- The research group has recently focused on identifying the chemical properties of fluorocarbons, such as CF4 and C2F4. These fluorocarbons display a very different reactivity compared to hydrocarbons. Teflon (C2F4)n is a fluoropolymer. When Teflon is mixed with silica at high temperature, all solid decomposes into gases. Write down the reactions that can take place during the process and explain your reasoning.Your roommate, a history student, has stumbled across nitrogen trifluoride in their history textbook because it was used in the 1960s and 1970s as rocket fuel oxidizer. They remember learning about chemical reactions in Grade 11 and want to make nitrogen trifluoride using nitrogen gas and fluorine gas. Since you are a chemistry student, you have decided to help them remember how to construct the formula. Your other roommate, who is a mathematics student, wants to create a hypothetical situation so that the history student can better understand the concept. She writes down a mass for fluorine gas and nitrogen gas. 1. If she wrote that the mass of nitrogen gas as 114.6 g and the mass of fluorine gas as 354.8 g which is the limiting reagent in this case? 2. The mass of nitrogen trifluoride produced that she wrote is 469.4 g. What is the theoretical mass of nitrogen trifluoride produced calculated using the given masses? Is this higher or lower than the mass that she wrote? 3. If it is…Because carbon and silicon are both elements in group 14 on the periodic table, we expect them to react with other elements in similar ways. To some extent, they do, but in some cases, carbon and silicon compounds that seem to have analogous structures have very different chemical characteristics. For example, carbon tetrachloride, CCl4, is very stable in the presence of water, but silicon tetrachloride, SiCl4, reacts quickly with water. The unbalanced equation for this reaction is SiCl4 + H2O → Si(OH)4 + HCl Balance this equation. Write a conversion factor that could be used to convert between moles of SiCl4 and moles of H2O. How many moles of SiCl4 react with 24 moles of water? Write a conversion factor that could be used to convert between moles of Si(OH)4 and moles of water. How many moles of Si(OH)4 form when 4.01 moles of H2O react with an excess of SiCl4?

Enumerate some of these products and give the gaseous products of the chemical reactions when they explode. Is the prohibition of its manufacture justifiable? Does the danger to life and properties outweigh the economic advantages of outlawing these products? Why?doug began preparing laboratory surface disinfectant from chlorine bleach. he put on a chemical resistant apron and gloves and then removed the bleach container from the special chemical cabinet. he carefully placed the container on the laboratory benchtop and began to add the chlorine bleach to distilled water. nearby workers began complaining of burning eyes. doug was reprimanded by the supervisor.
