Завдання 4. Перегляньте текст, після чого заповніть пропуски в

нижченаведених реченнях відповідною інформацією.

Matter is simply defined as that which occupies space. Matter is constantly

undergoing changes. These are: (I) physical changes which do not affect the

composition of matter and (2) chemical changes which do affect its composition. The

substances taking part in chemical changes are defined as chemical compounds or

elements.

Chemical compounds are substances which are homogeneous throughout their

masses and which cannot be separated by mechanical means. They are combinations

of fundamental substances called «elements».

Elements are those substances which resist all attempts at furtherdecomposition.

The elements have been given values based on the relative by combining

weight, using hydrogen as a unity, which values are known as atomic weights and

which permit the calculations of the weights of reacting substances and the products

formed.

1. Matter is simply defined as that with осcupies space.
