How To: Draw the Lewis structure for carbon dioxide & methanol

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...

How To: Experiment with carbon dioxide gas

Mr. G plays with chemicals and fire (what a surprise), for a really cool demonstration. An experiment you'll want to try, and probably can try immediately, as all materials (vinegar and baking soda) are likely in your house already. Exothermic reaction and gas displacement at its best!

How To: Use a carbon dioxide fire extinguisher

In this video tutorial, viewers learn how to use a fire extinguisher. The fire extinguisher contains carbon dioxide. Begin by pulling the pin on the top of the fire extinguisher. The will unlock the lever. Now lift up the nozzle and aim the fire extinguisher at the fire. Then squeeze the lever to release the extinguisher agent. As you are spraying the extinguisher, use a sweeping motion to move it back and forth until the fire is completely out. This video will benefit those viewers who do no...

How To: Make a CO2 powered bottle rocket

Sure, carbon and oxygen are two of very most fundamental building blocks of all life on Earth — but what have they done for you lately? With this free video guide, you'll learn how to build a safe, simple carbon-dioxide-powered bottle rocket with baking soda and a spent soft plastic waterball.

How To: Make manganese dioxide electrodes

Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.

How To: Calculate your carbon footprint

Watch this video tutorial to learn how to calculate your carbon footprint. A carbon footprint is an equation that estimates just how much you, personally, are contributing to global warming—and all you have to do is plug some info into an online calculator. Figuring out how to make your footprint smaller, of course, is another matter.

How To: Proof yeast

Learn how to proof yeast. Yeast is used in baking as a leavening agent, which is what makes bread and pastries light and airy. Yeast reacts with moisture, sugar, and heat to create tiny bubbles of carbon dioxide which cause the dough to expand and rise. To proof yeast, you'll need yeast, sugar, moisture and warm environment.

How To: Understand organic molecules & elimination reaction

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...

How To: Make seltzer water

Sick of spending your hard earned money on the bourgeois bubbly water? Why spend extra money on bottled seltzer when you can make it at home? Plus, by using fewer plastic bottles, you can reduce your carbon footprint.

How To: Put out a candle with an empty glass

Amaze and amuse your friends with this fun magic trick! Using only vinegar and baking soda, which you may remember from some of the bottle-bomb-making videos elsewhere on the site, you can create carbon dioxide which, since it's heavier than air, can be used to invisibly fill a glass and then be poured onto a candle, extinguishing it without looking like it's done anything at all! No word on how long the gas will stay in the glass, so set this one up right before you want to do it and then hi...

News: Scientists Turn Bacteria into Mini Cyborg Solar Panels

Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.

How To: How to Make a Dry Ice Crystal Ball - DadLabs.com

In this video, we learn how to mow to Make a Dry Ice Crystal Ball! This is a fun activity you can do with your kids and that you will enjoy as well. To start, you will need to take some Dawn dish soap that doesn't have soap and isn't anti-bacterial. After this, put this in water and add rags into it. Swish it around to make the water bubble up. Now, grab a smaller bowl and fill it with water. Then, take another bowl and put dry ice in it using a glove. Next, Now, drag the rag over the top of ...

How To: Understand the hemoglobin & its role in the body

An in-depth explanation of the structure of the hemoglobin molecule, the process by which it binds with the oxygen in the lungs, how it dumps the same oxygen molecule at the appropriate location in the body and how carbon-dioxide gets attached to the hemoglobin molecule are the topics which the narrator in this video explains with diagrams and a few equations.

How To: Synthesize copper(II) carbonate & sodium bicarbonate

This actions is a video tutorial in the Education category where you are going to learn how to synthesize copper(II) carbonate & sodium bicarbonate. For this you will need copper sulphate which is available in root kill and sodium bicarb which is baking soda. Take 100g of copper sulphate and dissolve in about 400ml of water. Now take 69.27g of baking soda. Add baking soda very slowly and keep stirring the solution. You got to be very careful as the chemical reaction will produce lot of carbon...

How To: Kill bed bugs with glue boards & monitors

The CVC 3000 is a monitor. It is an active bed bug monitor that use attractants to lure bed bugs to it. It is another tool in bed bug management. It contains a carbon dioxide cylinder/cartridge. The capture slides will be trapped on a tray. The capture slides are one time use capture slides. They have to be replaced each time. The cartridge lasts 10 hours, and it has to be replaced every 10 hours. To use, you will need to place it near the area, where you suspect infestation. Just lie it flat...

How To: Fix strecthed or wrinkled earlobes

In this video Dr. Schultz will show you how to fix stretched or wrinkled earlobes. Here are a few things you can do to remedy stretched or wrinkled earlobes: Laser treatments, especially carbon dioxide treatments, a specified amount of heat is delivered to the skin, and it causes a contraction, which causes a plumping of the earlobe, removing the wrinkles. The results will last for years. With injectable filler treatments like collagen, you will also find a plumping of the skin, but they will...

How To: Make a dye-sensitized solar cell with titanium dioxide and anthocyanin

Discover the power of raspberries! Literally. In this NurdRage science video, learn how some crushed raspberries and some titanium dioxide (TiO2) can create a powered dye-sensitized solar cell. Inside a raspberry is something called anthocyanin, which is a flavonoid pigment. Commercially purchased solar cells are way more powerful than this DIY solar cell, but with a little improvement, who knows. Nurd Rage also lets you know how this works.

How To: Make a bottle of beer appear to instantly freeze

This video shows you how to make bottle of beer appear to instantly freeze. It's hard to believe, but the process is very simple. Take a beer bottle and keep it in refrigerator, do not freeze it. Allow it to cool for some hours. After that take it out and check that it is still in liquid state, then tap it strongly on the bottom side and wait for few minutes. You can see that it has been completely frozen. This is due to the process of carbon dioxide present in the beer bottle.
