Vocabulary
| Question | Answer |
|---|---|
| What are the two different types of matter? | Pure Substances and Mixtures |
| What are the two types of pure substances? | Elements and Compounds |
| What are the different types of mixtures? | Homogeneous and Heterogeneous |
| classify : Iron | Pure substance element |
| classify : Wet sand | Heterogeneous Mixture |
| classify Carbon Monoxide | Pure Substance Compound |
| Classify : Orange Juice | Homogeneous Mixture |
| classify : Tea With Sugar | Homogeneous Mixture |
| classify : Air | Homogeneous Mixture |
| classify : Blood | Heterogeneous Mixture |
| what is Pure Substances | Composed of only one type of atom or molecule ( composed of one certain thing ) |
| What is Mixtures | Composed of two or more different types of atom and molecule |
| Type of mixture | Heterogeneous : not uniform , different layer Homogeneous : uniform same layer |
| Type of pure substance pure substance | Element : can't break it down anymore compound : composed or two or more element ( composed of one metal and one none metal ) |
| Mixture Separation Techniques Filtration: | Separation based on particle size |
| Mixture Separation Techniques Distillation : | Separation based on boiling point |
| Mixture Separation Techniques Chromatography: | Separation based on attraction to a stationary substance |
| Mixture Separation Techniques Crystallization: | Separation by removing liquid |
| What To Know | Pure substances cannot be broken down through physical means Mixtures can be separated |
| What is Chemistry | Chemistry is the science of matter and the changes it can undergo. |
| What is Matter? | 1.Matter is the material of the universe 2. Matter is anything that has both mass and volume .Mass is the amount of matter in an object .Volume is the amount of space and object occupies |
| The Nature of Matter | Chemists are interested in the nature of matter and how this is related to its atoms and molecules. |
| States of Matter | Solids Liquids Gases Plasma |
| The Kinetic Nature of Matter | Matter consists of atoms and molecules in constant random motion |
| Solids | have a rigid shape and fixed volume. Their external shape can reflect the atomic and molecular arrangement. |
| Liquids | have no fixed shape and may not fill a container completely. |
| Gases | expand to fill their container. |
| Plasma | an electrically charged gas The Sun or other stars Most abundant state of matter in the universe |
| Particulate Nature of Matter | 1. All matter is made of atoms 2. Elements are made up of atoms of the same type 3. Compounds are formed when atoms chemically bond to one another in a specific way |
| Properties of Matter | Physical vs Chemical Properties |
| Physical properties | Can be observed without changing identity |
| Chemical properties | Results in the change of a substance’s identity |
| Physical vs Chemical Properties Examples : | Melting Point Flammability Density Magnetism Reactivity |
| Changes of Matter -Physical Change : | may change properties but doesn’t change composition |
| Changes of Matter -Chemical Change : | will change the composition of a substance |
| Physical Changes Examples : | Boiling Melting Freezing --------------------- Vaporizing Sublimating Deposing |
| Chemical Changes Example : | Burning Baking Reacting |
| Signs of a Chemical Change | Formation of… Heat Light Gas A Precipitate |
| Give 2 examples of how chemistry is used in your daily life. | Chemistry of Emotions. ... Chemistry in Food Production. ... |
| Elements consist of atoms of the same type | H, He, Fe, O, etc... |
| Compounds are formed when atoms chemically bond to one another in a specific way | H2O, CO2, C6H12O6, etc... |
