Mole

Toad’s actions are concerning to the other animals as a result of this. The animals are given a code which Mole follows religiously. The code is never given, as if the reader is supposed to know the code (if the reader belongs to the same class) or not allowed to know the code (if the reader belongs to a lower class). This animal code is why Toad’s eccentric…

the experiment is determined utilizing a back titration, in which the bromine is reacted with bromate. One mole of bromate produces three moles of bromine and the excess amount of bromine is determined by converting an excess of I- to I2, with potassium iodine, in which iodine is determined using a back titration. One mole of Br2 produces one mole of I2 and one mole of I2 requires two moles of S2O32-. 1. Dry 1.5 g…

the two parts of stoichiometry, the composition and the reaction. Section I. Molar Mass is the sum of the masses of the atoms that make up the formula. (i.e. Aluminum Sulfate Al2(SO4)3 has a molar mass of 342g/mol. The unit g/mol is read as grams per mole). Table 1.1 Atomic Masses of…

From Fe2(SO4)2, we simplify it by using the formula: molecular/empirical. Interpret Research: The answer to “Which Iron Is It?” is Fe (II). The mole ratio of iron lost to copper expected for Fe (II) is 1:1 while the mole ratio for Fe (III) is 3:2. According to our data from the experiment, the mole ratio was 0.93, which translates to 1 when it rounds up to one significant figure. The mass of the iron sample changed during the process because a single replacement reaction…

This statement may surprise those whose primary knowledge about Mexican food is tacos and burritos. Mole is Mexico’s national dish. It is served at important celebrations like weddings and baptisms. Red mole has more significance than a national dish; however. Even the very Nahuatl word “mole,” which means sauce, shows a connection to Mexicans roots from the past, dating back to the Aztecs. This dish is the perfect example of how food identifies…

where the Mole is having his annual spring cleaning in his little home. Suddenly, he hears something that calls him to go up above. As he saw the outside world, hearing the birds chirping and feel the sunshine, he realized how much time he was spending underground especially during the times when the weather was good. Looking at the surroundings he decided to explore, until he reached the hedge. There he saw several rabbits and blocked the way asking for money in order to let the Mole pass in in…

A colorimeter measures the absorbance of particular wavelengths of light by a specific solution. How much light is absorbed depends on the concentration of a substance (the amount of moles). This implies that, when the absorbance of an unknown concentration is measured, it is possible to detect the amount of moles…

940 are estimated to die from it in 2015. There is a greater risk of melanoma for anyone that has more than 100 moles. For characteristics of melanoma, there are new moles, evolving moles, and existing growths that change/grow remarkably. There are also lesions that can either itch, change, bleed, or don't heal. If a mole is asymmetrical then it is a warning sign for melanoma and the moles can be any color and are usually have a large diameter. The causes of melanoma happen when mutations occur…

Discussion The findings in this lab show that the melting point of Alum is 92.5 degrees Celsius. During the first trial a temperature of 91.0 degrees Celsius was recorded, but during the second trial a temperature of 93.0 degrees Celsius was found. Averaging the two temperatures gives a total around 92.0. The literature melting point of Alum is said to be 92.5 degrees Celsius and the data from similar studies, such as, Chemistry 103: Synthesis of Alum, together show that the results from the…

expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of thermodynamics is that energy can’t be created or destroyed. Based, off of Google, the second law of thermodynamics is that “entropy in the universe can never be negative”. They…
