Chemistry

I know this might be a silly question but I am confused with different answers of internet. My question is: Molar conductivity is given as: Molar conductivity = $\frac{\kappa}{M}$. S.I. unit of : $\kappa$ is $\pu{Sm}^{-1}$ & $M$ is in $\mathrm{mol \, m^{-3}}$. Thus, Molar conductivity in S.I. is $\mathrm{S ....

I'm trying to help lead my daughter to a solution and my high school chemistry is almost 30 years ago. For the following reaction, indicate the species being oxidezed and reduced and show the oxidation numbers above these symbols. Lastly, indicate the number of electrons that have been lost or .... Mason: 7 hours ago Chemistry ### Data repository of organic compounds Does there exist any data repository of chemical compound that gives the structure of the compounds with the help of coordinate geometry. It would be like each atom has a coordinate and the list of bonds it has with other atoms so that the 3D structure of the compound can ....
