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...

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.
In this trick, use vinegar and baking soda to isolate clear carbon dioxide gas, which you can then pour onto a candle to magically extinguish it.
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.
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, I will show you how to make copper glow red hot with the catalytic oxidation of acetone. For this science experiment, we'll just need some acetone, copper wire, and a flame source to initially heat the copper coil we'll make.
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.
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...
Sea otters are the largest members of the weasel family. When people started hunting sea otters for their fur, their population fell from roughly 225,000 to about 1,500, until the International Fur Seal Treaty took effect in 1911. Since the international ban on otter hunting, the population has rebounded back to roughly 107,000.

If you have some dry ice, try this cool science experiment out. It's so easy, you have to try it, at least once! You just need a chunk of dry ice and some metal coins, like a half dollar (which is comprised of copper and nickel).
When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.
Everyone starts their mornings differently, but one common thread amongst the masses tends to be the consumption of coffee, albeit in many different forms—instant, pre-ground, K-Cups, Nespresso, and so on. And I'm sure that we all have our own preferred methods, as well.
Sulfuric acid is mixed with sugar, which is attacked by the acid. The final products are carbon, water vapor, and sulfur dioxide gas.
A fire snake, also referred to as a black snake or sugar snake, is a classic science experiment you can do right in your own kitchen using a baking soda and sugar mixture and a fuel to ignite the reaction.
What is MnSO4 and MNO2, anyway? They are they molecular formula for Manganese Sulfate and Manganese Dioxide. And you can make one from the other. But how?
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...
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.

In this video, I'll be showing you how classic black snakes work and how to make them at home. There are actually two methods covered in the video — one that uses fire and one that does not. So just choose the one that fits best for your situation.
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.
In order to make manganese dioxide electrodes, you're going to need cobalt nitrate and manganese nitrate to do it. Making cobalt nitrate is fairly easy, but making the manganese nitrate is a little more complicated. But not impossible.
With all due respect to the fine folks at DrinkTanks, it's a little surprising that no one came up with their idea sooner. After all, last I checked, beer was pretty darned popular.
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.
