It can been seen that there are two distinct bonds, between two oxalates (94.06°, 93.56°, 90.61°, 94.30°) and within a singular oxalate (81.30°, 82.63°). The reason these bond angles vary within this octahedral complex are a result of lone pair repulsion creating slight variations among the bonds. Color Determination: To explain the coloring of Potassium Tris(Oxalato)Ferrate(III) Trihydrate, we must take into account λmax. Potassium Tris(Oxalato)Ferrate(III) Trihydrate had a λmax of approximately 395 nm, and formed yellow green crystals. When we look at a color wheel it can be seen that a substance with a λmax of approximately 395 nm would absorb violet light.
9. Theoretical yield = (150.22g/mol)(3.5 x 10^-3 mol of nucleophile) = 0.525 g Actual yield = 0.441 g, Percent Yield = (0.441g/0.525g) x 100% = 84% 10. Percent recovery from recrystallization = (0.172g/0.441g) x 100% = 38% 11. The data table provided below obtained melting point data for crude product, pure product, and mixture of the pure and 4-tert-butylbenzyl. 12.
To find the volume of the quarter shaped tank you would have to use the volume of the sphere using the equation V=4/3(3.14)r^3. You would substitute the radius of 70 feet into the equation, V=4/3(3.14)(70*70*70). You would multiply the radius 3 times since it's the radius cubed. Once you use a calculator to solve it and you get the answer 1,436,026.67 feet. That's just the volume of the quarter tank so the find the volume of the main tank you would divide 1,436,026.67 by 4
We calculated the density of the metal ball to be 7.83 g/cm3 using methods IV and V and concluded it was iron. C. The density of the plate was calculated to be 2.667 g/cm3 using methods IV and V. Thus we concluded that it was aluminum. 3. When calculating density for the rod and the ball, two different volumes were used: 1. calculated and 2. displacement method. Which result do you thing is better and why?
Use the following formula to determine the confidence interval: (x ̅-t_(α/2) (s/√n),x ̅+t_(α/2) (s/√n)) t_(α/2)=t_0.025=2.045 Substitute the values into the formula: (14.87-2.045(0.5503/√30),14.872.045(0.5503/√30)) = (14.665,15.075) The calculation above clearly states that the confidence interval at 95% confidence is approximately 14.665 - 15.075 ounces. Step 3: Crete a hypothesis to test the claim that a bottle contains less than sixteen ounce is correct. Be sure to clearly state the logic of the
The columnar epithelial cell is rectangular which is tall sides in length but shorts sides in width. Squamous cell is smooth, erratically and unevely formed. cuboidal epithlial cell is shaped similar to small cubes. yes, it is. Stratified squamous cell changes to a flatter figure which is creating a smooth barrier on the skin 's outermost layer.
Therefore 11 would be 1 dot over two horizontal bars, or 15 would be 3 bars. All numbers after nineteen would be written in powers of twenty, and when reached to the 400s it would be different as well. So the number 23 would consist of one dot on top of three dots following two bars. The number 429 would be written as one dot, on top of another single dot, atop of four dots following one
Non-metals cannot conduct electricity or heat very well. As opposed to metals, non-metal elements are very brittle, and cannot be rolled into wires. The non-metals exist in two of the three states of matter at room temperature gases and solids. Alkali Metals are made up of six different elements and are found in group one on the periodic table. These metals have only one electron in their outer shell.
The SEM images (Fig. 2) showed that FeMPn has a non-homogeneous and uneven surface, as well as the size of FeMPn that tended to vary due to aggregation. However, based on TEM image (Fig. 3), FeMPn has spherical in shape with the smallest particle of 30.5 nm. A non-homogeneous of
So, F + V − E = 7 + 8 − 13 and the answer would be 2 which is the expected outcome. Another way to prove the formula does not work for all solids is to take a Icosahedron and connect 2 opposite corners. Joining both corners, the solid will be a Icosahedron but it is not a convex polyhedron. As the soild is not a convex polyhedron should not be 2. So, F + V − E = 20 + 11 − 30, getting the answer as 1 which proves the generalisation F + V − E = 2 does not work.
