When compounds are larger, does that mean they have higher melting points? Or is it inversely related?

Also, what about if its an ionic compound? How does size make a difference in the melting point?

Is there a better alternative to lye (sodium hydroxide) when making soap?

I'm making soap and I don't want to use lye since it's very hazardous.

Got any better suggestions that will work as well or better than lye for making soap?

Thank you!

I remember my teacher saying the flaw with Rutherford's model was that it doesn't explain why atoms do not fall towards the center of an atom. Why don't they fall towards the center? I guess this may fall into "Why doesn't the earth fall towards the sun". This may be a common sense questions, but no one has ever given me a straight answer about it before...

Alright, long story short, I'm about to start a really stupid project (don't you love it when it starts out like this?) I am curious as to what the effects of increasing the power to electrlysis, most experiments I've seen are about 12 volts and 12 amps and I was thinking more in the range of like 12 volts at........1,680 amps. Would the water instantly begin to boil? Also, for my electrolyte I've been using sodium bicarbonate (no chlorine gas to worry about.) My thought was if I used much more that could be suspended and just had "fans" in the water keeping it suspended, it would let more electrons pass through the water. I guess there are a few questions in here and any help surely would prevent me from blowing myself up. Thanks in advance.

why do you heat organic liquids under reflux for such a long time? why not just for a few minutes instead of 1/2 hour or even 45 mins?

properties. Draw dot & cross diagrams to illustrate the bonding in these compounds, and hence explain the difference in their melting points.

You dont have to draw the d&t diagram. Thanks.
