1 - States of Matter Flashcards
Where will the neutral product form ? And why
NH3 HCl
Mr17 Mr 36.5
about 2/3 from NH3 to HCC
Because the less mass, faster the movement

What are the features of ice ?
- low melting point due to weak intermolecular forces
- very strong. Will not break easily due to regular arrangement of molecules and each molecule makes 4 intermolecular forces
What are the special features of water, as a liquid vs solids
liquid is more dense than solid, for no specific known reason
What are the 2 main ideas in the kinetic theory of matter ?
- All matter consists of very small particles which are constantly moving, or in a continued state of motion
- The degree to which the particles move is determined by the amount of energy they have and their attraction to other particles
What are all the state changes involving solids, liquids and gases?
see card
- solid to gas - sublimation
- solid to liquid - melting
- liquid to gas - boiling/evaporation
- liquid to solid - solidifying/freezing
- gas to liquid - condensation
- gas to solid - deposition
