At stp, which sample contains the same number of molecules as 11.2 liters of co2(g) at stp?
(1) 5.6 l of no2(g) (3) 11.2 l of n2(g)
(2) 7.5 l of h2(g) (4) 22.4 l of co(g)

Ineed ! it’s science and it’s due tomorrow!

Name the intersection of plane bpq and plane cpq.

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
