Water is made of polar molecules and will not mix with very well with any non-polar...

Molar enthalpy is the amount of heat needed (cooling) or given off (exothermic) during a chemical reaction.

The question is... per mole if what? If it is obvious as to what substance in the...

The rotation of the moon and the revolving of the moon are in synk so we only see one side of the moon. But why that side of the moon? Why is the side that has most all the lunar seas (flat lands,...

So you are saying that "an object in motion tends to stay in motion?" I guess there is not very much friction out in space that would cause the Earth to slow down.

The answer to the questions of...

I decided not to use a pan. I bought shower liner and will use that along with...

Thanks doug,

Since the drain is already in concrete, I will have to go with that one. In a self-help book, I read that using a rubber membrane as the pan would be okay as long as the membrane is...

I am going to build a show base, 3' by 5' on a basement floor. The drain has already been placed in the middle of the 3by5 area.

On two of the sides there will be 4" cement footers poured to be...

doug238,
Thanks for you answer but what do you mean by "lead a 4" cast iron flange on the 4" cast iron pipe???

I like your idea of using hydrolic cement around the pipe. Do you mean that I...
