  1. Welcome to Chemistry 1110

  2. The Study of Matter • Matter - Occupies Space and has mass

  3. The Study of Matter • Matter - Occupies Space and has mass • Mass - Measure of the quantity of Matter

  4. The Study of Matter • Matter - Occupies Space and has mass • Mass - Measure of the quantity of Matter • Weight - Measure of the force of attraction

  5. The Study of Matter • Matter - Occupies Space and has mass • Mass - Measure of the quantity of Matter • Weight - Measure of the force of attraction • Physical properties - Characteristics of the substance. (Color, Hardness, Density, Etc.)

  6. The Study of Matter • Matter - Occupies Space and has mass • Mass - Measure of the quantity of Matter • Weight - Measure of the force of attraction • Physical properties - Characteristics of the substance. (Color, Hardness, Density, Etc.) • Chemical Properties - How one substance reacts with another.

  7. ENERGY The capacity for doing work Or The ability to change matter

  8. ENERGY The capacity for doing work The ability to change matter • Potential energy - Energy due to position

  9. ENERGY The capacity for doing work The ability to change matter • Potential energy - Energy due to position • Kinetic energy - Energy due to motion

  10. ENERGY The capacity for doing work The ability to change matter • Potential energy - Energy due to position • Kinetic energy - Energy due to motion • Chemical energy - The energy released as a reaction occurs

  11. The States of Matter • Solid - Maintains shape and volume

  12. The States of Matter • Solid - Maintains shape and volume • Liquid - Maintains volume, takes the shape of the container

  13. The States of Matter • Solid - Maintains shape and volume • Liquid - Maintains volume, takes the shape of the container • Gas - No definite volume, takes the shape of its container

  14. MATTER • Pure substance - Has fixed composition and distinct properties

  15. MATTER • Pure substance - Has fixed composition and distinct properties • Element - Substance that cannot be broken into a simpler substance without loosing its properties

  16. MATTER • Pure substance - Has fixed composition and distinct properties • Element - Substance that cannot be broken into a simpler substance without loosing its properties • Compound - Composed of two or more elements

  17. MATTER • Pure substance - Has fixed composition and distinct properties • Element - Substance that cannot be broken into a simpler substance without loosing its properties • Compound - Composed of two or more elements • Mixture - Composed of two or more substances which retain their individual identities

  18. MATTER • Mixture - Composed of two or more substances which retain their individual identities • Homogeneous mixture - Mixture that is uniform throughout

  19. MATTER • Mixture - Composed of two or more substances which retain their individual identities • Homogeneous mixture - Mixture that is uniform throughout • Heterogeneous mixture - Mixture that is not uniform throughout

  20. The Chemical Element • The letters on the periodic table are like the alphabet to chemists

  21. The Chemical Element • The letters on the periodic table are like the alphabet to chemists • Each Element has distinct properties

  22. The Chemical Element • The letters on the periodic table are like the alphabet to chemists • Each Element has distinct properties • When elements combine, they are written with subscripts indicating how many of each element there is.

  23. The Chemical Element • The letters on the periodic table are like the alphabet to chemists • Each Element has distinct properties • When elements combine, they are written with subscripts indicating how many of each element there is. • To explain how elements react, a chemical equation is used

  24. The Chemical Element • The letters on the periodic table are like the alphabet to chemists • Each Element has distinct properties • When elements combine, they are written with subscripts indicating how many of each element there is. • To explain how elements react, a chemical equation is used • If two of the same element combine, it is called a diatomic molecule.
