This organic chemistry video tutorial explains how nucleophilic substitution reactions work. It focuses on the SN1 and Sn2 reaction mechanism and it provides plenty of examples and practice problems. The Sn2 reaction is a second order nucleophilic substitution reaction where the rate is dependent on the concentration of the substrate / alkyl halide and the nucleophile. SN2 reactions occur with inversion of configuration and work well with methyl and primary substrates. It's a concerted reaction mechanism that occurs in a single step. The rate law for the SN1 reaction is given as well. SN1 reactions proceed via a carbocation intermediate and carbocation rearrangements such as the hydride shift and the methyl shift are possible. SN1 reactions work well with tertiary alkyl halide substrates due to carbocation stability. Carbocations are stabilized by means of hyperconjugation and the inductive effect. SN1 reactions will produce an unequal racemic mixture. The stereochemistry of both reaction mechanisms are discussed in detail. SN1 reactions work well with polar protic solvents but SN2 reactions work better in polar aprotic solvents. Solvolysis reactions are sn1 reactions where the nucleophile is the same as the solvent.

This physics video tutorial provides a basic introduction into torque which is also known as moment of force. Torque is the product of force and lever arm also known as moment arm. The lever arm is the perpendicular distance between the axis of rotation and the line of action of the force. Torque is the rotational equivalent of force. Positive torque values produce counterclockwise rotation and negative torques produce clockwise rotation. This video contains plenty of examples and practice problems of torques as it relates to doors, seesaws, and shovels. It discusses how to calculate the mechanical advantage of simple machines like seesaws and shovels.

This organic chemistry video tutorial provides a basic introduction into drawing resonance structures. It explains how to identify the major resonance contributor as well as the minor resonance contributor based on stability. Here are a few key concepts to keep in mind: Negative charges are stabilized by electronegative atoms. Neutral resonance structures are more stable than those with separation of charges. Tertiary carbocations are more stable than secondary and primary carbocations due to the inductive effect and hyperconjugation. Positive charges on carbon atoms are not stable due to the octet rule.

The 68 - 95 -99.7 Rule (Empirical Rule) lets us know approximately what percent of the normal distribution exists between the first, second, and third stand deviation of the mean, respectively.

Combining this information with the fact that the normal distribution is symmetric about the mean, we can calculate the percent of the distribution that falls between each standard deviation. This video reminds you how to come up with these percentages on the fly if all you can remember is the 68 - 95 -99.7 Rule (Empirical Rule).

Some images made using Geogebra.

0:00 Introduction
0:25 Percent between first standard deviation of the mean
0:57 Percent between second standard deviation of the mean
1:35 Percent between third standard deviation of the mean
2:01 Percent in tails to infinities

The end behavior of a polynomial tells us the direction a function goes as x approaches positive or negative infinity. Using just the coefficient and highest power of a polynomial we can determine the end behavior.

1:48 The four types of polynomial end behaviors

Finding the y-intercept of a function is easy if you are given the graph, but how do you find it if you are given only a function in a single variable?

Sometimes, you are asked to make sure all of the exponents in your answer are positive. To convert any exponent from negative to positive you either move the variable from the numerator to the denominator or you move the variable from the denominator to the numerator. You may have heard this rule called the elevator rule, because you can imagine the variable hopping into an elevator and moving up or down one floor.

The rule is:

x^(-n)=1/x^n
or
1/x^(-n)=x^n

What Is Checkmate? | Definition and Meaning | Learn to Play Chess

The most important word associated with chess is checkmate. It is how a player either wins or loses the game. Therefore before you explain the other rules of chess to kids, start with the most basic knowledge of checkmate, so that they know what they need to know in order to win the game.

You know about CPR, capture protect runaway. If the king cannot get out of CPR situation it means checkmate. In simple words, if the king is being attacked and it cannot save itself in any way we say its checkmate and the game is over.

Since in chess we do not capture the king so checkmate means that it is the turn before we would capture the king, which simply means the king is trapped and there is no way out.

Let me explain this through the example above.

In this position, the queen is at b7 attacking the black king. The black king cannot protect or run away from here. However, the king can do a capture move from here.

The black king can easily capture the queen from here and save itself from checkmate.
However, if we make little changes in the arrangement of this board.

Now the black king has no place to run away, neither can it protect itself nor it can capture the queen. Because now the queen is being protected by the white king. Therefore there is no way that the black king can now attack the queen. This brings the black king in a checkmate situation. Now there is no way that it can save itself. Hence now this would be called a checkmate and it is game over.

You can set many different examples on your chess board to better explain the concept to the kids to make it more interesting for them. This online chess session is extremely helpful for kids and can be used as chess lessons for beginners.
