Matti is given two bottles of copper (II) sulfate solutions in her senior high chemistry lab. She is told that one bottle contains a saturated solution and the other one contains an unsaturated solution. The solutions are the exact same color and have no particles in the bottles. Describe what Matti can do to distinguish between the two solutions. A- 米 U X2 x? #3 X Next page age You are logged in as Kaylee Krys (Log out) VLL Chemistry CP 2021-2022 (Fickett).

Need help on all of them. It is mu first time taking chemistry so I am stuck on what to do. Thank you

Aluminum-lithium (AI-Li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. A commercial aircraft skin material having a density of 2.65 g/cm? is desired. Compute the concentration of Li (in wt%) that is required. The densities of aluminum and lithium are 2.71 and 0.534 g/cm3, respectively.

Step 2: Identify the dimensions of the quantities involved The second step is to identify the dimensions of the quantities involved in the problem. For example, if the problem involves distance, time, and velocity, the dimensions of these quantities would be length, time, and length/time, respectively. Step 3: Check if the units cancel out The third step is to check if the units cancel out. To do this, multiply the quantities together and check if the units cancel out, leaving only the desired unit. For example, if you are trying to find the velocity of an object and you know its distance and time, you can multiply distance by time to get velocity. If the units cancel out, you have a physically meaningful result. Step 4: Check if the result makes sense, to do this compare the units of the result with what you would expect based on the Robles statement.   Using the step hints above, answer the question. You do not have to solve. Just imagine that you're teaching a friend how…

An impure sample contains 1.01 g of impurities and 4.92 g of benzoic acid.  The impure sample is dissolved in water, then heated.  The solution is then cooled.  How many grams of benzoic acid will recrystallize when the solution has cooled? Include the unit and two decimal places in your answer. The solubilities of the impurity and benzoic acid in hot water are found as an item in the Recrystallization Experiment folder.   Solubility Data for Report Questions 10  Compound Cold Water solubility Hot Water Solubility Benzoic acid 0.42 g per 100 mL of water 5.79 g per 100 mL of water Impurity 0.61 g per 100 mL of water 4.62 g per 100 mL of water

Which answer choice best describes a heterogeneous mixture?     A solution with different sized particles A solution that exhibits the Tyndall effect Mixtures which have a non-uniform composition Mixtures which have a uniform composition
