The typical estimation of Zeff only counts core electrons as shielding electrons. For a more accurate estimation of Zeff, the other electrons that are not core electrons also have to be considered. These electrons also contribute to shielding, but not to the full extent as core electrons and can be estimated as a shielding of 0.35 each. For example: what is the effective nuclear charge of a valence electron in C

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
