What is chemistry? Get to know her beautifully

 What is chemistry

Chemistry is the science that studies matter and its properties, how and why substances combine or separate to form another substance and how it interacts with energy.Many people think that chemists wear a white coat and they test and mix strange liquids in the laboratory, but in fact we are all chemists. Understanding basic chemistry concepts is part Important for nearly every profession.


Everything in existence is made up of matter, even our bodies.Chemistry is present in everything we do, like farming, cooking food, cleaning our homes and our bodies, and even launching a space rocket. Chemistry is one of the physical sciences that helps us describe and explain our world.



 

Departments of Chemistry

Chemistry is divided into 5 major departments, each of which has several fields of study.


Analytical chemistry: Qualitative and quantitative observation is used to define and quantify the physical and chemical properties of substances.


Physical chemistry: This section combines chemistry and physics. Both thermodynamics and quantum mechanics are two important branches of physical chemistry.


Organic chemistry: This section is concerned with the study of compounds that contain the element carbon, as carbon has many unique properties that allow it to form complex chemical bonds and very large molecules. Organic chemistry is known as (the chemistry of life) because all the molecules that make up living tissues have carbon as part From its composition.


Inorganic chemistry: It studies materials that are not part of carbon, such as minerals and gases.


Biochemistry: It is the study of the chemical processes that occur within living organisms.



 

fields of study

There are many and varied fields of study within these departments, many of which have a direct impact on our daily life. Chemists strive to improve many things, such as the food we eat, the clothes we wear, and the materials used to build our homes. Chemistry helps protect our environment and search for new sources of energy.


Food Chemistry: Food science deals with the basic components of food, which are carbohydrates, fats and proteins.


Carbohydrates are sugars and starches, and they are the chemical fuel for cells to function efficiently.


Fats, along with oils, are key parts in making cell membranes lubricate the systems inside our bodies.


Proteins are complex molecules composed of 100 to 500 or more amino acids that are linked in chains together and folded into a three-dimensional form that is appropriate for the structure and function of each cell.


Environmental Chemistry: Chemists study how chemicals interact with the natural environment.


Chemists in this field try to understand the chemicals and chemical reactions involved in natural processes in water, air, and soil.


Agricultural chemistry: Agricultural chemistry is related to substances and chemical reactions associated with the production, protection and use of crops and livestock.


It is a multidisciplinary field that overlaps with many other sciences.


Chemists in this field are developing the fertilizers, pesticides and herbicides needed to produce more efficient crops.


Chemical Engineering: Chemical engineers research and develop new materials or processes that involve chemical reactions.


Chemical engineering combines the concepts of chemistry, engineering, and economics to solve technological problems.


The job of a chemical engineer is based on industrial applications and developing a new product.


Geochemistry: Geochemistry combines chemistry and earth sciences (geology) to study the formation and interactions between materials found on the earth.


Often, chemists in this field spend more time doing field studies than other chemical sciences.


Chemists may work in the oil and gas industry to help find new sources of energy reserves.


They may also work on pipelines and oil platforms to prevent chemical reactions that could cause explosions or spills.



 

Forensic chemistry: Chemists in this field capture and analyze physical evidence left over at crime scenes to help identify the identities of the people involved and also to answer other vital questions regarding how the crime occurred.


Forensic chemists use a wide variety of methods of analysis, such as chromatography and spectroscopy.

Stages of human fetus formation.

 Changes week by week! Pregnancy is defined as the period between the inception of the fetus (fertilization) and birth, that is, during the growth and development of the child in the mother's womb. And because it is impossible to know exactly when the fetus was conceived; The gestational age is calculated from the first day of the mother's last menstrual period. It is calculated in weeks. This means that during the first and second weeks of pregnancy, a woman in it is not yet pregnant. This is when her body prepares to receive the fetus. A normal pregnancy lasts for 37 to 41 weeks. Week 1 - 2: The first week of pregnancy is from the first day of a woman's menstrual cycle and she is not considered pregnant yet. - At the end of the second week, the egg is secreted from the ovary, and this is at the most likely time for pregnancy if sexual intercourse takes place without contraception. Week 3: sperm. During sexual intercourse, after the man ejaculates, sperm enter the vagina. ...

Roman Emperor Nero: Information and Facts.

 Nero became Emperor of the Roman Empire after the death of his adoptive father, Emperor Cladius, in AD 54. Nero was the last ruler of what historians call the "Julio Claudian" dynasty, and he ruled until his suicide in June 68 AD. Nero is best known for his story of playing the violin while Rome burns in a wild fire, but in fact this story is questionable. Nero is one of the most notorious men in history. During his reign he killed his mother Agrippina the younger and his first wife Octavia, and allegedly killed his second wife, Poppaia Sabina. In addition, ancient writers claim that Nero was the one who started the great fire of Rome in 64 AD in order to rebuild the center City. Although ancient writers drew many accusations against Nero, the evidence indicates that he enjoyed some popular support, as he was so passionate about music and the arts that he performed a public musical in Rome in AD 65. Suetonius, a critic of the second century A.D., wrote: "Nero missed any...

8 signs of vitamin deficiency you should know.

 Eating a balanced and nutritious diet has many benefits, while a diet that is poor in nutrients leads to a number of symptoms, which is the way your body reacts to a deficiency of vitamins and minerals, and recognizing them helps to adjust the appropriate diet for you. This article reviews the 8 most common signs of vitamin and mineral deficiency, and how to treat them. 1. Fragility of nails and hair Several factors may cause hair and nails fragility, such as a deficiency of biotin, or vitamin B7, which helps the body convert food into energy. Biotin deficiency is very rare, but if it occurs it causes hair loss and nail breakage. Other symptoms of biotin deficiency include: chronic fatigue, muscle pain, and cramping and tingling in the hands and feet. Risk factors include: pregnancy, smoking, heavy drinking, Crohn's disease, prolonged use of antibiotics and some anticonvulsant drugs. Eating raw egg white causes a lack of biotin, because it contains avidin, a protein that binds to ...
