When water vaporizes into the air, it becomes humid out.

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

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.

In general metals get as you move from left to right across the periodic table.
