f PCl3 . For each orbital, identify if the interaction is of bonding or anti-bonding character, is it of the sigma or pi type. Explain how each of the molecular orbitals are formed, indicate which atomic orbitals contribute to each molecular orbital, take into account the phases that each orbital can present. How much energy is required to ionize one mole of each chemical species?
iment in which 36.6 grams of BeSO4 is needed, but the only jar of reagent in the lab is labelled beryllium sulfate tetrahydrate. How many grams of the hydrate must the student weigh out in order to get the desired amount of the anhydrous compound?
entahydrate. My students are varying either the mass of the copper oxide or the concentration of the sulfuric acid. They do not have an understanding of any chemistry calculations and only basic knowledge about chemical equations. They should have some knowledge of ionic equations and neutralistions reactions but I need to explain it to them in very basic terms. Without doing any calculations myself I can't explain it to them.
ow. I'm not sure how to calculate this.
Prepare five 25mL solutions of acidified potassium dichromate from a stock solution of 0.010M K2Cr2O7in 2.0 M H2SO4 with the concentrations
and 0.0040 M.
