Atomic Mass Atoms are so small, it is difficult to discuss how much they weigh in grams. Use atomic mass units. an atomic mass unit (amu) isCH O® CO HO
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a
First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: \(\mathrm{2g\enspace NaCl\Biggl(\dfrac{1mol\enspace NaCl}{58.44g\enspace NaCl}\Biggr)\Biggl(\dfrac{6.022\times10^{23}\enspace molecules\enspace NaCl}{1mol}\Big...
If all goes well, mushrooms begin to grow after a week or two and are ready to pick when the caps begin to turn upward. Each cake can produce mushrooms for up to a month, usually in waves, called flushes. A single cake can produce dozens of mushrooms. They can rot pretty quickly, ...
Small particles in the disk stick together and make bigger pieces, like building blocks, which turn into baby planets. When the baby star gets really hot, it starts to shine by turning hydrogen into helium, and that's when it becomes the sun. The baby planets orbit, they collect more pie...

where C is carbon, H is hydrogen, O is oxygen, the hyphen is a single chemical bond between the atoms and the || symbol is a double bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. When ethanol is oxidized to acetic...
Rutherford concluded that thegold atoms were mostly empty space, which allowed most of the alpha particles through. However, somesmall region of the atom must have been denseenough to deflect or scatter the alpha particle. He called this dense regionthe nucleus(seeThe Rutherford Experimentfor an ...
If you would like to solidify it and turn it into margarine, what you do is hydrogenate it. That is, you saturate it with hydrogen by breaking the carbon double bonds and attaching hydrogen. To do this, you heat the oil and add pressurized hydrogen gas and a nickel catalyst. In this ...
