Question: what is the appropriate method of identifying compounds as either ionic or covalent based?

Background/Hypothesis Ionic compounds are created from the strong electrostatic bonding between ions (Brinker, and George 393). The covalent compounds have are formed by bonds that result from sharing of electrons (Mah 31).

Solubility test Conductivity test Melting point test Color and odor test Oxidation with oxygen test Steps/Procedures. Solubility test 0.25 grams of the chemical was placed in a test tube. 1 mL of water was added and stirred using a stirring rod. The addition of I mL was added until the chemical dissolved. The chemical that did not dissolve after adding 10 mL of water was recorded. The ...

Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

The cinematic medium of aesthetic expression has come to gain the strongest footing in the hierarchy of artistic works across the entire world in the present times. Stalwart filmmakers and their quintessential works have come to gain the accolades of the world’s audience as well as the scholarly film critics. Lars von Trier is surely one of the most acclaimed directors in the history of cinema. The filmmaker has left a mark on the realm of cinema with his unique style and portrayal. It is truly intriguing to note how Lars von Trier uses the cinematic techniques and ...

There can be no denial of the fact that literature is the true mirror of the society of the world. Indeed, there are innumerous examples of seminal literary works penned by various literary artists that have come to reflect the picture of the individual and the society with utmost perfection and artistic skill. As such, one can take into reckoning the short story A Good Man Is Hard to Find, by Flannery O’Connor that can very well be taken to be an exploration of the degeneration of the individual self and the moral values of life in the ...

I and my friend James wanted to find out the absorption capacity of different color pigments mixed in water, when exposed to the infra-red radiation. Our hypothesis was the dark color pigment, on being subjected to infra-red radiation, would absorb more energy and will show up in the form of difference in temperature obtained before and after the exposure. Our experiment was influenced by some of the experiences in daily life. First observation was the preference of the light color clothes in hot day, as the light color reflects the sunlight and absorbs the little, preventing the body from ...

It needs to be reckoned that literature goes on to mirror the society and the culture. Innumerable examples can be cited where the authors have delved into the socio-cultural or socio-economic factors of the world around in their texts through their creative eyes. Now, after the Second World War, the literature of the world saw the responses of the creative artist catering to the needs of the post-war era that encompassed human existence with all its surmounting effect. One can take into consideration the works of the stalwart poet, T.S. Eliot, who engaged in exploring the socio-political dynamics during ...

The recipe for Greek mussaka and good advices I received from my neighbor who originates from Greece. Mussaka is a main course dish that is prepared in all countries of the Balkan Peninsula and is considered as a national meal in every one of them. The difference is in the meat and some people, according to taste add two egg yolks in the bechamel sauce and change the bottom or both layers with potatoes. The word béchamel has a French origin and it came much later with many other words as names to the similar things, prepared in ...

Introduction The purpose of this lab was to find the amount and percentage of nickel present in an unknown compound using the "mole method." The unknown nickel compound was dissolved in water and treated with dimethylglyoxime and ammonia solutions to obtain the precipitate of known chemical composition (bis(dimethylglyoximo)nickel(II)), which then was weighed and using this data the amount and percentage of nickel in the initial compound were found. The insoluble Ni(DMG)2 complex is formed in two steps. First, the dimethylglyoxime reacts with hydroxide ion formed through the ammonia hydrolysis to produce dimethylglyoximate anion: C4H8N2O2( ...

Introduction

A consumerism culture is one where the economical environment is defined by the patterns of purchases and spending culture of the consumers. In America, it began after the Second World War, and reached its highest levels in the early 2000s (Ali, 2009). This culture encourages the acquisition of commodities as a means to achieving happiness instead of the ideals of family religion or art. Proponents of a consumer culture argue that when people are able to meet their needs and wants, they are more productive; this helps to drive the American economy and that of other nations. Opponents of consumerism argue ...
