 3.863 g of product mixture was isolated. The given image shows the GC with % area of the first peak (from left) at 55% and the second peak (from left) at 45% . The % yield of the reaction would be _______ %.

% error  is calculated on 

When running the reaction,   the starting material was found to be a liquid.  Per the reaction procedure,  you need  5.000 g of the material . You have an analytical balance, a micropipettor, a 100 mL measuring cylinder, a disposable plastic pipet (Berol pipet) at your convenience.  What are some methods to get the amount that you need in the flask ?

For the same reaction,  what is the theoretical yield in grams  ? 1. Mix 5 mL 1-phenyl ethanol (molar mass 122 g/mol, density =1.02 g/ml)  with 15 mL of conc. H2SO4 in a ______mL round bottom flask.2. Add a  boiling chip and gently swirl the contents and heat to boil in a reflux set up for 60 minutes .3.  Cool and collect the organic layer. Add CaCl2 was added. Stopper the flask and allow to  stand for 10 minutes with occasional stirring.4. Decant the product in a pre-weighed product bottle. Weigh the product and calculate the % yield.Analyze the product using GC, IR, NMR and chemical test.

The nurse is assessing a patient’s skin for signs of impaired skin integrity. The PCT is aware that which finding by the nurse is considered a major manifestation?

A 2×3 matrix times a 3×5 matrix is:

The system x’ = cos(x)x + sin(y)yy’ = cos(y)x + sin(x)y is linear.

The system x’ = 2x + 2y + 3y’ = -x + y + 1 is homogeneous.

I know that my camera is expected to show my face and my work area.

If A is a real 2×2 matrix and has eigenvalues λ, μ that are purely imaginary, then solution curves x(t) of x’ = Ax are always circles.
