These changes in matter do not result in a substance with a new _______. In other words the ________ of the substance remains the same before and after the change Examples: MELT BOIL FREEZE CONDENSE SUBLIME DEPOSIT EVAPORATE CUT MIX FILTER GRIND DISSOLVE STIR DECANT CENTRIFUGE These changes do not involve bond ________ and bond __________.
These changes in matter result in a substance with a new _________. In other words the _________ of the substance is altered due to the change. Examples: REACT ROT SPOIL DECAY RUST OXIDIZE REDUCE CORRODE BURN EXPLODE COOK CHARGE RECHARGE DECOMPOSE DIGEST RESPIRATION COMBUSTION PHOTOSYNTHESIS FERMENT These changes do involve bond _________ and bond _________.
These properties of matter are observable without any accompanying _________ in identity. You need not ________ the identity of the substance to observe these properties. Examples: COLOR MASS VOLUME LENGTH MAGNETISM TEMPERATURE HARDNESS LUSTER MALLEABILITY CONDUCTIVITY AREA WEIGHT TEXTURE DENSITY MELTING PT BOILING PT DIAMETER RADIUS HEIGHT SOLUBILITY ___________ vs. ___________ Physical Properties
These properties of matter are observable only with an accompanying ________ in identity of the substance. You must ________ the identity of the substance to observe these properties. Examples: CORROSIVE FLAMMABLE REACTIVE EXPLOSIVE TOXIC OXIDIZER REDUCER POISONOUS CAUSTIC COMBUSTIBLE Because these properties require a change in identity, they are usually just _________ forms of the chemical changes already mentioned.
1) There is no change in molecular/atomic identity. 2) These changes are generally easily reversible.
1) Formation of a ___________. 2) Appearance of a new ___________. 3) Energy _______________. 4) Energy _______________. 5) After mixing together two _______________, a ________ _______________ forms. Generally speaking chemical changes are not easily ____________________.
