The column dimensions were 10 in. in the north-south direction (denoted as y-direction on the confined concrete column cross-section) and 15 in. in the east-west direction (denoted as x-direction on the confined concrete column cross-section). A concrete cover of 0.75 in. was used on all sides of the confined concrete column. Eight ASTM A706 Grade 60 #7 deformed steel bars were used for the longitudinal mild steel reinforcement bars inside the confined concrete of the column.
The Controlled Variable for this experiment was mass and volume. When identifying an unidentified object finding the density is the easiest way to do it because, any pure substance has a specific density at a specific temperature and each element and compound has a unique density associated
As seen in table 1, the theoretical yield was .712 g of C_17 H_19 NO_3. The % yield of this experiment was 7.51 % of C_17 H_19 NO_3. . This low yield can be explained from a poor recrystallization technique combined with potential contamination. Throughout the experiment, the mixture changed color from green, orange, to yellowish lime, and eventually clear.
With background knowledge of chemistry, it is known that aluminum also has a molecular weight of 26.981 g/mol, which then lead to the reaction of 0.0374mol of aluminum. The first reactant was a redox reaction, formed through aluminum, adding potassium hydroxide and water to yield potassium aluminum hydroxide, plus hydrogen. During the process of this reaction, there was many changes occurring. The color of the reaction turned grey at first then eventually turned black. The solution was also evaporating due to the use of the fume solution.
He had drawn the interiors of rooms and labeled them and specified their dimensions, down to inches, in his precise, blocky
2- Your View Point 2 also in hs2 it is stated that the scale
Act Two Scene V & Vl Major characters: Cyrano and Roxane Minor character(s): The Duenna Scene V Cyrano, Roxane, and the Duenna Cyrano: I’ll give her my letter with the slightest opportunity! (ROXANE, masked, appears behind the glass of the door, followed by the DUENNA. Cyrano goes to open the door.) Come in!
The incision would be thought of as large, but with the visual representation it can be shown just how large it is and that for an opening about half the size of the abdomen the descriptor used is quite
Joints are appeared with chiseled lines and the artists utilized an outline plan where three equivalent circles characterized the type of the figures. The marble figures were hued with painted themes, which could have identified with the arrangement of bodies for internment.
In figure 2, the presenter provided us with accurate information on it, but I would have tried to tie each different panel back to the main point of the article. The presenter stated that panel B is a table of the amino acid sequences. Why was this figure so important in the article? What was the researcher trying to demonstrate by showing that the amino acids were conserved in all those sequences ? Personally, I would have ended this slide with a conclusion.
During the Han dynasty, around 142 AD, a man named Wei Boyang was the first to come up with the idea of gunpowder. By 300 AD, a scientist named Ge hong wrote and explained the ingredients and explosion of gunpowder. It is a mixture of sulfur, charcoal, and saltpeter. Potassium nitrate can also be replaced with saltpeter to make gunpowder. It was not until the Tang Dynasty, around 700 AD, when the real idea of using gunpowder was actually thought of.
The results of the phenol-sulfuric acid analysis conducted in this experiment suggest that the data acquired was relatively precise but inaccurate with respect to the given carbohydrate concentrations of the soda and Gatorade samples. Using a standard curve generated from a glucose solution with a known concentration, the carbohydrate concentration of the samples was determined (in terms of glucose) and a low coefficient of variation was calculated. However, a high percent relative error was apparent in the analysis of both samples. This may have been due to the fact that the analysis was conducted assuming glucose was the carbohydrate of interest, while, in fact, a significant portion of the monosaccharides would have existed as fructose (a
