A plane drops a hamper of medical supplies from a height of 2960m during a practice run over the ocean. The planes horizontal velocity was 108m/s at the instant the hamper was dropped. What is the magnitude of the overall velocity at the hamper at the instant it strikes the su...

The pH of a solution prepared by mixing 50.0 mL of 0.125 M KOH and 50.0 mL of 0.125 M HCl is __________. i know the answer is 7.00, but im not sure how to solve it, do i create an ice chart?

ok thats where i got the number 8260000kj=kj uuuggggh i dont know what im doing wrong!!

ok thats where i got the number 8260000kj=kj uuuggggh i dont know what im doing wrong!!
chem 1406
ok so (2000moles/1)(4130kj/1mole) = (kj/2000 moles)(2000 moles/1) (2000)(4130kj) = kj now what?
chem 1406
ok so then i set it up wrong it should be 4130 kj/1 mole = 2000 moles/kj and that time i got 8260000 i dont know if that is right because the kj would cancel out too
chem 1406
i got 2.065 kJ/mole
chem 1406
so i would set the problem up like this.... 4130kJ/1 mole = xkJ/2000 moles ???
