  1. A change in position with respect to a reference point Acceleration Velocity Direction Motion Because calcium can combine with other substances but cannot be changed into a simpler substance by an ordinary chemical process, calcium is classified as A compound A mixture An element A gas

  2. You do not know an object’s velocity until you know its • Speed and distance • Reference point • Speed and direction d. Acceleration As you move from Group 1 to Group 18 on the periodic table • The elements go from highly reactive to non-reactive • The elements are mixed up • The elements go from non-reactive to highly reactive • The elements are in alphabetical order

  3. If you know a car travels 30 km in 20 minutes, you can find its • Acceleration • Average speed • Direction • Instantaneous speed The chemical formula for sulfuric acid is H2SO4. Which of the following best describes sulfuric acid? • An element made up of atoms • A compound made of elements • A mixture made up of elements • A mixture made up of compounds

  4. Acceleration is a change in speed or • Time • Slope • Direction • Distance The atomic number of an atom is determined by the number of • Protons • Electrons c. Neutrons d. Isotopes

  5. The rate at which velocity changes is called • Acceleration • Constant speed • Average speed • Velocity In the modern periodic table elements are arranged • According to atomic mass • According to atomic number • In alphabetical order • According to the number of neutrons in the nuclei
