxide and water vapor
An example is the combustion reaction of propane used in some ovens.
It occurs as a result of oxidation of the iron element due to its interaction with oxygen and water.
It is not a single chemical reaction but rather several chemical reactions that take place from eating food, so the Amylins enzyme in saliva breaks down sugars and carbohydrates into a simpler form that enables the body to absorb them.
When the food reaches the stomach, the hydrochloric acid reacts with the food to break it down, while the enzymes break down proteins and fats so that the body can absorb them.
One of the most unknown chemical reactions where we use heat to cause chemical changes in food and add elements to other elements to produce new compounds.
When an acid and a base are combined, a salt is formed.
When you combine an acid ,for example:
vinegar, lemon juice, sulfuric acid, muriatic acid with a base, for example :
baking soda, soap, ammonia, and acetone
you are doing a base reaction. These reactions neutralize the acid and base to produce salt and water.
Sodium chloride is not the only salt that can be formed. For example, the acid-base chemical reaction produces potassium chloride, which is a common substitute for table salt.
Soap binds to dirt and oily stains, so they can be removed with water. Detergents act as surfactants, reducing water surface tension so that it can interact with oils, isolate and rinse.
Respiration is a reversible process of photosynthesis in that energy molecules are combined with the oxygen we breathe in to release the energy that the body’s cells need in addition to carbon dioxide and water.
Unlike aerobic respiration, anaerobic respiration is a group of chemical reactions that allow cells to gain energy from complex molecules without oxygen. Where the muscle cells of the human body perform anaerobic respiration whenever a person breathes the oxygen that is delivered to them, such as during an intense or prolonged exercise.
Anaerobic respiration by yeast and bacteria is used to ferment to produce ethanol and carbon dioxide.
The process of photosynthesis
Chlorophyll in plant leaves converts carbon dioxide and water into glucose and oxygen. It is a chemical reaction carried out by plants to convert carbon dioxide and water into glucose and oxygen.
It is one of the most important daily reactions as plants produce food for themselves and animals and convert carbon dioxide into oxygen.
It is an example of electrochemistry and batteries use electrochemical or oxidation reactions to convert chemical energy into electrical energy. Spontaneous redox reactions occur in galvanic cells, while non-spontaneous reactions occur in electrolytic cells.
