A gas that is lighter than air has a molecular weight less than the weighted average of the molecular weights of the gases in air, that is, 28.966. So, how does a molecule like Freon-12 CCl2F2, with a molecular weight of 120.9, get into the stratosphere?
To help you get started, we’ve compiled a list of 200+ chemistry research topics organized into different categories. Whether you're interested in organic chemistry, biochemistry, or nanotechnology, you'll find inspiration for your following paper or project. 1. Organic Chemistry research topics ...
Sodium Metabisulfite is a strong reducing agent. When contacting water, it will release sulfur dioxide gas, which is toxic and irritating to the respiratory system. Therefore, carefully handling Sodium Metabisulfite is very important. Wearing appropriate personal protection equipment(PPE), such as gloves...
Genesmay be an important factor triggering the development of alcoholism. Research has indicated that children of alcoholics are four times more likely to become alcoholics themselves; and while this statistic is at least partly due to environmental factors, scientists have determined that there is a...
Pregnant women using snus gave birth to babies weighing an average of 1.4 ounces less than non-tobacco users, were twice as likely to deliver prematurely, and are more likely to suffer pre-eclampsia than both smokers and nontobacco users [source: Gartner et al.]. Snus also creates greater ...
The rebate or step helps break up the flow of muzzle gas over the base and adds about 10-15% to the total accuracy (or decrease in dispersion, to be more precise) compared to a conventional boattail design.The advantages of the RBT over conventional BT bases are great enough that Corbin...
All the rest of the graphs in this section are pretty much flat. Overall they slope a teeny bit in a promising direction - blood pressure is the best of these, but blood pressure isn't what this study is supposed to be about; measure enough things and you're guaranteed to findsomething...
Using this law, we can calculate the rate of diffusion or effusion of molar masses of unknown gases using the molar mass of the given gas. The main application of this law is to separate the gases having different densities.A...
That cost is often passed on to the consumer in the product's price. If "brand name" is important to your image, then buying a brand name is important. However, it is possible to find high-quality sunglasses that don't have a brand-name price. Shops like REI often sells store-brand...
Temperature is a measure of the average kinetic energy of a set of molecules, like a beaker of water or a container of a gas. Adding heat raises this molecular kinetic energy, and hence the temperature, while reducing it lowers the temperature. ...
