Re: 2014 final #8

It is because the addition of NaOH puts in extra OH- concentration which leads to a higher pH.

Re: difference between k in pressure and k in concentration

You can change Kp to Kc and vice versa with the equation Kp = Kc(RT)^(delta n) but I believe that we are not going to be needing this equation for the class.

Re: When does the transition metal change to -ide?

The transition metals do not change their endings to -ide but will change to -ate in the case that the complex compound would be an anion ie: hexa-fluoro-cobaltate(III), otherwise it is simple the name of the metal if it is a cation. As for the position of the metal when writing either in nomenclatu...

Re: Polar vs Nonpolar

Polar molecules are simply molecules that has polarity as in there is a difference in the strength of the atoms in the molecules, ie: H2O is a polar molecules because the oxygen molecule has greater electronegativity than the hydrogen atoms which causes dipole moment that leads to what a polar molec...

Re: Rydberg Equation

I think that the Rydberg Equation itself can be used for any atoms. However, the constant for R would be different for all atoms so the only constant we know for sure is Hydrogen which is why its the only atom we used for the equation.
