2. Predict the order that the following proteins will elute from a CM Sephadex column run at pH 6.5 using a NaCI gradient: fibrinogen (pl-5.8), hemogloblin (pl7.1), ribonuclease A (pl7.8), lysozyme (pl-11), pepsin (pl-1.0) 3. In the laboratory we ran an immunoblot on fractions obtained from the alkaline phosphatase experiment. This procedure requires a number of steps, two different antibodies and a detection method. You should be...

5. One group of students in an int arguing that the pressu aroup of students in an introductory chemistry course is arguing that the pressures of a con- Chudrogen gas and a container of sulfur dioxide gas, under the following conditions, cannot equal. Both containers are sealed, with equal volume, at the same to that the pressures cannot be equal because a sulfur dioxide molecule has a much larger han diatomic hydrogen, and therefore exerts a much greater force when...

Synthesis using Carbonyla-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...

5. A student carries out a calorimetry experiment using HCl and NaOH. What effect will each of the following have on the calculated enthalpy of the reaction relative to the actual enthalpy of reaction? (larger, smaller or no change). Explain your reasoning a. The thermometer always registered a temperature 0.30 °C higher than the actual temperature b. The calorimeter constant used in the calculations by the student is larger than the actual value.
