Divide the mass of the compound in grams by the molar mass you just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or 1.39 moles.
(does this belong in chemistry?)
anyways, the parent was most likely a kid who wanted privacy. they wanted something so they are giving it to their kids.
no...the atoms will not behave the same
as when temperature is increased, the atoms vibration and kinetic energy will also be increased....they come in excited state...
where as when temperature is reduced ,atoms kinetic energy slows down....
The atomic radium increases to the left and downwards on the periodic table.
By that logic, Se has the largest radius.
Answer: Fire requires oxygen to burn. Water "smothers" fire and prevents it from acquiring more oxygen. Fire also requires heat, which cool water may prevent/remove.
