Okay, thanks a ton. I can take it from there!

Hi all, The question is: Given that X follows a geometric distribution, prove that P(X>j+k | X>k) = P(X>j). So this is all I have: P(X>k+j) = (1-p)^k+j, (a proof covered in the text)...

Sorry, I had deltaH in moles. So I see what you're saying; all the heat that goes to warming the ice to 0ºC comes from the water, which in turn freezes portions of it. So step one, calculate the energy it takes to raise 2kg of ice to 0ºC, then negate that answer and set it equal to the bond...

Homework Statement A 2kg block of ice initially at T = −20 ◦C is put in contact with a very large amount of liquid water at T = 0 ◦C (by “very large amount” we imply that by the time ice and water reach thermal equilibrium, there will still be some liquid water left). Ice and water can exchange...
