27. Identify each of the underlined phrases in the following account of a laboratory
procedure as either a chemical change or a physical change. Explain your answers.
The unknown substance was tested to determine its properties. First, a sample
was ground up finely with a mortar and pestle. Next, samples were dissolved
in water and other solvents. A Bunsen burner was lighted and some of the
pure chemical was placed into a test tube and heated gently until it melted.
Because the heating was too rapid, the test tube cracked and the experiment
was repeated. Heating was continued this time until the substance boiled.
Some fumes of the boiling substance reacted with oxygen in the air to form a
white powder.
28. What are the element symbols for calcium, sodium, gold, and silver? Write the
names for the elements having the following symbols: S, N, Cu, Fe.
29. List and describe the evidence of a chemical change. ( Give examples for each
evidence)
30. Compare the properties of metals, nonmetals and semi- metals ( metalloids or
semi –conductors)
