In the table below you will find three descriptions of scientists engaging in activities that are part of the scientific method. What are the missing words? missing word? description Antoine burns some charcoal, and a very small diamond (1), and makes that the only product of both reactions is a heavy gas the (carbon dioxide). After studying the chemical reactions of many compounds made of carbon, August discovers a that says carbon always forms 4 chemical bonds to other atoms when it forms a compound. Dmitri discovers that the known chemical elements can be arranged in a pattern of columns and rows, with elements in the same column behaving similarly. But there is no element at a certain place in the pattern, and Dmitri proposes the that an unknown element fits into that spot, and that it will have properties similar to the elements above and below it in the pattern. 0 0 0 5 ?
