1. An archeology student found a coin at a dig. She determined that the mass of the coin is 4.51 g and its volume is 0.49 cm?. Using the table below, what metal is the coin most likely made of? Name of Metal Density (g/cm) Aluminum 2.7 Zinc 7.1 Copper 9.0 Silver 10.5 Lead 11.4 Gold 19.3 A. Zinc B. Copper C. Silver D. Aluminum 2. Fireworks that contain metallic salts can generate bright colors. A technician investigates what colors are produced by the metallic salts by performing flame tests. Each metallic salt emits a characteristic colored light in the flame. Table 1: Flame Test for Different Metallic Salts Metallic Salt Flame Color Sodium Chloride Yellow Lithium Chloride Red Cesium Chloride Lilac Barium Nitrate Green Sodium Nitrate Yellow Lithium Nitrate Red If the technician tests an unknown metallic salt and sees a red color in the flame, what conclusion could be made? A. The unknown substance must contain nitrate. B. The unknown substance must contain chloride. C. The unknown substance must contain lithium. D. The unknown substance cannot be identified.
