1 of 1 Part D-A typical enzyme experiment A common enzyme studied in many introductory biology labs is catalase, which is found in high concentration in most cells, promoting the decomposition of hydrogen peroxide (H2O2) Hydrogen peroxide is formed as a by-product of chemical reactions and would soon kill cells if not immediately removed or broken down into its products--water and oxygen-as shown by the following equation Catalase 2 H2O, → 2 H2O + 0, You may be familiar with...

4. Approximate the number of moles of hydrogen peroxide at the equivalence point in the graph in the introduction, supposing a 3.00% m/m solution. Thus the densities will be- Trial Mass(g) 0.448 0.450 3 Density(g/ml) 0.448 g/ 0.400 ml = 1.12 g/ml 0.450 g/ 0.400 ml = 1.125 g/ml 0.437 g/ 0.400 ml = 1.0925 g/m 0.442 g/ 0.400 ml = 1.105 g/ml...

Question 1 A Chem 2111 student in a gravimetric analysis experiment analyzed an iron ore by dissolving a 1.1234 g sample in concentrated HCl solution. After dilution with water, the iron(III) in the sample was precipitated as Fe2O3.xH2O by addition of ammonia NH3. After filtration, washing and drying, the precipitate was isolated to produce 0.5394 g of pure Fe2O3. a) Calculate the weight percent of iron Fe in this sample. b) Calculate the weight percent of magnetite Fe3O4 (rock mineral)...

Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...
