Of helium?a) Identify the following as element (atomic or molecular), compound or mixture. b) Explain your reasoning and draw a sample of these substances containing 5 particles of that particular material. c) What would be the mass of 5 particles of that particular material? Show your work! H20 N2 C2HSOH Iodine gasIn addition to solid, liquid, and gas, we also have plasma. Plasma, the "fourth state," is characterized by lack of shape, and it cannot be classified as gas, liquid, or solid. Examples of plasma are plasma ball and the contents of a fluorescent bulb. The fifth state has already been discovered by scientists. It is called Bose-Einstein Condensate (BEC), but in Grade 3, the focus of study is only on the three states of matter: solids, liquids, and gases. Let us have some exercises on grouping of matter.
