2. Soaps (surfactants) are amphiphilic, meaning they have both polar and nonpolar domains. For example, when you use Dawn dishwashing soap to clean dishes, the main molecule in the soap, sodium dodecyl sulfate (SDS), will form a foam as you scrub. Let's imagine the simplified scenario in which we only have SDS, water and air. Draw how the You can use the SDS molecule will orient itself at the air-water interface following simplified diagram to represent SDS. hydrophobic air water hydrophilic

4. Why do you determine a mass by difference? You use this because it's typically more accurate. 5. What are equivalence points and end points? How do they differ? equivalence point- the point @ which stoichiometric quantities are brought together, end point- the the equivalence point is theoretical, when end poi 6.

Sodium glutamate (commonly known as monosodium glutamate, MSG) is a salt found in seaweed that is used to enhance savory flavors, with a molar mass of 169.11 g/mol. Research has shown the ideal flavor profile for a soup is reached at 0.0856 M sodium glutamate. How many grams of MSG should be added to 2.44 L of soup to reach that concentration? g

1. A class organic compounds containing a six-membered ring with alternating double bonds that results in delocalization of the electrons within the ring. This class of compounds can have additional groups attached to the ring. 2. A family of organic compounds that can be represented by the general formula R-CHO. 3. A compound with the general formula R-COOH. It is a weak electrolyte that can lose an H+ ion in water solutions. 4. A hydrocarbon with a general formula of CnH(2n+2). All carbon-to-carbon bonds would be single bonds.

In class we are learning about solubility, electrolytes both strong and weak. I totally get it. I just want to review how the notation of polar covalent soluble nonelectrolytes work. For example, Glucose as a solid being dropped in a water solution. Even though it is not ionic, it is very soluble and does not break up, so is not a electrolyte. Like an Ionic soluble, it does get hydrated. Thus , by thjs logic should it be notated like this? Glucose (s) >>>>>>>> Glucose (aq) ??? Or is there some other notation for sugar solution?
