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...

This is a video tutorial in the Education category where you are going to learn how to balance a chemical equation step-by-step. The left side of the equation is called the reactants and the right side is the new products. What will be new products when silver nitrate reacts with ferric chloride? The left side will be written as Ag NO3 + Fe Cl. The valence of Ag is +1, NO3 is -1, Fe is +3 and Cl is -1. On the right side the silver cannot go with iron because both are positive. So, it will be ...

This is a video tutorial in the Education category where you are going to learn how to understand polyatomic chemical formulas. When writing the formula using polyatomics, the same cross-over rule applies. 1st identify the metal and non-metal. Then you write the symbols, write the charges, cross-over the charges from top to bottom, remove the charge and simplify the numbers and remove the 1s. for example, iron (II) phospahate. The "ate" ending implies that phosphate is polyatomic. The symbol ...
We all want to spic and span our kitchen countertops, our tile floors, and our bathrooms. But for the most part we can bet you've been unwittingly using storebought detergent cleaners or bleach. While these cleaners are in fact excellent at removing grime and buffing your dirty floors to a Midas touch perfection, they also come filled to the brim with known cancer-causing agents, synthetic chemicals, and other gnarly, hard to pronounce crap.

We've worked hard to reduce the flow of toxic chemicals into our waterways, which means no more DDT and other bad actors to pollute or destroy wildlife and our health. But one observation has been plaguing scientists for decades: Why are large quantities of one toxic chemical still found in the world's oceans?
An atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged ions. The nucleus itself is a mixture of positively charged protons amd electrically neutral neutrons. Different groups of elements have respective atomic numbers. You can use the periodic table as a tool to draw atoms of elements. The periodic table is organized into periods, groups and families. This video is a tutorial that reviews the subatomic particles found in an atom. I...

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...

You'd think that in the United States we have more of a problem of women wanting to look tan year round than white and pale. But many women actually crave the vampirish pale complexion, and because not all of them are born with it, some turn to whitening/lightening creams. Some women also turn to these creams because they claim to fade dark spots.
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...
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 ...
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.
