Document Summary
All matter is composed of particles atoms, ions, molecules. If you change the molecular structure of an atom, you will lead into different properties of the matter and change the behavior of the matter. Stronger interactions = less space, less mobility, more rigidity, more condensed state. As you change the state, the interactions get weaker (solid liquid gas) Mixture homogeneous mixture vs heterogeneous mixture. Fixed and definite water compound. If you can"t separate it, its element (physical method) In a chemical reaction, matter is neither created nor destroyed. Adding the masses of two different elements to get the total mass. If mass is conserved during a reaction, whatever is making up the matter must still be present somehow. The law of definite proportions (law of constant composition) Samples of a given compound(s), regardless of source or method of preparation, have the same proportions of their constituent elements.
