A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he used the ideas just developed in class about density. First he measured the mass of the metal to be 169.7 grams. Then he dropped the metal into a measuring cup and found that it displaced 16.0 mL of water.

Calculate the density of the metal.
Density =
g / mL

Use the table below to decide the identity of the metal. This metal is most likely
.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
