You have been given a white powder that contains one of the following compounds What methods) would you use to identify whether you have compound I, J, or K? Be specific about the method, however you do not have to include the expected data from each experiment. What is the relationship between the compounds?
A white powder treated with diluted HCl acid dissolves quickly, and the reaction is featured with intensive bubbling. During a flame test of the resultant solution, the flame turns brick red in colour. From the chemical point of view, this white powder could be: A. Na2CO3 B. BaCO3 C. BaSO4 D. Na2SO4 E. CaCO3 The answer is E. CaCO3, but how would you determine this?
You have learned that adding table salt, NaCl (58.44 g/mol, 2.16 g/cm3), to water(Kb = 0.52 degrees Celsius/m) increases the temperature at which it boils. You decide to try cooking pasta faster at a higher temperature in boiling salted water. What increase in the boiling point do you expect if you add 1 tablespoon (1 tbsp = 14.8 cm3) of salt to one 8 oz cup of water (237mL)? (assume an ideal van't Hoff factor)
help me out please
lland 2.) You have a new set of automobile radiators to test, but had forgotten to obtain antifreeze/radiator coolant to do the test. Let's say your test radiators are cheap/disposable. Based on the material that you covered in Chapter 8 (colligative properties), you know that you can use salt or sugar to increase the boiling point or lower the freezing point. Therefore, you attempt to do a quick-and-crude test on the radiators using ordinary Table Sugar...
How could one make "white" light with atomic emissions? Thank you.
Both KCl and BaCO3 are white solids. If you were given a sample of either solid, describe how you would determine which one it is.
People commonly dissolve table salt (NaCL) into water that they are heating up. a) If you had a pot with 4 quarts of water (before heating) and add 1 teaspoon of salt, which is equivalent to 6.20g, what is the boiling point of the water? How much of an effect will that have on cooking pasta? (You can assume that NaCl fully dissociates. 1quart=0.946 L and Kb=0.51oCkg/mol for water) b) Would the cooking of pasta (based on boiling point) be...
Two firms (Natural Salt and Healthy Salt) compete in the market for Himalayan table salt Consumers see the salt produced by both firms as perfect substitutes. In this market, each firm chooses what output to produce and price is determined by aggregate output. Market demand is given by Q 450-2P, where Q is kgs and P is Ekg. The initial marginal cost of Natural s 506/kg. The respective for Healthy Salt is 40/kg. A process innovation in the production technology...
You have a powder that dissolves in water to form a strong acid. You dissolve 2g of the powder in 100ml of water, and measure the pH to be 4. You would like to form 100ml of a solution with pH 5. How many grams of the powder do you dissolve in 100ml of water? 0.2 g 0.4 g 20 g 40 g
