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...

In this how to video, you will learn about Chemiluminescence and the oxidation of Luminol. The first solution is Luminol and NaOH. The second is K3 and H202. Luminol is used to detect blood in crime scenes. It reacts with Iron in Hemoglobin. As you can see in the example, it illuminates the chemicals in the dark. This is why it is very useful for crime scenes. It can be used even if the blood is not visible with day light. Thus, it is an invaluable chemical in the name of science and justice....
Don't call a pricey plumber! Anyone with a few tools can unclog a drain -- without even resorting to those strong, toxic chemicals. Most of the time, anyway. You will need baking soda, vinegar, rubber gloves, cleaning rags or duct tape, a rubber plunger, a plumber's snake, petroleum jelly, a bucket or pan, and a length of hose. WARNING: Do not try this if you have already used a commercial drain opener, as it can create harmful fumes.

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. You should not store it. Once mixed up, use it all. Make your mix so you don't have to have a surplus that day. If you have a surplus, you need to spray it in an area that is labeled to be used. 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.
