Sodium compounds Essays

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

aqueous compounds that reacted and formed new products. The reactants were barium chloride, potassium nitrate, silver nitrate, sodium carbonate, calcium sulfate, and sodium phosphate. In Station 1, barium chloride and potassium nitrate did not react. Barium chloride and silver nitrate created aqueous barium nitrate and the precipitate silver chloride. In Station 2, potassium nitrate and silver nitrate did not react. Potassium nitrate and calcium sulfate did not react as well. In Station 3, sodium carbonate

materials to solve for a certain solution of a compound. To figure out the aqueous solution of sodium phosphate which is Na3PO4 12H2O, you need to figure out the total mass of sodium phosphate dodecahydrate in 1 mole of 1000 mL. In the compound sodium phosphate, there are 3 sodium atoms, 1 phosphorus atom, and 4 oxygen atoms. Since each atom has a certain atomic weight, you multiply the atomic weight by the total number of atoms for that specific atoms. So sodium would be a total of 68.97 grams, phosphorus

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

reactants and products is as follows. One mole of Ammonium dichromate will give rise to one mole of 1 mole of Chromium (III) oxide and 1 mole of Nitrogen gas and 4 moles of Water is gaseous phase. To convert these into formula units, 1 mole of any compound will equal 6.022X1023. So based on this, 1 mole of Ammonium dichromate is 6.022X1023 formula units. 1 mole of Chromium (III) oxide is 6.022X1023

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

Carolyn Zheng Honor Chemistry Mrs. Marino May 1, 2023 Thermal Decomposition of Sodium Bicarbonate Introduction: In this experiment, heat is added to a compound known as sodium bicarbonate, or in a chemical sense, NaHCO3. This compound is also known as baking soda in a domestic setting and has several uses due to its chemical nature. This lab tests the thermal decomposition of this compound by heating this compound under a Bunsen burner. There are four possible equations that will theoretically

reaction is when two or more reactants all “synthesize” or join together to form a new product (Kotz, 2017). Another chemical reaction type is decomposition reaction. A decomposition reaction occurs two reactants break down into two or more simpler compounds or elements. (Study.com, 2018). The third chemical reaction type is a combustion reaction. Combustion reactions occur when a hydrocarbon reacts with an oxygen

between two compounds. Moles are also involved in chemical reactions. The task is to determine how varying mole ratios of the reactants can affect the amount that is produced. Why does mixing reactants in different mole ratios affect the amount of the product and the amount of each reactant that is left over? Method:

the solubility of a substance by the change in temperature, pressure, etc. Precipitants are most likely to form in an aqueous double displacement reaction with occurs with the ions of two compounds switching places or an aqueous single displacement reaction, where a single ion will replace an ion in a compound. Whether or not a reaction occurs can be based on the

Lab 27. Stoichiometry and Chemical Reactions Report In our lab we were asked Which Balanced Chemical Equation Best Represents the Thermal Decomposition of Sodium Bicarbonate. Sodium Bicarbonate is a chemical compound with the formula NaHCO3, also known as baking soda. In the process to answer our guiding question we have to determine how atoms are rearranged during a chemical reaction. That is where stoichiometry comes along, which is the quantitative relationships or ratios between two or more

OBJECTIVE The objective was to determine the relationship between the reactants calcium chloride and sodium iodate their product calcium iodate. INTRODUCTION Experiment six was about the relationship between reactants and products. In this experiment the relationship of calcium chloride and sodium iodate in a reaction that produces calcium iodate. The calcium chloride and the sodium iodate undergo a precipitation reaction to produce calcium iodate. The goal is desirable for gaining understanding

techniques such as recrystallization, extraction, melting point, and acid-base reactions. From this, the group to which these two compounds belong to had to be determined. These groups are: Carboxylic Acids, phenols, and neutrals. By determining the melting points of the two unknown compounds, these values were compared to the values of melting points in the chart and the proper compound was selected. For the case of this experiment, the unknown mixture contained, 4-methylbenzoic acid. The neutral was not

The Element Potassium The element Potassium was discovered in 1807 by a chemist named Humphry Davy. Potassium was named after the English word “potash”, originally meaning an alkali extracted with water in a pot of burned wood and ashes of plants. Metallic potassium was first isolated by Humphry in 1807 through the electrolysis of molten caustic potash in which potassium was the first isolated metal. The symbol “K” comes from the Latin word meaning kalium and this element is not found in nature

Experimental Procedure Identifying the Unknown We performed three tests on our compound to definitively identify it. First we combined 5 g of our unknown compound with 10 mL of distilled water and measured the pH change in the water to test its solubility. Then, to try to identify the cation present in our compound and narrow down the possibilities, we held a sample over a flame and watched for color change. We performed an acid test where we applied a few drops of HCl and watched for a bubbling

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
