How To: Swim a proper freestyle

New techniques may improve a swimming pool workout from Masters coach Nancy Kirkpatrick Reno. Before sticking a toe in the water, consider this advice: * Swim in a pool that's at least 20 to 25 yards long; those pools can usually be found at high schools and some gyms. A 50-meter Olympic-size pool is best, but not everyone has access to that. "If you're going to become a lap swimmer," Kirkpatrick-Reno says, "you can't go any shorter or you'll be constantly turning." An outdoor pool is prefera...

How To: Balance a chemical equation easily

In this video, we learn how to balance a chemical equation. First, take a look at both sides of the equation and figure out how many atoms there are for both. Once you write this out, you will have an idea of how unbalanced it is. Now that you've done this, you need to think about how you can make the equation equal. Look at the first line and then see how many you have to add to one side to make both equal to each other. Then, go to the second line and do the same. When finished, you will ha...

How To: Easily balance a chemical equation

In this video, we learn how to easily balance a chemical equation. In a balanced equation, there should be the same number of atoms on both sides of it. There are no rules that explain how you get a balanced reaction from expression. First, start on the molecule or compound that is the most atomically complex. After you look at this, you can learn how to make the rest of the equation equal to each side. This is a complex process that you must walk through to figure out, but it will result in ...

How To: Identify willow tree damage caused by a borer

Weeping willows, globe willows, corkscrew willow, cotton wood are all prone to bores than other diseases. They grow in fertile soil with lots of moisture. Never treat tree chemical. Prune as necessary, take out dead diseased limbs, water and fertilize regular. This ensures the tree lasts longer and that the tree is less attractive to insects. Where tomatoes are concerned to avoid sunburn ensure that they are slightly covered with the folding of the plant. High salt level of water or chemicals...

How To: Balance chemical equations with MyTutorBuddy

Learn how to balance chemical equations with MyTutorBuddy. Learn about this in this video tutorial. There are four easy steps to do this. Step #1 – place 1 by the most complex compound. Step #2 – balance anything that is not an element. Step #3 – balance the elements. Step #4 – multiply by the lowest common multiple. The 4th step doesn’t always come in to play. The video demonstrates with an equation: C3H8 + O2 -> H2O + CO2. But, this equation is not balanced. Using the 1st three steps, the v...

How To: Kill Cockroaches in a Green Way

Cockroaches are one of the most durable and and irritating forms of life on Earth. Many turn to toxic chemicals to get rid of them, but that's not very green is it? This video will give you some eco-friendly tips for preventing infestations, trapping insects, and disposing of them once you've caught them. Yes, cockroaches are part of nature. No, that doesn't mean we're not going to kill them.

How To: Follow three rules to balance chemical equations

In this video, we learn how to follow three rules to balance chemical equations. The first rule is that you need to start by balancing elements that appear in only one reactant and one product. The second rule is that you need to multiply through by common factors. You must retain equal numbers of atoms of each element on both sides of the equation. The third rule is: if an atom appear in elemental form on one side of the equation, save it for last. Going over the rules of how the balance the...

How To: Understand chemistry & chemical change

This video tutorial is in the Education category which will show you how to understand chemistry and chemical change. The question here is 10g of Mg ribbon reacts with 0.15 mol decimeter cubed of hydrochloric acid at 25 degree Celsius. What is the balanced equation for this reaction? When magnesium reacts with hydrochloric acid, you will get magnesium chloride and hydrogen. So, the equation will be Mg + 2HCl = MgCl2 + H2. Mg is in group 2 of periodic table and has a valance of 2, whereas Cl i...
