The centrifuging of substances is done to seperate the components having different densities.
The centrifuge tubes in the machine are spun at a very high velocity due to which the materials with higher density settle down at bottom and light materials form the top layer. The system must always be balanced with respect to mass during use because any imbalance in the mass may cause instability in the centrifuge. If it is run at low speed , it will wobble making a loud noise and may cause failure whereas at high speeds it may throw out the substance causing irrepairable damage to the system.

When aqueous lead (II) nitrate is added to aqueous potassium iodide, the brilliant yellow solid, lead (II) iodide forms (as well as aqueous potassium nitrate). Write out the balanced chemical equation for this precipitation reaction. According to the solubility rules provided in class, would you predict an insoluble precipitate, considering the two reactants added together? Why or why not? If 300.0 mL of a 0.10 M solution of each reactant is added together, how many grams of lead (II) iodide...

III. Silver-ammonia coordination complex What is the formula and name of the solid produced when you mixed sodium chloride and silver nitrate? Briefly describe what happens when ammonia is added to the solution of sodium chloride and silver nitrate. When ammola is a sodium chloride and siliver nitrate it took away the white solution w/ solid to clear Without solid, Give the balanced net ionic equation for the reaction with ammonia.

Why must we use a novel approach when we solve for equilibrium concentrations in formation reactions? None of these Large Kfvalues ensure that nearly all of the limiting reactant is consumed Formation reactions never really reach equilibrium, and instead stop when the limiting reactant is completely consumed Products of formation reactions are unstable and participate in many side-reactions Formation reactions tend to be exothermic, which normal ICE tables don't account for Oxidation numbers always change in formation reactions

1. During the extraction process, the protein samples must be kept on ice. Why? 2. What is the role of the bovine serum albumin (BSA) in this experiment? 3. Calculate the volume of BSA stock that will be required to make the standard solutions needed to create the BSA standard curve. Be sure to show your work and include the volume of 0.02 M phosphate buffer required to reach a final volume of 1 mL.
