Let's assume you are given two glass jars. Jar #1 has 32.07 g of sulfur and Jar #2 has 112.4 g of cadmium (Cd). Which beaker contains the greatest number of atoms? Choose the best answer. a. Jar #1 because one sulfur atom weighs less than one cadmium atom so you need more of the sulfur atoms to fill the jar. b. Jar #1 because it contains more moles of sulfur atoms than the number of moles of cadmium atoms...

3. You are given 90 mg of the following radioactively labeled carbohydrate, which contains a total of 3 uCi of 14C (14C = *). Draw the specific degradation pathway required to metabolize this molecule into a 3-Carbon subunit (pyruvate). Noting in this pathway we also incubated with a triose phosphate isomerase inhibitor (assume 100% inhibition). Specifically label the radioactive position(s) in the final product(s) and account for all radioactivity observed as this starting compound progresses through the pathway. Finally, calculate...

In this experiment you will use an oxidation - reduction titration to determine the percent of oxalate ion, CO2 in an unknown sample containing oxalate ion. Potassium permanganate (KMnO.) will be titrated against the oxalic acid (C2H:08) as shown by the following oxidation-reduction reaction: +3 +7 5C,044 2MnO4 + 16H* → 10CO, 8H0 + 2Mn2 +4 + + Mno. Mn? is the reduction process C2042 → CO2 is the oxidation process The underlying principle behind a titration is that an...
