Carbon is 12 grams per mole
Because if you start at one for example you starting at a extra cm/m/mm. So when you get your measurement result it will be wrong by just one cm/m/mm. Hope this wasn't too confusing.
Answer:
Good for you! : )
Explanation:
I don't know what happened but I am glad you are happy.
Both compounds are composed of covalent bonds and gaseous under room temperature and pressure. According to data, PH3 has a low boiling point than NH3, though the former being heavier than the later. This is due to intermolecular H- bonding in the later which is absent in the former. The oxidation state of phosphorous in PH3 is (- 3) as that for nitrogen in NH3. Both phosphine and ammonia react with oxygen to produce P2O5 gas and water, and N2 gas and water.
