Physically, the unknown compound was composed of white, grainy, crystal-like structures. The unknown was also odorless. From these observations, various physical and chemical testing was performed to determine properties of the unidentified compound. A series of solubility tests were performed, as shown in Table 2, and revealed that the unknown compound was soluble in water, but not in Acetone or Toluene. Because the compound dissolved in water, it is known that the compound is either polar or ionic3

Unknown compounds verification Introduction: In Project 3 we are going to test an unknown compound and there are several different ways that can help us to identify the Unknown substance. And there is some pre-lab information that found in the internet. By Experiment 3: Identification of a Substance by Physical Properties “Every substance has a unique set of properties that allow us to differentiate one from another. These properties can be classified as either physical properties or chemical
Final Essay Questions Pure substances are either in the form of compounds or elements. A compound can be decomposed by ordinary chemical means and are made up of two or more elements. An example of a compound is water, which is H2O. Elements, on the other hand, are pure substances that cannot be broken down because they are in their purest form and an example of this would be gold, which is Au. In contrast, mixtures can be made up of homogenous or heterogeneous mixtures that can be separated. In

In order to find this hydrated compound, it is necessary to use the law of multiple proportions. In other word, finding the appropriate variables values to this compound (CxCly*zH2O). Additionally, two major steps are required to proceed the experiment. The first consists to heat a sample to liberate the water hydration, and
First, two grams on an unknown white compound were given. The possible compounds the known could be were CaCO3, KNO3, NH4Cl, CaCl2, K2SO4, (NH4)2SO2, Ca(NO3)2, NaC2H2O2, K2CO3, MgCl2, Na2CO3, 0.1 M AgNO3, MgSO4, NaCl, 0.2 M BaCl2, KCl, NaSO4, Mg(s), HCl, HNO3, NaOH, HC2H3O2, H2SO4, and KOH. The solubility test required using a scale to measure .575 of our unknown white compound. The unknown compound was measured in a 100 mL beaker. Next, a 100 mL graduated cylinder was used to measure 60 mL of distilled
A new oral pharmaceutical drug for type- two diabetes had been approved for clinical use, it was called Compound 17392. Marketing companies instantly wanted to have prescribers adopt and sell the product and researchers wanted to further investigate previous reports of liver toxicity in patients. Now since paying patients to try new pharmaceutical drugs was an issue due to it appearing to interfere with clinical judgement and upholding the duty to do what is best for the patient, a new idea of
During the circle time, Caydence sing a song along with her peers, ABC Song, “A,B, C, D, E, F G, H, I, J, K,….O,P, Q, …., my A, B, C, ne…..sing wit.. me.” Next, the teacher uses the cards of shapes. When the teacher shows cards of shapes and everyone says the names of shapes, Caydence says, “Circle, star, square....”: she does not say all names of shapes. Then the teacher shows the cards of colors, Caydence says, “Red, blue, yellow, green, orange, pink, purple…” as the teacher shows the cards:
Analyses - Let America Be America Again Langston Hughes uses a varied meter in “Let America Be America Again”. In the first line and title of his poem he starts with the first syllable [let] stressed, followed by a unstressed syllable [a]. This trochaic dimeter is used just for the first four syllables, following a iambic tetrameter starting with [ca] unstressed and [be] stressed. The second line starts with a trochee, but this time with eight syllables, therefore a tetrameter. The last syllable
It is “foolish men” who fail to see that acute insightfulness is a vehicle for precise thinking. Nevertheless, the speaker shuns drawing conclusions about whether the creation of art contributes to, or ease madness, by attributing her speculations to theories others have proposed. In the final lines of the poem, however, she endorses the decision to explore dark corners of the mind and expand the limitations of the self by drawing attention to the affective dimension of the work, the beneficent effect
In this lab, three unknown compounds were separated from a mixture and identified by melting point. Unknown mixture #124 has components of acid, base and neutral compound. The compounds were identified by melting point and matched up with the known melting points from a given list. In order to identify the compound it was important to separate by dissolving the mixture in an organic solvent which was not soluble in water, and then extracting the solution first with HCl, and then dilute sodium hydroxide
experiment was to identify an unknown compound by running various tests to determine the qualitative solubility, conductivity, and pH value of the compound. Tests were also performed for the presence of specific cations and anions in the compound. The second goal was to discover the reactivity of the unknown compound by reacting it with different types of substances. The third goal of this project was to calculate the quantitative solubility of the unknown compound in water. The last goal was to determine
Introduction and Purpose In this experiment, we completed a series of chemical reactions to demonstrate the properties of pure copper and compounds derived from copper. A sample of 0.04 grams of copper was put in a test tube to undergo five different chemical reactions including decomposition, single-displacement and double-displacement. The first reaction consists of adding 40 drops of nitric acid to the copper sample. In second reaction, 6 moles of NaOH was added to the copper nitrate to produce
The Red Wheelbarrow The Red Wheelbarrow is a poem written by an American poet called William Carlos Williams. Initially, the poem was published without a title, and the poem is in form of verse form. Williams in his writing constructs an image within the readers mind. The author uses simple words to construct a poem that is basically based on imagery philosophy. Williams’s poem is all about a red wheelbarrow that is painted in the readers mind in order to create a flamboyant picture. The Red Wheelbarrow
The poem “A Fit of Rhyme against Rhyme” is a response to Samuel Daniel’s prose essay A Defence of Rhyme, in which Daniel describes rhyme as an “antidote to endless motion, to confusion, to mere sensation, to the sway of the passions” (Reading the Early Modern Passions: Essays in the Cultural History of Emotion, 146); while Jonson’s response describes rhyme as a “rack of finest wits, that expresseth but by fits true conceit” (1072, 1-3). Jonson’s poem ironically uses rhyme to ridicule rhyme in a
In science, an ionic compound is a concoction compound made out of particles held together by electrostatic powers named ionic holding. The compound is unbiased by and large, yet comprises of emphatically charged particles called cations and adversely charged particles called anions. These can be basic particles, for example, the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic species, for example, the ammonium (NH+ 4) and carbonate (CO2− 3) particles in ammonium carbonate. Singular
In this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with different polarities are used to dissolve and separate different solute components, so they form two distinct liquid layers. In this experiment, ethyl acetate, an organic solvent, and an aqueous solution, were used as the two immiscible solvents. The extraction solvent must be capable of dissolving one of the mixture components, without irreversibly
objective of the Unknown White Compound experiment was to investigate the compound’s physical and chemical properties to correctly identify and then synthesize the compound. The first step was to test the compounds solubility and create a solution with distilled water. Next, a pH test was conducted by testing the unknown compound using pH paper. Following, the flame test was used to determine the cation and the ion test was used to determine the anion, which concluded the compound to mostly be potassium
