Answer:
Aqueous layer (1 M HCI)
Explanation:
First of us I want to remind you of the cliché in chemistry that like dissolves like. In solvent extraction, a mixture is dissolved in a system consisting of two immiscible solvents. One layer is organic while the other layer is aqueous.
Polar substances partition in the aqueous layer while nonpolar substances partition in the organic layer.
Since Copper sulfate is ionic, we will find it in the aqueous layer according to the old chemistry cliche.
It's B. Since density equals mass/volume. The missing quantity needed is mass.Hope this helps.
I am pretty sure that the effect on the volume of 1 mol of an ideal gas is being revelesd by the option : B. The pressure changes from 760 torr to 202 kPa, and the temp. changes from 37degrees C to 155 degrees kelvin. I choose this one because you have to use ideal gas law - V= nRT/P and you will see the doubled pressure in here : <span>760 torr= 1atm and 202kPa = 2 atm.
Do hope it helps! Regards.</span>
<u>Answer:</u>
<em>The final volume must be 400 mL.</em>
<em></em>
<u>Explanation:</u>
Let us assume the Initial volume as 100ml
Using dilution factor formula
So,
Thus, the final volume must be 400 mL.
CO2: 12.0107 + 15.9994(2) = 44
NH3: 14.0067 + 1 (3) = 17
1.55 (17/44) = .599g
