Every fire needs three things to burn: heat, oxygen, and fuel. As long as those three things are met, the fire will persist. If you are cooking with grease and a fire starts, you must react fast. Grab an oven mitt, find the lid that fits the pan, and smother the fire. Slide the cover over the pan to cut off the oxygen, and turn off the burner.
In this Education video tutorial you are going to learn how to draw the Lewis structure for carbon dioxide & methanol. Carbon dioxide is CO2. Oxygen atoms don’t bond together. So, carbon atom has to be in the center. Oxygen has 6 valence electrons and carbon has 4. Hence, carbon wants to form 4 bonds and each oxygen atom wants to form 2 bonds. So, two each electrons of carbon will bond with 2 electrons of each oxygen atom. The Lewis structure for CO2 will be ( …. O=C=O….). The 4 dots within t...

To calculate percentage composition we will take the example CO2 it stands for Carbon-Di-Oxide. It is the composition of Carbon and Oxygen. We have one carbon and its weight is 12.01 and 2 oxygen. So, we will multiply 2 with 16.00 which is the weight of the oxygen.
TTUchme1010 teaches viewers how to draw the lewis dot structure for sulfate. The formula for this is SO4^2-. 2- means we will have to add 2 electrons into the lewis dot structure. First, we will have Sulfur in the middle with Oxygen surrounding it. Sulfur is in group 6A so it have 6 valence electrons and oxygen has six, so fill this all in around the elements. Now, you have to add in the 2 extra electrons onto the most electronegative atom. This will be oxygen. Now, you should start bonding t...

In this video, we learn how to make your own charcoal. First, you want to make a stack of wood you have laying around, anything you have from scraps. Now, push the wood into a small empty pant can until you cannot fit anymore. Then, place the top onto the can so no oxygen gets into the can. After this, load the cans into a large barrel that has large air holes in it, then wait for the wood to turn into charcoal! This is a process that does take a long time and when finished, the can is going ...
This reaction is between metallic magnesium and carbon dioxide. Magnesium reacts with oxygen in the air to form magnesium oxide, but when the only source of oxygen is from CO2 the reaction becomes much more energetic. The products are white magnesium oxide and black carbon.

In this video tutorial, viewers learn how to drink Merlot. Begin by pouring the Merlot into the glass and gently spin it to allow the liquid to spin at the bottom of the glass. This will coat the sides of the glass with liquid and add some oxygen to the mix. Adding oxygen will allow you to get a better scent of the Merlot aroma. As you lift the glass up, look at the "leg" of the wine. Then smell the aroma of the wine. As you drink the Merlot, take small sips. This video will benefit those adu...
This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...
