  1. Properties of Matter Chemical Properties Ch. 1 Sec. 3 (p. 16-21)

  2. Chemical Properties (p. 16) Chemical properties of matter describe matter’s ability to __________ into new matter that has ____________ properties. 2 examples of chemical properties: 1.)flammability- the ability of substance to ______ 2.)reactivity- the ability of two or more substances to ____________ and form one or more ______ _______________. CHANGE DIFFERENT BURN COMBINE NEW SUBSTANCES

  3. Comparing Physical & Chemical Properties (p.17) Physical properties can be easily __________ without changing the substance’s identity. (EX: density, hardness) Chemical properties aren’t easily __________. A substance always has its ___________ ___________________, even when you can’t see them happening. (EX: wood is flammable, iron is reactive with O2) OBSERVED OBSERVED CHEMICAL PROPERTIES

  4. Characteristic Properties (p. 17) THE Characteristic properties are always ____ _______, no matter what size the sample is. They can be _____________ ___________ (EX: density or solubility), or ____________ ________________ (EX: flammability or reactivity). Scientist use these characteristics to __________ & ____________ substances. SAME PHYSICAL PROPERTIES CHEMICAL PROPERTIES IDENTIFY CLASSIFY

  5. Chemical Changes (p.18-19) DO Chemical changes ___ form new substances! Q: How do you know when chemical change has occurred? A: The properties of the new substance(s) will be ____________ than those of the original substance(s). Chemical changes change the _________ of the matter involved. Most can’t be ______________! (EX: baking a cake) Some can be reversed by using more _________ ___________. (EX: splitting H2O molecules) DIFFERENT IDENTITY REVERSED CHEMICAL CHANGES

  6. Telling the Difference Between Physical & Chemical Change (p.20-21) The most important question to ask to determine whether a change is physical or chemical is… Did the _____________ change? Composition is what type of ___________ makes up an object & how that matter is ____________. If the answer is ‘Yes, the composition has changed’, then a ________ _________ has happened! (EX: electrolysis- splitting liquid H2O into hydrogen and oxygen gases) If he answer is ‘No, the composition is the same’, then a _________ _________ has happened. (EX: ice cube melting- it can be refrozen) COMPOSITION MATTER ARRANGED CHEMICAL CHANGE PHYSICAL CHANGE

  7. Examples of Chemical Properties: Flammability/ nonflammability Reactivity/nonreactivity pH Examples of Chemical Change: Burning Rusting Photosynthesis Digestion Explosion Cooking/Baking Making Odors Effervescing/bubbling
