A 46.2-mL, 0.568 M calcium nitrate [Ca(NO3)2] solution is mixed with 80.5 mL of 1.396 M calciumnitrate solution. Calculate the concentration (in M) of the final solution.     Strategy Because the concentration of the final solution is less than that of the original one, this is a dilution process.Keep in mind that in dilution, the concentration of the solution decreases but the number of moles of the solute remains the same.    Note: Answers must be numeric, not alphanumeric—42, not forty-two.

Solubility between Organic and Inorganic Compounds Procedure:1. Prepare 2 transparent glasses, tablespoon, water, table salt, and cooking or vegetable oil.2. Place water in both glasses and make sure it is 3⁄4 full. Take note, they should have the same volume.3. Add 1 tablespoonful of table salt on the first glass and stir it using the spoon for 3 minutes.4. Add 1 tablespoonful of oil on the second glass and stir it using the spoon for 3 minutes.5. Observe the results. From the procedure above (you can search),-Describe the solubility of table salt in water based from the experiment. -Describe the solubility of cooking or vegetable oil in water based from the experiment. -Which of the compounds used is an organic and an inorganic? -Aside from solubility, what are the other ways to differentiate organic and inorganic  compounds? -Do all organic or inorganic compounds follow all their characteristic properties? Why or why  not?Own answer please and I would appreciate it if answers could…

Just want to confirm I got correct answer

Please, I want step-by-step solution

A stock solution of approximately 7.7x10^-5 molar will be provided in lab. Determine the volumes of each solution needed to prepare 50.00 mL of standard solutions of concentration 0.600x10^-5molar, 1.20x10^-5molar, 2.40x10^-5molar, and 3.00x10^-5molar. Round the calculated volumes to thenearest 0.1mL.

Macmillan Learning Suppose a student conducted an experiment similar to Experiment 3 using a green sports drink mix, preparing the solutions the same way. The green sports drink mix contains Yellow 5 dye and Blue 1 dye, but not Red 40 dye. At the Amax for the Yellow 5 dye, 420 nm, the student measured an absorbance of 0.187. At the Amax for the Blue 1 dye, 620 nm, the student measured an absorbance of 0.255. What is the concentration of the Yellow 5 dye and the concentration of the Blue 1 dye in the stock solution of the green sports drink?

EXPERIMENT 6 PRE-LABORATORY QUESTIONS DETERMINING THE SOLUBILITY OF AN UNKNOWN IONIC COMPOUND NAME DATE 1. Calculate the concentration, in grams of solute per 100 g of water, of a solution in which 7.462 g of solute dissolved in 25.50 mL of water. 2. Sketch two graphs, the first for a solid that's solubility is increasing as a funetion of temperature, and the second for a solid whose solubility decreases as a funetion of temperature. Be sure to label each axis. b) 3. After the first 7.00 mL, how many mL of distilled water are added to the test tube for each subsequent measurement? 4. How many decimal values can you measure with a buret? EXPERIMENT 6 107

Please correct answer and don't use hand rating

Show work, thank you! (Answer is not 5.5x10^-5) Need ICE table.

31 and 32 please

i got a answer for the a) is it correct the the pH need to be in pH 1 in order to dissolve both compound in which in acidic solution or charge ion where if it set 4 unit away from pka both compound it will be in acidic solution ? carbonyll will ( 4.8-4=0.8) and amine will (10.7-4=6.7) and different between 2 will be in 5.9 hence if pH =1 so amine will still in acidic rigth? . but for b) it state oposite which origin carbonyl in water while the origin amine in diethyl ether . and the question want the carbonyl in diethyl ether while amin ine water . so what should it do ? is it the pH still 2 unit away like ( pH around 6.8-8.7) how does it work that way ? it still at origin right ?
