Chemistry , the science that deals with the properties, composition , and structure of substances defined as elements and compounds , the transformations they undergo, and the energy that is released or absorbed during these processes. Every substance, whether naturally occurring or artificially produced, consists of one or more of the hundred-odd species of atoms that have been identified as elements.

Chemistry is the study of matter—what it consists of, what its properties are, and how it changes. Matter is anything that has mass and takes up space—that is, anything that is physically real. Some things are easily identified as matter—the screen on which you are reading this book, for example. Others are not so obvious. Because we move so easily through air, we sometimes forget that it, too, is matter.

Chemistry is a branch of science which deals with the study of matter composed of atoms and molecules, their properties, composition, structure, behaviour, and interactions among constituents of matter. Chemistry is a very fascinating subject. We all are surrounded by chemistry. Everything around us composes of atoms and molecules including our bodies itself. We can see chemistry in our day-to-day activities; right from the production of food in farms to cooking them in a kitchen, from a bicycle to a space rocket from phones to computers.

Chemistry and Its Branches

Chemistry is a scientific discipline that involves the study of matter, its compositions, properties and reactivity with other elements. Matter is something that has mass and acquires space. Everything around us that is physically present is made up of matter. For instance, books, furniture, and even our bodies. The basic concepts laid down in Chemistry is the foundation of matter ranging from atoms, molecules, compounds and the measuring units of matter. In the scope of its subject, Chemistry lies somewhere at the intermediate position between various other branches of science. This explains its importance to the rest of branches of science.

The five main branches of chemistry are organic, inorganic, analytical, physical, and biochemistry. But, there are many important sub-branches and types of chemistry shared with other disciplines. Here are the definitions and descriptions of the major branches, with a list of several other areas of study. Organic chemistry is the study of life and organic carbon compounds. This discipline focuses on compounds that contain C-H bonds. Inorganic chemistry studies inorganic compounds, including metals, ceramics, and minerals.

The five major branches of chemistry are organic, inorganic, analytical, physical, and biochemistry. These divide into many sub-branches. Organic chemistry involves the study of the structure, properties, and preparation of chemical compounds that consist primarily of carbon and hydrogen. Inorganic chemistry is the study of the properties and behaviour of inorganic compounds. Inorganic chemists study things such as crystal structures, minerals, metals, catalysts, and most elements in the Periodic Table.

Branches of Chemistry

The following outline is provided as an overview of and topical guide to chemistry:. Chemistry is the science of atomic matter matter that is composed of chemical elements , especially its chemical reactions , but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions. From Wikipedia, the free encyclopedia. Overview of and topical guide to chemistry.

You might think of chemistry only in the context of lab tests, food additives or dangerous substances, but the field of chemistry involves everything around us. So, even if you don't work as a chemist, you're doing chemistry, or something that involves chemistry, with pretty much everything you do. In everyday life, you do chemistry when you cook, when you use cleaning detergents to wipe off your counter, when you take medicine or when you dilute concentrated juice so that the taste isn't as intense.

What is chemistry?

 - Сюрреализм. Я в плену абсурдного сна. Проснувшись утром в своей постели, Беккер заканчивал день тем, что ломился в гостиничный номер незнакомого человека в Испании в поисках какого-то магического кольца. Суровый голос Стратмора вернул его к действительности. Вы должны найти это кольцо. Беккер глубоко вздохнул и перестал жаловаться на судьбу.

Все данные, свидетельствующие о том, кто чем владел, должны были исчезнуть навсегда. Поскольку для одновременного подрыва устройств была необходима точнейшая координация действий, все эти изделия были связаны между собой телефонными линиями через Интернет. Двое суток встроенные часы устройств обменивались бесконечными потоками зашифрованной синхронизирующейся информации. АНБ, перехватывая эти информационные импульсы, игнорировало их, считая аномалией сети, безобидной тарабарщиной.


Physical Chemistry. ▫ Studies the properties and changes of matter and their relationship to energy. How can a surface be made to better.


 Там подают отличный карпаччо.  - Хейл улыбнулся.  - Что скажешь. А потом мы могли бы… - Выкинь это из головы.

Я уверен. Вы должны… Сьюзан вырвала руку и посмотрела на него с возмущением. - Мне кажется, коммандер приказал вам уйти.

Если Стратмор получил от Следопыта информацию, значит, тот работал. Она оказалась бессмысленной, потому что он ввел задание в неверной последовательности, но ведь Следопыт работал. Но Сьюзан тут же сообразила, что могла быть еще одна причина отключения Следопыта. Внутренние ошибки программы не являлись единственными причинами сбоя, потому что иногда в действие вступали внешние силы - скачки напряжения, попавшие на платы частички пыли, повреждение проводов. Поскольку за техникой Третьего узла следили самым тщательным образом, она даже не рассматривала такую возможность.

Коммандер отпустил Сьюзан и повернулся к своему детищу стоимостью два миллиарда долларов. Глаза его расширились от ужаса. - Нет! - Он схватился за голову.
