The Unknown

In this experiment, identifying the acids, bases, or neutrality of the unknown substance in a specific set are used to find the actual substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver…

As the child discovers the world, she also learns several survival skills along the way. In the same manner, all the knowledge I learned from Microbiology class and laboratory sessions regarding microbial world equipped me to identify bacterial unknowns from a clinical sample. The task was to successfully separate and accurately identify two bacteria of a specimen taken from an abscess to safely and effectively treat the patient. A clinical sample # 76 was handed over by the…

straight.” At the end, Dickinson writes that the path is “almost straight.” This signifies that no one’s life is going to be perfect, and the life can still have darkness awaiting. The use of darkness is thoughout the poem. Darkenss is shown as the unknown path one has in…

additional 10 Group B offense category (Author Unknown, Jan 2013, p 6). By design, LEAs generate NIBRS data as a by-product of their respective Records Management Systems (RMS) (Author Unknown, Jan 2013, p 6). Therefore, an LEA builds its system to suit its own individual needs, including all of the information required for the administration and operation; then forwards only the data required by the NIBRS to participate in the FBI UCR Program (Author Unknown,…

Knowing the identity of microbes is essential for knowing the causative agent of a disease in order to provide patient’s effective treatment. The purpose of this lab is to identify the unknown bacteria that was given. Applying all of the techniques that have been learned in the lab will help identify and distinguish the unknown bacterium. While identifying the bacteria, it is important to examine the morphology and characteristics of the bacteria. Identifying and studying bacteria can lead to…

The fear of the unknown has driven humans to act radically for centuries. In Greek mythology, citizens feared the wrath of the gods. Fear determined and shaped the citizen’s behavior, therefore the Greeks behaved accordingly, so punishment would not be placed on them. Imperialism is “a policy of extending a country's power and influence through diplomacy or military force”. White Europeans invaded the African countryside in search of valuable materials, but disregarded the African’s humanity…

prepared via a radical mechanism. The Grignard reagent was then used to prepare a carboxylic acid from carbon dioxide, demonstrating its ability to create carbon-carbon bonds by acting as a strong nucleophile. As the R group of the Grignard reagent was unknown, molecular weight and melting point were then used to identify the resulting carboxylic acid. The molecular weight was determined using titration techniques and the melting point was measured using a Mel-Temp Apparatus. Data and Results …

The Case of the Mix-Matched Chemicals Hypothesis: By measuring the pH of the unknown and known chemicals, the types of chemicals in the unknown bottles will become known. Purpose: The purpose of this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium…

and why true motility helped microorganisms in their environment. Motility agar was used in this experiment and a needle saturated with the unknown microorganism was inserted straight into the agar. The following week it was found that there was no bacterial growth outside of the stab line in the agar which indicates the unknown as being nonmotile. The unknown microorganisms morphology and the arrangement were identified after laboratory four through simple staining. Single staining consists of…

experiment is made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is performed correctly, the actual density of water will equal the theoretical density of water. In the second section, the density of an aluminum sample will be measured and afterwards compared to the accepted density of aluminum and an unknown sample…
