- Ceramics used as abrasives must be hard and tough and be able to withstand high temperatures that arise from frictional forces. What is the minimum required hardness (measure in Mohs scale) for a material to be used as abrasive? Your answerA mixture of water (D = 1,000 kg/m3) and alcohol (D = 791 kg/m3) has a density of 920kg/m3. Is this mixture mostly water or mostly alcohol? Explain why.What volume of 95.0% alcohol by weight (density: 0.809g/cm^3) must be used to prepare150 cm^3 of 30.0% alcohol by weight (density: 0.957g/cm^3)
- 3. True/False: Carbon dioxide in water is an example of a liquid in gas solution.Determine the mass of the water in the sample based on the following data to teo decimal places. Mass of crucible and cover- 50.02 Mass of crucible, cover and sample before heating-51.04 Mass of crucible, cover and sample after heating-50.86Solid particles in water may exist in 3 ways - dissolved, dispersed, or suspended. (True/False) When a previously dissolved solid separates from water either via chemical reaction or a change in certain condition like pH or temperature, it forms a______.
- 5. (optional) Blue turquoise is an example of a hydrate mineral containing copper; the chemical formula is CuAl6(PO4)4(OH)8•4H2Ó. What is the percent water in this semiprecious stone?Cinnamaldehyde (132.16 g/mol) is used as a flavoring agent. What mass of cinnamaldehyde must be added to 325 g of ethanol to give a solution whose boiling point is 81.47°C? (For ethanol, Kb = 1.22°C/m; boiling point of pure ethanol = 78.37°C)The solubility of (NH4)2SO4 in water is 75.4 g of (NH4)2SO4 per 100 g of water. 62.2 g of (NH4)2SO4 are added to 79.0 g of water. How many grams of (NH4)2SO4 dissolved in the water (write your answer with three significant figures)? g.

- (a) Does the diagram best describe a crystalline solid, a liquid,or a gas? (b) Explain.Before slow cooking a meat (for example, in a crockpot/slow-cooker) you will often find instructions to sear the meat on high heat in an oiled skillet for a few minutes before transferring it to the crockpot. The searing is brief – not long enough to cook the meat thoroughly. Despite myth/legend, the searing will not “seal in the juices”. What is the searing for?The solubility of (NH4)2SO4 in water is 75.4 g of (NH4)2SO4 per 100 g of water. 34.2 g of (NH4)2SO4 are added to 49.4 g of water.
