Whats the molecular geometry of HCN?

Linear Hcn Molecular Geometry Hcn Shape This Site Might Help You. RE: Whats the molecular geometry of HCN? I think its bent but not sure octahedral (Definitely not) tetrahedral trigonal planar linear bent they are right! >>Linear<< Lewis diagram: . . H–C≡N: It is linear with an sp-hybridized carbon You use a triple bond in …

Converting g/cm3 to lb/ft3?

So I have surfed and surfed the net and read and read through my chem and physics books and there is no clear conversion factor for g/cm3 > lb/ft3. Everytime I try to do the conversion I get different numbers. Its driving me CRAZY!!!! If someone could clearly write out the conversion factor for me …

For liquids, which of the following factors affect vapor pressure?

Vapor pressure is essentially only affected by the particular liquid and its temperature. However this is only an approximation. So from possibilities provided I would choose. Temperature Intermolecular forces temperature and intermolecular forces! Vapor pressure describes the pressure of the vapor phase in equilibrium with the liquid phase of a substance. Intermolecular forces and temperature …

In a redox reaction, electrons are transferred?

remember this…"reduction means reduction in charge" and this follows naturally… reduction means reduction in charge by gaining electrons oxidation means increase in charge by losing electrons. species reduced is oxidizing agent species oxidized is reducing agent. why is reduction the gain of electrons? because electrons are negative. the more negative electrons you add, the lower …

Average atomic mass of silicon?

Hello, I was wondering how do you find out these answers and what are the answers? 25. A: Given the following data, calculate the average atomic mass of silicon. isotope = Si-28 amu =27.9769 abundance(%) =92.18 isotope = Si-29 amu =28.9765 abundance(%) =4.71 isotope =Si-30 amu =29.9738 abundance(%) =3.12 Thank you! : ) Multiply each …
