I’ve tried and tried to do this but now I’m stuck. Using the Virtual Lab
You have a summer internship working in a jewelery laboratory where your job is to explore the properties of
some alloys of silver, rhodium, titanium and platinum in order to make brighter jewelry at a lower cost.
One day while preparing an alloy, you accidentally left three bottles near the melting furnace and the labels
became charred and unreadable. OH NO! You now have three unlabeled bottles of metals. Your task perform
experiments to identify the metals in each of the bottles.
From a chemical handbook available in your lab, you find the following densities:
Metal
Density (g/cm3)
titanium 4.506
silver
10.5
rhodium
12.4
platinum 21.45

14. many depressants reduce small muscle control, making it harder for a. you to steer b. your mind to consider complex problems c. the eye to scan, focus, or stay still d. the kidneys to filter alcohol out of the bloodstream

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
