I am using advanced lead-carbon batteries (these ones) in an off-grid solar system. The spec specifies equalizing voltage 14.1 V for 12 V block @ 25 °C (77 °F). I keep the batteries in an outdoor shed, and the temperature where I live tends to hang around 0 °C (32 °F) these days.
So, for lead ac...
We know different types of atoms have different spectral lines. But what exactly are the spectral lines representing? What causes white light to have a continuous spectra while other atoms show discontinuous spectral lines?

As I understand, polarity in molecules comes from the difference in electronegativity or the ability of the atoms to attract eletrons so the electrons spend more time or are more probable to gravitate more around the atom with stronger electronegativity right? So I wonder why polar molecules must...
I wanted to ask a question about NMR for Axial and Equatorial molecules.
I was asked to describe how to separate the following two product molecules from this reaction:
and the answer that my colleague mentioned was NMR.
He stated that for the product on the left, the $\ce{P}$ atoms were i...Transcript for
