    Breaking water molecule

    Hi, While a mere 1.3 volts can break bonds in a water molecule, I have been reading that it takes 2000-3000 degrees celsius to break same bonds thermally. Such high temperatures intuitively appear to be very high energy compared to 1.3 volts. Why does it take such high temperatures? How exactly...

    A Molecule With a Similar Molar Mass as CCl4?

    I need to find a molecule that has a similar mass as CCl4 but it can't be another non-polar molecule. PCl3 was the closest I could get it but had a lower melting and boiling point. I need to prove that a polar molecule with a similar molar mass will have a higher melting and boiling point...

    Numbering hydrocarbon branches - QUICK HELP APPRECIATED!

    Hi! I've been given the alkene "3-ethyl-4-propylheptane". I found nothing wrong in the name, however, the 4-prefix (before propyl) is unnecessary since if the propyl would be sitting on ANY other carbon, the longest carbon chain would change and it would no longer be a heptane. My question is...
