Is it true that protons, neutrons and electrons differ from each other based on their locations in an atom but they have the same electrical changes

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

8. what happens to matter during a chemical reaction

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.
