How To: Make glow sticks with DEP, TCPO, sodium acetate & dye

If you prefer glow sticks over candles during a power outage, then this how-to is for you! Although glow sticks are used as temporary light sources, there are other applications for them. Divers use them for night diving, fisherman use them to catch swordfish, and the military uses them for light markers, along with infrared versions used in conjunction with night vision devices. But with all these handy uses for glow sticks, the most popular is — recreational use, like dancing at raves, some...

How To: Calculate weight average atomic mass of an element

In Chemistry weight of some elements are measure in the form of Average Atomic Mass. Isotopes are found in different abundances in nature. Certain elements have many isotopes and certain elements have few isotopes. Regardless of the number of the natural isotopes, the weighted average mass takes into consideration not only the mass of each isotope, but what also its natural abundance in terms of percent as found in the nature. So when you have the mass of two isotopes of an element and are gi...

Walkthrough The Saboteur: Act 2, M2: Better Dying...

You may have to eventually abandon your stealthy approach in this mission on The Saboteur for the Xbox 360. The second mission in Act 2: Better Dying Through Chemistry is when you reach the entrance, there's a gunner behind sandbags by himself. If you take him out quickly and disguise yourself you can actually play this level pretty quietly. There are two basic kinds of targets, the smaller, thinner tanks, and the bigger, darker tanks. The big tanks you can blow with dynamite and as long as y...

How To: Freeze a beaker to wood

Chemistry can be very fun when you create different kinds of reactions between elements. Note that caution should be employed to not harm yourself while performing these reactions. Ammonium Tricynate reacts with barium hydroxide octahydrate in endothermic form. Endothermic reactions are those which absorb heat from the surroundings during the reactions as opposed to exothermic reactions which produce a lot of heat during the reaction. When endothermic reaction occurs, depending up on the inte...

How To: Balance chemical equations properly

How To: Make a quartile diagram (aka, box and whisker plot)

This is an interesting mathematical instructional video on how to make a quartile diagram. This example is about 34 grades obtained by chemistry class students. We need a minimum value, a maximum value, Q1, Q2 and Q3 values to make a quartile diagram. The minimum is 43 and the maximum is 92. To calculate Q2 median formula (n+1 over 2)is used. The Q2 median is 17.5. So the average of 69 and 71 is 70 and hence Q2 70. Similarly Q1 is calculated as 61 and Q3 is calculated as 79. Now you can draw ...
