What was bohr’s contribution to the planetary model

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.

Total the mass on the syringe. record it in the correct row of the data table. kg done click and drag weights to change the pressure. click the syringe to zoom in and see the volume. intro
