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.
Breathing oxygen is an extremely important component of staying alive, right? Well, the same goes for running. If you're not breathing properly, you're running is going to suffer.

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...
Ideally, wine would stay as perfect and delicious as the day it was first uncorked forever. But, thanks to a pesky process called oxidation, re-corked wine (no matter how you do it) pales in comparison to a fresh's bottles original magic.
In this tutorial, we learn how to begin composting. When you compost, you have a lot of choices of where you want to compost. You can do it inside of a metal bin, in a small tumble type of container, or a wood cedar box. If you are doing a lot of composting, use a large composting bin that you will turn with a shovel. It's important to get oxygen into the pile to keep the bacteria growing. You can use compost accelerator to help get things going and make it more successful. You can compost co...

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 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...

This is a video tutorial in the Education category where you are going to learn how to use and understand chemical equilibrium in Chemistry. This video answers a question about the contact process. This is a process by which sulphuric acid is made where they take sulphur, react it with oxygen to make sulphur dioxide and react it with more oxygen to make sulphur trioxide. The equation here is 2SO2 + O2 will give us 2SO3. This reaction is exothermic, that means it will give out energy in the fo...
To use yoga exercises to wake up and stay awake at work, begin by doing breathing stretches: i.e. cow to cat stretches. Inhale, expanding your chest out for the cow stretch, and exhale concaving your chest into the cat stretch. Next, do side stretches from left to right. Repeat these. Next, add 4 punches: left jab, right jab, undercut, and undercut. Extend your arms fully. Repeat all of the steps together.
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...
