4. What is the difference between extensive and intensive proper es? (a) Both properties exhibit mass, volume, and density as an independent variable. (b) Intensive property is the property that depends on how much of a substance or solid is present (c) Extensive property is the property that is independent on how much of a substance or solid is present. (d) An example of an extensive property is mass and volume; An example of an intensive property is density 5. When facing the periodic table, where is theå ®and-p-blocks generally located? (a) In the middle of the table and the left of the table (b) To the left of the table and to the right of the table (c) Along the stair-step line (d) None of the above 6. How many significant digits are in 6.? (a) 0 (b) 2 (c) 3 (d) 6 (e) None of these 7. What is the correct formula for octaphosphorous tetraoxide? (a) P4020 (b) P.Og (c) P,O4 (d) P20s 8. An irregularly shaped solid has a mass of 40.0 g. When a student places it in a graduated cylinder containing 15.5 ml of water, the student could not accurately see where the meniscus rose. Before he forgot the final volume, he calculated the density to be 14.7 g/mL. Use this information to help see where the final level of the meniscus rose. Report your answer using the correct significant digits.) (a) 82.0 mL (b) 20.0 g/ml (c) 50.0 g/mL (d) 35.5/mL
