  1. Look at the lab glassware below. Identify all of the glassware that can be used to measure volume with the greatest accuracy. Write your list. Graduated Cylinder Volumetric flask Erlenmeyer flask Pipette Beaker

  2. Classify the following as a substance or a mixture • Soda • Ammonia • Iron • Seawater • Air

  3. Identify the following as either Chemical Change OR Physical Change • alcohol evaporates • Photosynthesis • Dry Ice subliming • Burning Gas • Melting Gold

  4. Below is a list of separation techniques. Identify which technique would be the best to separate the following mixtures. Place the letter of the correct answer. Mixtures Separation Techniques Chromatography Distillation Vaporization Filtration Decanting Centrifuge • Separating blood into white blood cells, red blood cells, and plasma • Separating a mixture of sand and salt • Separating a mixture of salt and water • Separating a black ink mixture into its different colors

  5. Identify the following as either a Chemical Property OR Physical Property. • Water has a density of 1.00 g/ml • Lithium is silvery white/grey in color • Magnesium combines with oxygen and forms magnesium oxide • Mercury is a liquid at room temperature

  6. Use the following balanced equation to answer the questions below: 4Al(s) + 3O2(g) → 2Al2O3(s) • What does the (s) stand for? What about the (g)? • Of the 4 substances listed, identify the substance in the equation that cannot be broken down by a chemical change and explain why.

  7. Chemical Property vs Physical PropertyHow are they Different? Explain the difference between a chemical property and a physical property. Give at least 2 examples for each.

  8. Volume vs Freezing PointHow are they Similar? Explain the similarities between volume and freezing point. In your explanation, you MUST use the terms properties of matter, intensive, extensive, and help identify. Underline these terms in your answer.

  9. . Classify each mixture as either Heterogeneous of Homogeneous. Mixture A:____________ Mixture B: _______________ Calculate the VOLUME of the Lead pellets used in Mixture B. Report your answer using correct significant figures and the correct unit. Show all work. Describe a procedure to physically remove the water from Mixture A.

  10. Identify the following as either an Extensive Property or Intensive Property • Mass • Density • Melting point • Volume

  11. Identify how many significant figures are in each number. 1) 0.0031 cm 2) 2009 miles • 500 in • 30. m • 45.00 g

  12. MSDS • What do each of the colors on the NFPA diamond represent?(Blue, yellow, red, white) • What does a 4 on the red section indicate?
