- please do not give solution in image format thanku Refer to the graph below, showing surface area and volume as functions of body size. Because of the relationships shown in the graphNOTE: translucent (positive for fats) and opaque (negative for fats) To test for lipids, when we put one drop of corn oil on a paper towel (positive control): what opacity (translucent or opaque) did you observe in the paper towel? Does that mean the substance is present or absent? To test for lipids, when we put one drop of distilled water on a paper towel (negative control): what opacity (translucent or opaque) did you observe in the paper towel? Does that mean the substance is present or absent? What is the purpose of having controls when testing for lipids in this experiment?D5 Please answer the question and write the chemical equation, thanks.
- Subject: chemistryTwo students plan and carry out an investigation to determine if ionic or covalent bonds have stronger intermolecular forces. They collect the following data. C6H1206 NaCI color white white texture,grain size rough, small pieces rough, very small grains solubility in water soluble (able to dissolve) soluble (able to dissolve) melting point melts easily does not melt a. Identify the type of intramolecular bonds that are involved. b. Which substance will have the stronger intermolecular forces? c. Which properties allow you to predict the strength of the intermolecular forces? Format B I U ... >STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP =0°C, 1 atm, where the molar volume = 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the molar volume is 22.7 L/mol. Do not confuse the two. A 0.99 mol sample of hydrogen gas occupies a volume of L at STP.
