funnel. Next, 40 ml of 0.1M of sodium hydroxide, NaOH solution was measured and poured into a clean 100 ml beaker. The sodium hydroxide solution was then added into the separating funnel that has the organic extract from the earlier procedure. The separating funnel is then shook gently for 2 minutes in order to mix the contents together. Then, the aqueous extract solution was poured into a 250 ml volumetric flask. Next, make up to the volume with 0.1 M sodium hydroxide…

Discussion of the Results and the Scientific Explanation The purpose of this experiment was to identify an unknown compound and discover its properties by devising experimental designs that enable for its identification (Cooper, 2009). Fifteen possible compounds were given, and a series of qualitative tests were used to eliminate the different possibilities and identify the specific unknown compound. These tests included a solubility test, which determines whether the compound is soluble in…

Analysis of Galvanized Nails, Quality Control, and Green Chemistry Introduction: In this lab, we handled acidic chemicals that needed to be disposed of upon completion of the lab. We disposed of these chemicals according to safety policies and green chemistry policies. Green Chemistry is the practice of chemistry in an environmentally safe way to prevent pollution. We used green chemistry to minimize the amount of waste we were to be creating. We ended up creating waste from degalvanizing…

examples of the side reactions that occur during oligonucleotide synthesis are given below. Tri-O-acetyluridine (S.1) reacts with MSNT to produce the triazolo derivative S.2 (Figure 2.1.2; Reese and Ubasawa, 1980). During deprotection with ammonium hydroxide, S.2 gives cytidine (S.3). Interestingly, during deprotection with either the tetramethylguanidinium…

The procedure for Lab 5 contained four parts. For Part A, a clean, dry 100 mL beaker was obtained and filled with 60 mL of distilled water. Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry,…

the fast-food industry leads to the lots of chronic diseases, hormonal disruptions, and heart attacks that can cost a life. To prevent the obesity, the government should improve the law for the fast-food industry and prohibit the use of ammonium hydroxide and other harmful food additives. The government must oblige the fast-food industry to indicate on the product labels all information about the ingredients and methods of producing the food. Also, the age restriction of eating fast food can…

The test tubes that contained bases were Sodium hydroxide, substance 3 and substance 4 the substances that had a neutral pH level were substance 1 and substance 5 the test tubes that acidic liquid were Hydrochloric acid, substance 2 and substance 4. The way this was determined was by comparing it to a red…

the beaker Do not take out the cubes for the following 10 minutes. In the meanwhile, observe the temperature Once the 10 minute has been reached, take out the 4 cubes using a spoon and place them on the petri dish After ensuring that no sodium hydroxide has been left on the cubes, cut all 4 of them in half and keep record of the measurements Data Collection In order to keep track of all the collected data, the following table will be utilized. Please note that even though the materials and…

Biodiesel production is usually expressed through the process of trans-esterification reaction. Recently, homogeneous catalysts are broadly preferred for biodiesel production in eminent scale operation. Still, they are toxic, highly flammable and corrosive in nature [1]. Boey et al. analysed the purpose of the waste cockle shell from palm olein oil in biodiesel production of Anadara granosa. At 900 °C the waste shell was calcined for 2 h that mainly compiled of 71% of Ca to develop an active…

Factory farming is a cruel, unsanitary, and abusive practice that has many harmful affects not only the animals confined in slaughterhouses, but also on unsuspecting consumers. By creating tighter government regulations regarding how the animals are raised and how the meat is treated, we could avoid all of the potentially deadly side effects linked to factory farming. While mass production of poultry and beef has done wonders for restaurant supply and company profit, the measures taken to…
