How can we run a car on vegetable oil? Since the hydrocarbon chains for diesel fuel and for vegetable oil are simmilar a diesel engine should run on clean veggie oil.
We drew 2-d models of molecules and built 3-d models of hydrocarbons and compared them. Once we built the models and drew the diagrams it was easy to see how veggie oil could

In August, I wrote about a report by a prohibitionist University of Minnesota group claiming that one pinch of smokeless tobacco is five times more dangerous than smoking. They reported that smokeless tobacco products contain PAHs, a complex family of chemicals that are formed during the incomplete burning of almost any product, including c ...

D.C., Vermont and Boston you can see flavors like Cherry Garcia, Chunky Monkey, Phish Food and Half Baked in a new hydrocarbon freezer!
These freezers don’t release any Hydrofluorocarbons (HFCs), which are harmful gases that contribute to global warming.
What do I have to say about this?
“You scream, I scream, we all scream for hydrocarbon frozen ice cream!”

:
Ethoxylation is the process of chemically reacting ethylene oxide with fatty acids (or other hydrocarbons) to make them more water soluble. In cosmetics, hydrocarbons are good for making hair and skin feel smooth, soft and in better condition. But hydrocarbons don’t mix with water (think of separated salad dressing). So, chemists ethoxylate the compounds
