How many atoms are in 2.87 L of {eq}\rm H_2 {/eq} gas at STP?MoleIt is defined as the amount of substance that contains as many atoms or molecules or particles as there are grams of {eq}{}^{{\rm{12}}}{\rm{C}}{/e
noble gas atomsThis article studies the interaction the methane radical cation (C 2v ) with noble gas atoms (He, Ne, Ar, and Kr). A number of stationary points, between 5 and 7, have been located depending on the interacting noble gas atom. MP2, MP4 and CCSD-T computational levels ...
Gasoline is known as analiphatic hydrocarbon. In other words, gasoline is made up of molecules composed of nothing but hydrogen and carbon arranged in chains. Gasoline molecules have from seven to 11 carbons in each chain. Here are some common configurations: H H H H H H H | | ...
Some large atoms are very stable and quite happy to stay as they are pretty much forever. But other atoms exist in unstable forms called radioactive isotopes. They're the atomic equivalents of wobbly old buildings: sooner or later, they're bound to fall apart, splitting into bits like a ...
At the atomic level different rules of physics apply to those that we observe around us. These quantum rules determine how atoms interact with each other, and this new understanding will enable us to use quantum rules for incredibly advanced and rapid calculations that are far beyond the abi...
The number of atoms in a gas depends on the chemical formula for the gas itself. The number of atoms in the gas, and the types of atoms, greatly affect its density, with gases like tungsten hexafluoride having a density of about 11 times that of air....
This leads to the definition of an equivalent, or specifically a milliequivalent: (mEq = dfrac{(mass)(valence)}{MW}) This equation assumes that both mass and MW, or molecular weight (the same as molar mass but applied to molecules instead of single atoms), are given in milligrams. ...
One of the best places to measure possible dark matter interactions are galaxy clusters. A galaxy cluster contains vast amounts of dark matter, hot gas and assorted galaxies, all wrapped up in a gravitationally bound volume millions of light-years across. When two galaxy clusters collide, the ...
If you look atthe parts of the periodic table, you'll notice that all of the elements are arranged in columns called groups. Group 18, the furthest column to the right of the table, is typically colored differently than the rest, signifying a family of elements unlike any other. These ar...
