Water has a number of unique properties that sets it apart from other substances, sometimes called the "anomalies of water." The most commonly recognized anomalies are:
Pick 1 of these properties and learn more about how it can be explained from the viewpoint of attraction forces between molecules and/or other physical properties of water, as well as the significance of these properties for life on earth.
Based on the information you have learned, write a thread about 1 of the anomalies, referencing your sources and address the following points:
When 5.00 g of fructose, C6H12O6, (FW 180.16 g/mol) is burned in a calorimeter whose heat capacity is 29.7 kJ/oK, the temperature increases by 2.635oK. Calculate the heat of combustion of fructose in kJ per mole.
If the reaction 2H2S(g) 2H2(g) + S2(g) is carried out at 1065C, Kp = 0.0120. What is the value of Kc for the reaction H2(g)+1/2S2(g) H2S(g) at 1065C ?
The titration of 0.7910 grams of an unknown weak acid requires 41.5 mL of 0.139 M NaOH in order to reach the equivalence point.
Because of the movable plunger on a syringe, the gas inside the syringe can be held at a constant pressure of 1.00 atm while allowing the volume of the gas to increase or decrease.
Explain how size exclusion chromatography operates and how it could be used to isolate a protein with a molecular mass of 27,000 from an aqueous mixture of small molecules and salts.
