Please do question 3 if you can do 4 that will be awesome 2. Water is made of two elements, hydrogen, and oxygen. What possible elements couldsubstitute for each of those elements?Theoxygen can be substituted by the sulfur. Hence, H,0 can be replaced by the H,S.3. Of these, which combination of elements do we think would make a compound mostsimilar to water and why?WHAT PROPERTIES SHOULD WE LOOK FOR?4. What compounds are we investigating?5. What are the properties of water that make it important for life? The substances that weare investigating need to have similar properties if they are to be good substitutes for water.Property:Why it is Important for Life:Water is called the universal solvent because many substances dissolvein water than any other solvent. This is due to the polarity of watermolecules.Universal solventBoiling and freezing Due to the presence of Hydrogen bonds in water molecules. Itrequires more energy to break its hydrogen bond. Thus possess ahigh boiling point (100c). This is important for aquatic species and topointsthe environment also.if water is easily boiled or freeze, then anyHin and aouatic

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…
