You don't have to sit on the floor, you can sit on the floor or anywhere the spine is straight. Sitting straight helps you connect with your body. You can also use the hand mudra which will help you create a pressure point and calm the nervous system down. Another tool is chanting or music which will change the ch...
In chemistry you come across problems which ask you to find the percent by mass and percent composition of each element in a chemical compound. To do this the first step is to compute the molar mass. Use the periodic table to look up the mass of individual atoms and multiply it by the number of atoms to find the mass of that element. Now add up all the masses to arrive at the molar mass of the compound. Now to find the percent composition of an element divide the total mass of each element by...
This video shows you how to calculate the percentage yield in chemistry. To find the percentage yield, you will need to divide the actual yield by the theoretical yield. Then, multiply it by 100: i.e. % yield = actual yield/theoretical yield x 100. An actual yield is the amount of a substance produced in an actual laboratory experiment. It is based on an actual physical measurement of a quantity. The theoretical yield is the yield as is calculated on paper: i.e. through calculations. Therefor...
This video shows you how to convert temperatures from Fahrenheit(F) to Celsius(C). In the video, the example of 75 degrees F is used. The formula for converting Fahrenheit to Celsius is given by temperature in Celsius= (temperature in Fahrenheit- 32)/1.8. So for 75 degrees F we take 75 in place of temperature in Fahrenheit. Therefore the equation becomes (75-32)/1.8=C . Further 43/1.8=c and finally C= 24. Hence 75 degrees Fahrenheit= 24 degrees Celsius . This conversion is used as Celsius is ...
This video is based on a chemistry experiment. This video is going to explain to us how to use gravimetric analysis in order to analyze sulfuric acid. This experiment should not be done for those who do not have a fundamental knowledge of chemical compounds, reactions and chemical safety. He explains first what he is about to do before he does it. Sulfuric acid is acidic and can be toxic if ingested or in contact with the eyes. Take extreme care with this experiment.

This is how to make a Kugel. Get out your eggs, noodles, sour cream, cottage cheese, sugar, and fruit salad. This is a classic kosher Passover treat or dish for any Jewish holiday.
This is how to make a near professional grade lava lamp. We did this as a chemistry project. We perfected it in a week. This took many hours to do, as we had to get the density just right. We remade it three times, also. At the very end, we combined all of the wax into a huge flask. And then it blew up.
Back when we took chemistry, most of what we read and learn went in one ear and out the other. If only we had a cool experiment like this one to perk up our pubescent ADD.
You've manage to get your hands on some ruthenium, and now you want to destroy the hard silvery-white metal of the transition series. Well, you're going to try all kinds of ways to dissolve this odd metal, but the only successful way to dissolve ruthenium is with a common household cleaner… bleach.

"You can never know too much" is a saying you hear all the time. Funny thing is, I have no idea where it originated, and neither do most of the people who continually say it. Nevertheless, it's a statement that very few would argue with.
The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder! Being able to make homemade gunpowder without a trip to the store can be a lifesaver, no matter if it's just for testing out a Civil War-era musket, blowing up stubborn tree stumps, or preparing for battle when imperialists overrun your country.
Foodies and big-time chefs like Thomas Keller go crazy for fleur de sel. This finishing salt appears in fancy eateries and cookbooks the world over, and in the early 2000s, it was not uncommon to see diners in a high-end restaurant sprinkle a pinch of fleur de sel on their plates from their own personal stash.
In this video, I'll be demonstrating how anyone can make their own iodine clock reaction with simple over-the-counter chemicals.
If you want to convince your friends that money is not an issue, then you can just burn it for real like Walter White. But if you don't really want to destroy your hard-earned cash, this burn trick is perfect for you. It just takes some basic chemistry and a few materials, such as salt, water, alcohol, tongs, and a source of fire. And of course—money.
Sodium (chemical symbol Na) is an interesting element. It reacts in contact with both oxygen and water, and several sodium salts are used to produce a yellow color in fireworks.
Home chemistry is great, but what happens when you forget to label your chemicals? How do you know if you turned a clear glass of ammonia into a clear glass of unobtainium? Chemists have a tool for just that.
I feel like doing a bit of chemistry today, how about you? To my knowledge, thermite is the hottest burning man-made substance. Thermite is a pyrotechnic composition of a metal powder and a metal oxide that produces an exothermic oxidation-reduction reaction known as a thermitereaction.
If I were to write a snickerdoodle FAQ list, the top question would undoubtedly be "Do I really need to use cream of tartar in my snickerdoodle cookies?"

Whether you are just starting or returning to college, or have already been out in the real world for some time, it's always a good idea to stay on top of your game by keeping your intellect sharp. While it may be easy to just sit in front of your TV, watching reruns of The Big Bang Theory, why not use that time to brush up on some chemistry, calculus, or general learning strategies?
Not that long ago I wrote an article discussing what it would be like, realistically, if you were to accidentally travel back in time to the Victorian era. At the end of that article, I mentioned that the best thing you could bring with you on a time-traveling adventure is a Kindle, or similar e-reader, stuffed full of the knowledge of the 21st century. Why a Kindle? Well, I own a Kindle, and I love it. However, there's far more to it than that.
Cooking isn't something that interests me much, unless it results in a fast burning fuel and a successful rocket launch!
For years, astronomers have been trying to figure out how our galaxy came to be. Even with the help of high-performance computers, no model of a spiral galaxy has ever been able to recreate the Milky Way, until now. An international team of researchers has created the first successful simulation of what happened 14 billion years ago to give our galaxy its unique shape. Turns out, all they needed was a bigger bang. Photo by IntelFreePress
Even the best-maintained kitchens occasionally get a fruit fly infestation. These critters descend, lay eggs (up to 500 at a time!), and then disappear usually only after extreme cleaning efforts (i.e., finally attacking that weird puddle of goo behind your refrigerator).
