Перегляньте текст, після чого заповніть пропуски внижченаведених реченнях відповідною інформацією.Matter is simply defined as that which occupies space. Matter is constantlyundergoing changes. These are: (I) physical changes which do not affect thecomposition of matter and (2) chemical changes which do affect its composition. Thesubstances taking part in chemical changes are defined as chemical compounds orelements.Chemical compounds are substances which are homogeneous throughout theirmasses and which cannot be separated by mechanical means. They are combinationsof 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 combiningweight, using hydrogen as a unity, which values are known as atomic weights andwhich permit the calculations of the weights of reacting substances and the productsformed.1.
