Suppose that a linear Na11 molecule could be formed by combining the 3s orbitals on each atom into delocalized MOs. How many nodal planes are in the highest occupied molecular orbital (HOMO) of this molecule?
The heat of vaporization of liquid water is 40.67 kJ/mol, and the molar heat capacity is 75.3 J/(K*mol) for the liquid and 33.6 J/(K*mol)for the vapor.
A titration was performed to standardize an EDTA solution. use the following data to calculate the molarity of the EDTA solution. A 50.00 mL aliquot of a standard solution containing 0.025000 M Ca^2+ required 39.92 mL of EDTA to reach a distinct b..
The question in the lab is asking what percentage by mass is the calcium, chloride and water in the orginal solution for each trial. In this lab we performed two trials, in each, we added 50 mL water to 2.0 g of CaCl2.
