atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl = 2AlCl3+ 3H2. The reaction produces two moles of aluminum chloride and three moles of hydrogen gas. The aluminum donates its valence electrons to become aluminum chloride During this reaction…
Conclusion: After observing the evidence that we received from this experiment it is clear that the results thoroughly support my hypothesis. Within my hypothesis I had stated that the melting order from first to last was, as follows, paraffin, glucose, sucrose, and finally, salt. The results that we gathered supported this exact hypothesis. The first substance to melt was indeed paraffin and the second was glucose, and then sucrose and finally salt. The results are supported by the basic…
In this lab, benzoic acid, benzocaine, and 9-fulorenone are isolated from a three-component mixture by using the acid-base extraction and other following types of various extraction techniques. An acid-base reaction is utilized in order to isolate the individual species from the mixture. First, in isolating the base benzocaine, proton transfers occurred via reaction with hydrochloric acid, which led to a significant shift in the polarity of the said compound, although the conjugate acid of…
1)Hands were washed thoroughly with soap and water to ensure that no contamination on the coli-MUG tubes. The sealed plastic package was opened and coli-MUG tubes were removed. 2)Usually, inner fermentation vials contain only air. The assemblies was inverted and inner vials were allowed to fill with air, only if these inner vials contain any liquid. 3)Cap was removed and it was ensured that open end of the tube or the inside of the cap did not open. 4)Each of the given tubes were dispensed with…
and feed a growing population, food companies add harmful chemicals and hormones to speed growth and increase production. This is a an epidemic because everybody is exposed to different kinds of chemicals and food chemicals are the most common. Due to increase in cost for maintaining our food healthy, adding chemicals and hormones drops the price, but has negative affects to the human body internally when consumed. Many different chemicals are added into the food we consume or sprayed on our…
In this week’s reflection video, I, learned about the weapon printing design done by the process of hydro-graphics. In the video a rifle stock is used with a Dip Wizard hydrographic kit to add a camouflage pattern. The Dip Wizard’s Kit just like other hydrographic kits uses a technique of applying a printed pattern such as; camouflage or any other pattern to a 3-dimensional object. This process goes by the terms; hydro-graphics, hydro-dipping, image transferring, immersion and water print…
DISCUSSION It is clear from the very low fraction of “head-to-head” linkages that this reaction is far less energetically favorable than the “head-to-tail” reaction, which occurs normally. The head-to-tail arrangement is preferred energetically due to steric and resonance effects. When the radical attacks the fourth (double-bonded) carbon, the new radical that is produced is more stable, as it may participate in resonance with the neighboring oxygen. Conversely, when the radical attacks the…
Questions: (a) Show that: (b) What value of ε ss would you expect at 800°C and 16000 psi? A= 0.0043 Using your Larson-Miller curve, what temperature should you use for a life of 20 years at the lowest stress level? For the extensive length of time, a temperature of approximately 25 oC which is close to room temperature. With increasing stress or temperature, what changes will you notice in a typical creep curve? When you increase temperature or stress, the creep curve will increase in…
An increasing number of pets are being diagnosed with Canine Atopic Dermatitis, the technical name for itchy skin. This condition is most often caused by a hypersensitivity to either food or environmental allergens, including pollens, molds, dust mites, and insect antigens (Becker). Some animals suffer with itchy skin and lesions while others don’t, and there could be many reasons as to why this happens. However, it has been found that it may have to do with how well the skin functions as a…
The garnet ferrites have the general formula RFe5O12, where R is one of the rare earth metal ions (Y, Gd, Dy, Sm, Eu, Ho, Er, Tm, Tb and Lu). The first trail for synthesis of garnet Yttrium ferrite (Y3Fe5O12) was done by Bertaut and Forret in 1956 [39], this trial was followed by another one in 1957 when Geller and Gilleo prepared and investigated Gd3Fe5O12 [40]. The garnet ferrites have complex crystal structure with cubic shape. The cubic unit cell of garnet ferrites R3Fe5O12 contains 8…
