hey does salt dissovle or react with ethanol ?

hhmmm, ok thanks, this lead me to another question. you can increase the boiling point of water by adding salt to it, is there any other compound that could be added to water to increase the boiling point of water higher than salt does? my idea is that if you can increase water's boiling...

Hi, i have more of a chemistry than a physics question. I am conducting an experiment to separate ethanol from water via fractional distillation, however through calculations i have found that some of the ethanol remains bonded to the water due to the strong hydrogen bonds. Is there any other...

Hi, i have a question, if we imaging that the universe is static and not expanding, what observation would be made in regards to red shifts in galaxy spectra?

how would i prove that mathematically ?

ok i thought i had it but i didnt, could u please prove that theory mathematically, i tried inputting the numbers but ended up with 610.24234...

i know that the forces have to be balanced to have orbit, u didnt understand my analogy. can someone please actually help me?

just point me in the right direction with some tips or momentum

do any of kepler's laws apply here?

this is my theory, its more conceptual that it is mathematical and i could be wrong. If you have a 1kg marble tied at the end of a string and spin it, it will have a certain amount of centrifugal force, however if you had a 10k marble on the end of a string and spun it at the same speed it...

Can someone help me with this question? A science group put a satellite of mass 'm' KG into a circular Earth orbit of radius 'r'. The orbital velocity it needs to remain in this orbit is v. They now put another satellite into a simmilar orbit at the same altitude. Its mass is 3 times 'm'...

thank you very much, your post made something click in my mind, i got it now. thanks

i don't know what to calculate
