Cheat Sheet

Formula Cheat Sheet a tear-out page preceding this introduction that lists important formulas from the chapters. 

Now that you know when you have time available, you need to use that time to your best advantage. You will probably find that you can set aside one block of time during the day during which you will do the bulk of your studying. Use this time to learn new material or take a practice quiz and review your answers. Use the small spurts of time you have found in your schedule to review with flashcards, cheat sheets, and other tools. 

Personalize your cheat sheet. Of course, you aren t really going to cheat, but take the Formula Cheat Sheet found on page ix and add to it. Or, highlight the formulas you really need and don t yet know well. This will help them to stand out more than the ones you already know. You can then use the sheet to review—perfect for studying on the go.

In addition to the topics we cover in this book, you can find even more information online. The Cheat Sheet at www.dummies. com/cheatsheet/chemistrywb provides some quick and useful tips for solving the most common types of chemistry problems you ll see. If you d like to pick up some chemistry-specific study tips, find out more about solid-state chemistry, or see a valuable alternative to determining concentration in molcirity, go to WWW.dummies.com/extras/chemistrywb.

When solving a quadratic equation of the form ax2 + bx + c = 0, you either factor the expression and set the factors equal to 0 to solve for x, or you use the quadratic formula. (You ll find the quadratic formula in the Cheat Sheet.)... 

The expansion of the binomial (n + l)3 results in a polynomial where the coefficients of the terms have a distinctive, symmetric pattern. Refer to the Cheat Sheet for some of the other powers of a binomial. You ll see that the cube of (n + 1) has coefficients in the 1-3-3-1 pattern. 

You end up with a quadratic equation. You can factor the equation or you can use the quadratic formula. (See the Cheat Sheet for the formula.) I show you factoring, in the following equation, after multiplying every term by 2 so that the coefficient of the x2 term becomes a 1. 

If you had a positive pregnancy test before you started transforming, the following cheat sheet can help you catch up quickly. 

The periodic table (Figure 1.1) has been called the chemist s cheat sheet because of the amount of information it provides. Look at the square that has the letters Ca in it. The first letter for an element is always capitalized, and the second letter, if there is one, is lowercase. Notice that there are two numbers in the square. The smaller of the two is the number of protons (the atomic number). It is also equal to the number of electrons. The larger number in each square in the periodic table is the mass number of the element (the sum of the protons and neutrons). For our purposes, this mass number should be rounded to the nearest whole number. For example, the larger number in the block for Br (bromine) is 79.9, and we will round this off to 80.

As you build your SIPOC Map, you can use the "cheat sheet" shown in Exhibit 45.1 to guide your answers. 

Perhaps the most interesting thing about the Periodic Table of Elements is how much information is hidden in it. To the untrained eye, the periodic table appears to only show the elemental symbols, elemental names, atomic numbers, and atomic masses. However, someone who knows a bit more chemistry can squeeze much more information out of the same table. You will learn to use the periodic table to check your electron configurations, orbital notations, and Lewis dot notations. You will also learn to use the periodic table to check many relative properties of the elements, such as reactivity, electronegativity, and metallic character. All of this information is there, if you know how to use the table correctly. It is certainly in your best interest to learn as much about the periodic table as possible, because you are allowed to make use of it on many exams and quizzes. If you are able to extract all kinds of information from it, it becomes an incredibly useful cheat sheet, except that you re allowed to use it ... 

Memorizing those symbols is incredibly useful. But you don t have to do it. Instead, you can turn to the Cheat Sheet at the beginning of this book, where you can find a neat list of every symbol you need to know. The Cheat Sheet enables you to translate the symbols back into English. That way, when you re looking at a birth chart and you see something like this ... 

But what if you re outside the reach of a computer What if you re all alone on that mythical desert island, leaning against that palm tree, reading this book Using only the information contained here, you can construct a rough version of your horoscope (or anyone else s) — and for most purposes, that approximation will do just fine. First, copy the blank chart form on the Cheat Sheet, either by machine or — if that desert island doesn t happen to have a Kinko s — by hand. Next, follow the instructions in this chapter. 

Once you have identified your rising sign, your troubles are over. If you haven t already done so, go to the Cheat Sheet and make a copy of the blank chart. 

Now take a blank horoscope wheel like the one on the Cheat Sheet and assign Scorpio to the first house, Sagittarius to the second, and so on, as shown in Figure 3-2. Write the symbols for the planets (or their names) in the correct houses. If you re a beginner, you may want to do this in plain English, a process that yields a chart that looks something like Figure 3-3. 

Better yet, memorize the beautiful and mysterious astrological symbols. (The Cheat Sheet at the beginning of the book can help.) That way, you end up with a chart that looks like Figure 3-4. 

To follow your transits, make a copy of the empty chart on the Cheat Sheet and place your birth planet in the appropriate sections. (See Chapter 3 for more information on constructing your birth chart.) Then position the transiting...

In the calculations which follow, the equivalence of the additives, magnesium carbonate and sodium oxalate, as part of the overall equivalence of the base fire, is small and may be ignored. The simplest way to perform the adjustment exactly, would be to blend the mixtures of the additives and sulfur of the percentage composition given in the cheat sheet. In practice, this is rarely necessary, as so many other factors are used to vary the effect that small variations in stoichiometry are of small impact on the effect the star will produce. With this simplification the calculations for the mix become ...
