RE: Moles and volumes of gases Help..? - Yahoo! Answers

1. no. of mole = mass/relative molecular mass 2. no. of mole = volume/24dm^3 (room temp) first you need to know its no, of mole. use the 1st formula, e,g: ii) 320 / 2(16) = 10 mole then use the 2nd formula to get the volume (room temp) e.g: ii) 10 * 24dm^3= 240 dm^3 i hope you understand.

RE: What does current theories say about planets?

Started 2 weeks, 2 days ago (2008-09-25 17:26:00) by Jeff Root

Stars and planets form together, when a giant molecular cloud collapses either because it cools off and condenses or because it is compressed by nearby supernovae, or both. When the density of particles becomes great enough, collisions become more frequent. Even if the particles do not stick together, at least one of the particles will likely have a reduced speed relative to the ...

Ionic: Includes every ion in both the reactants and products (ie H+Cl- + Na+(OH)- ---> H2(2+)O(2-) + Na+Cl-) Net Ionic: Doesn't include spectator ions (those that take no place in the reaction). In the above example it would become H+ + Cl - --> H2O These should be simplified ------------------------ Ideal Gas Law: pV = nRT where p = pressure (Pa), V = volume (m^3), n = m/Mr (...
