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...
In this video from nmsuaces we get a lesson in how to dispose of leftover lawn chemicals. Many gardeners want to know what to do with leftover materials and how to get rid of it safely.

After you are finished rinse the container at least 3 rinses. The rinse water must then be sprayed out in the area w...
Learn how to balance the three different types of chemical equations in simple steps. First take an equation, write down its reactants and products and write down the names of all elements. Now write down how many of each element are present in the equation. Now check which element does not match, in this case the Oxygen doesn't match. Now multiply the element or compound starting at two but now hydrogen doesn't match. Try to match them by multiplying the coefficients but now sulfur doesn't m...
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.
he age-old “shtick” about a rake handle smacking you in the face when you step on the teeth isn't funny. It's happened to me more than once. One of the problems is improperly storing rakes, hoes, shovels and other long-handled tools. They can be hung up in a garage or garden shed, but usually end up right at the door, where they fall down, and again become a dangerous problem. The garden tool shed shown solves the problem of long-handled tool storage and at the same time provides a separate s...
