C08-0024. From the location of each element in the periodic table, predict which ion of each of the following elements will be found in ionic compounds Ca, Cs, Al, and Br. 

C08-0081. Refer to the lattice energy values in Table Predict the lattice energy of MgS, and explain your prediction.

C21-0042. From Its position in the periodic table, predict the properties of thallium (Element 81). 

We note that the 5d subshcll started before the 4/ subshcll, but only one electron entered that shell before the 4/ subshell started. Indeed, the periodic table predicts this correct configuration for Gd better than the n + I rule or other common memory aids. 

Three projects (A, B, C) all earn a total of 125,000 over a period of 5 years (after-tax earnings, nondiscounted). For the cash-flow patterns shown in the table, predict by inspection which project will have the largest rate of return. Why ... 

After you ve taken the multiple-choice practice exam under timed conditions, count the number of questions you got correct. From this number, subtract the number of wrong answers x A Do not count items left blank as wrong. Then refer to this table to find your probable overall AP score. For example, if you get 39 questions correct, based on historical statistics you have a 25% chance of receiving an overall score of 3, a 63% chance of receiving an overall score of 4, and a 12% chance of receiving an overall score of 5. Note that your actual results may be different from the score this table predicts. Also, remember that the free-response section represents 55% of your AP score. 

The molecular ion regions of the chemical ionization mass spectra of 37 2 and 37 3 are listed in the table. Predict the expected intensities of M, M+1, and M+2 for each of the four species listed. Include contributions from C, H. O, and N, as appropriate. Compare your predictions with the observed values. Discrepant intensities in these data are typical unless care is taken to obtain high-quality data. 

The chemical behavior of the transuranium elements is interesting because of its complexity and the insights offered into the chemistry of the lighter elements. The placing of these manmade elements into the periodic table (Fig. 15.1) represents one of the few significant alterations of the original periodic table of Mendelyeev. Since so little is known about the chemistry of the transactinide elements, one has the unique opportunity to test periodic table predictions of chemical behavior before the relevant experiments are done. 

Without consulting entropy tables, predict the sign of AS for each of the following processes ... 

The predicted values for AHf° and S° for various coals are shown in Table II. In this Table, predicted and observed values of heat of combustion for the coals are also shown, where the former was calculated by the predicted value of AHf°. It is found that predicted values of heat of combustion agree well with observed ones. For S°, on the other hand, methods of this work (14) and of Cheng et al. (9) yield comparable results. 

Feasibility predictions on the basis of thermodynamic properties can be illustrated by the example of an inclined billiards table with a large number of balls on it. We assume that the balls can move with very minimum friction and very small loss of momentum on impact. Let us also assume that the balls at zero time are in motion uniformly all over the table. By laws of mechanics, it is possible to predict the position of the balls after lapse of different amounts of time. But by common-sense, we know that, after we allow substantial time, the balls will tend to concentrate on the lower area of the inclined table. Predictions of feasibility by thermodynamic laws are of the latter type. And why not, since Thermodynamics is based on common-sense. 

Using only the periodic table, predict the most stable ion for Na, Mg, Al, S, Cl, K, Ca, and Ga. Arrange these from largest to smallest radius and explain why the radius varies as it does. Compare your predictions with Fig. 13.7. 

There have been some predictions that element 114 will be relatively stable in comparison with many other elements beyond uranium in the periodic table. Predict the maximum oxidation state of this element. Based on the trends in the oxidation states of other members of its group, is it likely that this oxidation state will be the dominant one. ...
