1.1: The Scope of Chemistry
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 , 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. Although these atoms, in turn, are composed of more elementary particles, they are the basic building blocks of chemical substances; there is no quantity of oxygen , mercury , or gold , for example, smaller than an atom of that substance. Chemistry, therefore, is concerned not with the subatomic domain but with the properties of atoms and the laws governing their combinations and how the knowledge of these properties can be used to achieve specific purposes. Chemistry is the branch of science that deals with the properties, composition, and structure of elements and compounds , how they can change, and the energy that is released or absorbed when they change. Chemistry is the study of substances—that is, elements and compounds —while biology is the study of living things.
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.
The 5 main branches of chemistry are organic, inorganic, analytical, and physical chemistry. The five main branches of chemistry are organic, inorganic, analytical, physical, and biochemistry.
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.

Слева и справа от алтаря в поперечном нефе расположены исповедальни, священные надгробия и дополнительные места для прихожан. Беккер оказался в центре длинной скамьи в задней части собора. Над головой, в головокружительном пустом пространстве, на потрепанной веревке раскачивалась серебряная курильница размером с холодильник, описывая громадную дугу и источая едва уловимый аромат. Колокола Гиральды по-прежнему звонили, заставляя содрогаться каменные своды. Беккер перевел взгляд на позолоченную стену под потолком.
Господи Иисусе! - вскричал Джабба. - Откуда нам знать, что для Танкадо было главной разницей. - На самом деле, - прервал его Дэвид, - Танкадо имел в виду первичную, а не главную разницу. Его слова буквально обожгли Сьюзан.
Он не знал, как зовут этого человека. - Deutscher, ja. Вы немец.
