How would one calculate change in enthalpy only knowing heat capacities of all substances involved/required? at a known T... WOuld you use a multi-stepped pathway and if so, how?

WHen talking about phase transitions, in a graph of Temperature vs. Heat Capacity, does the PT occur at when the graph has a gradient of 0 or somewhere else?

What does the phrase "like a pig going for truffles" represent? Persistence?

The international standard Kilogram in Paris is stored under double bell jars. What is the prupose of the jars? Is it because the jars create a vacuum to prevent the standard from gaining mass due to oxidation? If so, why double jars? Are there any other...

why is it not smart to replace coefficients in a blanced equation with the mass of each substance?

Letting L1=ax+by+c=0 and L2=px+qy+r=0. The equation of anyline passing through the intersection of L1 and L2 is L1+kL2=0 where k is a variable depending on just how the actual line through the point is. Can anyone prove this because all i get is 0=0.

Découvir en donnant Et donner en découvrant Tu trouveras ta place au coeur des tiens Discover while giving, give while discovering, you will find you place in your(singular???) hearts. And another question. How would one say "I like that a lot" or "I reme...

How can one count carbon atoms, eg. in the international mass standard stored in PAris. By mass spectroscopy?

maybe its the fact that its a TWO hour drive..... thatd stress me out if I had to do it daily

but how does (a + kp)x + (b + kq)y +c + kr = 0 relate to y-y' = m (x - x')?
