If you are trying to determine the identity of an unknown metal, why is density a...
1) Suppose you are trying to determine the identity of the metal ions in your unknown mixture for this lab and you find that after step 1 you have a precipitate. You separate the precipitate from the solution and perform step 2 (on the precipitate) and step 3 (on the solution). Your results of step 2 do not yield a precipitate. Your results from step 3 yield a precipitate. Which spot tests should you run to completely determine the identities...
Jordan obtains a silver metallic unknown. Jordan measure the mass of the metal to be 62.307 g. When the metal is placed in a graduated cylinder that contains 22.3 mL of water, the new volume is measured to be 29.1 mL. a) calculate the change in volume of water in the graduated cylinder. b) calculate the density of the metal. c) Jordan's teacher provides a list of possible unknowns. Determine the identity of the unknown. METAL DENSITY (g/mL) lead 11.35...

What is the effect on the calculated density of the unknown metal or liquid under the following conditions? After the flask was filled with unknown liquid the cover slip was placed on top. In doing so a small air bubble was trapped under the cover slip. When determining the density of the unknown metal, the flask was filled less than one quarter way with the metal instead of halfway. When determining the volume of the flask, the student did not...
3. A student was given an unknown metal. The student determined that the mass of the metal was 30.2 g. The student placed the metal in a graduated cylinder filled with 20.0 mL of water. The metal increased the volume of water to 22.9 mL. Calculate the density of the metal and determine the identity of the metal using the table below. Metal Density (g/mL) 11.3 Lead Silver 10.5 Nickel 9.90 Zinc 7.14 010000 Word
Assume that you have the same volume of aluminum and 80 g of an unknown metal. What is the density of the unknown metal if the Aluminum has a mass of 19 g and a density of 2.7 g/cm3? Can you determine which type of metal it is?
A student is determining the density of an unknown metal with a mass of 56.5 g. The student partially fills a graduated cylinder with water and measures the volume of the water by itself as 54.8 mL. The student then adds the metal to the water and measures the new volume as 87.3 mL. What is the density, in g/mL, of the metal?
What tests would you most likely perform to determine the identity of an unknown solid? option A: Conductivity option B: Density option C: Boiling point option D: Reactivity
An irregular lump of an unknown metal has a measured density of 5.33 g/mL. The metal is heated to a temperature of 157 °C and placed in a graduated cylinder filled with 25.0 mL of water at 25.0°C. After the system has reached thermal equilibrium, the volume in the cylinder is read at 33.7 mL, and the temperature is recorded as 37.8 °C. What is the specific heat of the unknown metal sample? Assume no heat is lost to the...
