Sodium compounds

What is Sodium cyanide? Sodium Cyanide is an inorganic Compound, it has a formula NaCN. Cyanide actually has a high affinity for metals which can lead to a high toxicity of the salt. Sodium Cyanide has a boiling point of 2,725°F (1,496°C) and it also has a melting point of 1,047°F (563.7°C). A common name for sodium Cyanide is sodium salt of hydrocyanic acid. Cyanide has an appearance of while crystalline or granular powder. This toxin releases a hydrogen cyanide gas which is highly toxic that interferes with the body’s ability to use oxygen. If you come into contact with sodium cyanide can be rapidly fatal, it can have a whole-body effect especially affecting the organ system that are most sensitive to low oxygen levels. Some…

hydroxide, then not enough iron to produce a substantial amount of complex to create a noticeable color change. Consequently, the maximum absorbance of the iron (III)-thiocyanate depends on the pH and duration. Anion Effects: Different salts were added to determine if solvent composition has an effect on the maximum absorbance. The mixture between the complex and sodium fluoride had a significant reduction in the color of the complex. This could result from iron (III) binding to the fluoride…

medley. The phonological medley equips students with the ability to use two syllable compound words. This lesson model assists students in becoming familiar with blending, deletion and segmentation. It is presented on chapter five titled Phonological Awareness and the lesson is on page 132. 2. Why did the approach appeal to you? What did you like about it? Why would you recommend it to other teachers? The phonological medley is a highly interactive lesson that gives students the opportunity…

LIN 3010 Word Formation Processes - Compounding o Obamacare: 2013 noun: term for the Affordable Care Act that does not have the same meaning as when the terms are broken. o Humblebrag: 2011 verb: when the two words are combined, the term’s meaning changes to an expression of false humility, especially be celebrities on Twitter. o Lumbersexual: 2014 noun: when the morphemes are stick together, the term means a fashionable rugged man who adopts the stereotypical dress and facial hair of a…

In the compound “slaughter/fall” (125) the second element can not only mean “a fall in battle” but also “feast” or “fill.” So there is sometimes doubt about accuracy in translating. In the Finnsburh Episode the Danes are fighting the Frisians, and the poet says: “So they offered terms [of peace]” (1085). The “they” (hig) is indefinete and could refer to either warring party – intentional ambiguity; there is debate among scholars as to the proper referent of “they.” In line 1149 a sea-journey is…

By creating guided reading lesson plans, I was able to help my students develop their phonemic awareness by incorporating word work activities that involved working with multisyllabic words. Therefore, the students were able to understand that words and syllables are made up of sequence of sounds. The word work activity in the informative text got the students to increase their vocabulary and spelling knowledge by working with compound words. The word work activities in both lessons also…

1. Broken People - message: Someone is injured and they need a doctor. - shining moment: repetition of “I’m a doctor”, looks like a robot. And the patient said, “ok, I’m healed.” LOL 2. Group 2 - message: The transformation from the high school life to the marriage of a high school couple, and the teacher is a witness of their love story. - shining moment: distracted class looks so realistic (being late, playing phone, passing notes...) 3. Girl Scouts - message: writing a dramatic story…

Sodium polyacrylate is a polymer with a unique structure, that chemists are leveraging in a variety of lucrative industrial applications. Sodium polyacrylate possesses a unique chemical property: the ability to absorb incredible amounts of water. It can absorb 300 to 800 times its weight in water (Superabsorbent Polymers). Industrial chemists have taken advantage of the polymer’s special function, and have incorporated it into dozens of different products. In fact, the industry behind…

liquid form. This is a physical change because its actual material that it consisted didn’t change, meaning, it’s still sugar, but in liquid form. Mixing solid copper sulphate with water is a physical change because a new substance was never formed and the copper sulphate is still copper sulphate, but in a different state. Plus the fact that the final product turned into a mixture (solution), which is another sign of a physical change. The changes I examined that were chemical in my experiment…

This discovery took place in England; the year of 1807. It was founded from the english word “potash” and the arabic word “qali.” The word “qali” means alkali which is potassium's family on the periodic table. Potassium then was recognized as an element when potassium carbonate was mixed with animal fat to make soap. Therefore, it was made by extracting wood ash with water. The name “potash” was derived for potassium salts. The isolation of the element was done through electrolysis of (KOH). The…
