chemical compound的意思|示意

Chemical Compound，中文意思是化合物，是物质由两种或两种以上不同的化学元素组成的物质，元素的结合类型不同也称为化合物。

Chemical compounds can be used to identify a substance. A chemical formula is used to represent a chemical compound, which displays the number of each element present as subscripts to the chemical symbol of the element. For example, the chemical formula for water is H20, which means it is composed of two elements—hydrogen and oxygen. This knowledge can help scientists to identify a substance, as the chemical formula indicates what kind of elements it contains and their ratios.

Chemical compounds can also be used to make chemical reactions. Chemical reaction is a process whereby a substance is broken down into smaller particles or two or more substances are combined to form a new product. This process usually involves a rearrangement of atoms and this rearrangement requires energy. Chemical reactions are also used to create products such as medicines and fertilizers.

Finally, chemical compounds can be used to indicate the type of reaction that takes place. Chemical reactions are generally characterized as either being endothermic or exothermic. When an endothermic reaction occurs, energy is absorbed from the surroundings while in an exothermic reaction, energy is released. Knowing the type of reaction allows scientists to predict the energy changes that will occur and to plan the conditions needed for the reaction to occur.

Chemical compounds are an important part of the study of chemistry and are used in many aspects of life. Knowing how to identify, understand and use them is essential for any chemistry student.
