Sara did a lab that required her to make many observations about an unknown substance. Read her lab
journal notes and then determine the physical properties and chemical properties she observed. Then
write those in the T-table provided below.
The substance is smooth in texture and silver in color. It is a solid cube that measures 2cm, by 1cm, by
1cm. It was placed in water and did not react. Its mass is 3.25 grams. The substance can be held
without gloves and does not harm skin tissue. The substance was placed on a hot plate and began to
melt to a liquid at 421°C. The solid cube was hammered and did flatten into a thin long rectangle. The
substance does conduct electricity but not especially well. The substance did not hold a flame when
attempted to ignite.
