Question

1) Use the items in the space below to construct a flow chart for the procedure you will use to create a iron nitrate solution during the incestigating of Iron Thiocyanate laboratory. Not all items must be used.

2) Use the procedure in the "Introduction to Spartan" experiment to fill in the blanks for the given molecules below. Make sure to Minimize before performing the calculation. Bond Angle 1 for CHCl3 is the Cl-C-Cl bond and Bond Angle 2 is the H-C-Cl bond.

Select the items below that are true You will lose points if you make too much dilute Fe(NO3)3 solution. Step 2 Dissolve and dilute with It is not important to record the exact mass of Fe(NO3)3 that you weigh out, as long as it is near 0.8g 0.1 M HNO3(aq) should be added until the bottom of This process creates a | meniscus is parallel to the calibration line on the neck of the volumetric flask Step 1 If you weigh out 0.770 g Fe(NO3)3 9H20, what is the final concentration of the -0.2 M Fe(NO3)3 solution that you make? 0.1 M HNO3 (aq) DI H20 () 2 M Fe(NO) Number -0.2 M Fe(NOals solution Place-0.8 g Fe(NOala into a 10 mL volumetric flask

Explanation / Answer

For Question 2 and 3, it's neccesary that you follow the procedure in there. I don't know if that is a program for a PC or an app. So If you don't mind please send me in a comment the "Introdution to Spartan" experiment so I can read it and try to understand it.

For Question 1:

In the first blank, put the image of the Fe(NO3)3 solid (The white powder), in the next one put the image of the empty volumetric flask.

Then where it says "Step 1" put: Place 0.8 g Fe(NO3)3 in a 10 mL volumetric flask.

In step 2, put: H2O (l)

then, put the image of the volumetric flask with 0.2 M Fe(NO3)3, and in the final blank where it says "This process creates a, put 0.2 M Fe(NO3)3 solution.

Now if you use 0.770 g the final concentration of Fe(NO3)3 would be:

moles = 0.770 / (55.8 + 3x14 + 9x16 + 9x18) = 1.9069x10-3 moles

M = 3.973x10-3 / 0.01 = 0.1907 M

If you need anything else, or something to be fixed, feel free to tell me in a comment, along with the introduction to spartan experiment so I can help you with both of them.
