PH3 - three single bonds, all P-H. One unshared pair on the P BF3 - three single bonds, all B-F. Note: only 6 electrons in valence shell of B. Each F has three unshared pairs. SO3^2- The S is central to the three oxygens. One oxygen has a d…

false CO2 is linear, NO2 is angular

Change mg/mL to mg/L: mg/mL times 1000 mL / 1 L = mg/L

That's a rather broad question. I have a number of empirical formula tutorials and solved sample problems here: http://www.chemteam.info/Mole/Mole.html I also took the text of your question and did a search: https://www.google.com/search?q=…

2.58*10^24 molecules divided by 6.022 x 10^23 molecules / mole = the answer you seek

Your friend is correct. The ratio 1 to 2.537 is closer to 2 to 5 and it is to 1 to 3. P2O5 is the empirical formula. P4O10 is a molecular formula and could not be calculated using the data your provide in your question. Only the empirical form…

Strong and weak refer to the degree of dissociation and not to their ability to neutralize or not neutralize. Strong acids and weak bases (or weak acids and strong bases) will neutralize each other. You are quite welcome. Here is my web site: …

That's a very good score. Congratulations. I think this merits a bit of a celebration. Ice cream with some friends seems appropriate.
