Ethanol fermentation

The unknown base concentration of a sodium hydroxide solution can be determined by titration potassium hydrogen phthalate (KHP) with an unknown concentration of sodium hydroxide NaOH. The average molarity of NaOH determine by the moles and volume of the KHP and NaOH. (Eq 1). KHC8H4O4(aq) + NaOH(aq) = H2O(l) + NaKC8H4O4(aq) (Eq 1) The unknown concentration of white vinegar can be determined by the white vinegar with the known concentration of…

1. Existing knowledge, research and views: The separation of the sulfur and iron powder was accomplished through magnetism. When combining the sulfur and iron powder to form a mixture, a magnet can be used to attract the iron separating it from the sulfur. Unlike the iron and powder, the salt and sand were separated through filtration. This is a method which separates solids from liquids. In the experiment, the mixture of salt, sand and water are separated as it is poured through a funnel with…

According to the textbook on page 440, the reform groups were led by dreamers and activists who saw immortality or social injustice and wanted to fight to correct the situation. After the American Revolution many Americans drink way more than they should. Alcohol played a huge role in society from wedding ceremonies to elections. That was until many became a part of the movement Temperance. The Temperance movement begin to solve the alcohol problem that was spreading because in the beginning it…

morning of January 17, 1920, “ordinary events like taking a bottle of wine to a friend’s house, sipping a drink in public or selling a beer were now illegal from coast to coast, punishable by up to six months of jail time and a fine up to $1,000” (Blumenthal 59). Americans were still reluctant to give up their favorite drinks. It was legal to make cider and beer at home as long as no alcohol was added. Beer could even be sold if most of the alcohol if most of the alcohol content was first…

While the list had a very large number of different materials that were located in the shop, I only will list the chemicals that would present an industrial health hazard to an employee using them and chemicals that are used in every battery repair. Since some repairs use different chemicals and different processes, I decided to narrow it down to a very basic battery repair that would be done at the Fairmont shop I visited. First would be sulfuric acid, which is used in the cells of the battery…

The goal of this study was to explore and set up a new way of working with the introduction of an additional service. This service was to close the gaps of inequality in care and the missed change to involve patients in their future planning for recovery. With this in mind the return appointment system for patients who deliberately self-harm was extended to include patients who were intoxicated, out of hours and voicing thoughts of self-harm, but not suicide. Despite these intentions, there is…

As a result, lactose is a competitive inhibitor. In the presence of the inhibitor, the slope of the Lineweaver-Burk plot becomes the equation below. Using equation 7 along with the Km and the Vmax from series A, the Ki of Series B and C were calculated. The concentration of inhibitor for 50mM lactose was found to be 35714 μM using equation 1. Similar to the substrate concentration, the inhibitor concentration can be found using the same equation, but substituting in the inhibitor molar…

In this experiment, 25 g of solid sodium acetate trihydrate was added into a large beaker. The solid was then heat for 5 minutes, where liquid formed. 6.3 mL of water and a pinch of red dye was poured into the beaker while heated for 2 additional minutes. The solution was then cooled in an ice bath for 30 minutes. The solid-liquid product was then finally poured on a pinch of sodium acetate trihydrate crystal seeds to form ethanoic anhydride. This experiment was ultimately conducted in order to…

Queso Fresco Lab Report 1) The first step to making Queso Fresco is to mix 2 cups of cultured buttermilk with 4 cups pasteurized whole milk. Next, heat the milk to 90°F and prepare the Junket Rennet while the milk is heating. To prepare the Junket Rennet place 1 tablet into ½ cup cold tap water until dissolved. Once the milk is 90ºF, add the dissolved Junket Rennet mixture. Mix the milk and Rennet together for about 10-20 seconds and then take the mixture off of the heat. The next step is to…

Prohibition outlawed the utilization, assembling, offering, and transportation of Liquor (Schultz, 2013). The United States added the eighteenth amendment to the constitution denying this action in 1919. The law took effect on the grounds that alcohol caused social and physical issues that were less than favorable for the one that was partaking and their families. A few of the conditions that were discussed while this new system was being created consisted of broken families, violations, loss…
