Our hypothesis was partially correct, the property changing substances did have the weakest coherency with the lowest drop counts of 23(carbonated), and 14(soap), and pure water did have the strongest bond. What we also found was the the salt also dampened the liquid’s ability to hold onto a penny in large volumes, as all the different salts had a drop average of 24(28x2 & 16), five less than Tap water’s drop count (30). This led us to conclude that pure water has the strongest bond and that all foreign materials weaken the coherency of water. This evidence has led me to believe that similar substances are attracted and are more coherent towards themselves, in this case the water pieces get separated and generally less connected on a really small level due to the obstruction of foreign objects, this is why the different salts perform better than the huge air bubbles or the slippery properties of soap since the latter is more obstructive and the former dissolves with the water and blocks less. When studying a few other groups’ conclusions and data we did indeed find differences: some groups had differing data where a solution had better coherence than water itself which led to differing conclusions.
Covalent bonding - Covalent bonding is when two atoms share electrons this can only occur between two non-metals. They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons
Because the compound dissolved in water, it is known that the compound is either polar or ionic3. Water is a polar substance, which maximizes its interactions with other polar molecules. Ionic substances also interact with and dissolve in water, because they can be considered an “extreme” case of polarity in which electrostatic forces hold atoms together. The interaction between water and the unknown compound can be described as “dissociation.” When a molecule is dissociated in a polar solvent, the anion of the molecule bonds with the solvent’s cation and vice versa4.
Conclusions The experiment contained six ionic 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.
2. In the contest of these two reactions, which is the better nucleophile, chloride ion or bromide ion? Try to explain this. Bromine is a better nucleophile.
It’s mainly found in chloride minerals, which is also known as sodium chloride or commonly known as salt.
This experiment aims to identify the pigments in spinach using column chromatography. The two categories of pigments which exist in spinach are carotenoids and chlorophylls. β-Carotene is non-polar and is a series of repeated isoprene units, see Figure 1 for structure. It varies from α-Carotene by the double bond on the left carbon ring which is shifted over to the left by one set of carbons in α.
In order to understand water, Stillinger argues that hydrogen bonding is sufficient to point to start from. In fact, hydrogen bonding is a result of an electrostatic attraction between electronegative atoms. Hydrogen bonds are directional bind. This means that the hydrogen and the oxygen in the water that create the hydrogen bond are directed to each other. The strength of the hydrogen bond is approximately 5 kilocalories per mole.
Along with adding flavor to food, salt is essential for human life. Foods that would have bitter and muddy flavors without salt become rich and flavorful when it is added. Sea salt and table salt are two common forms of salt that will be familiar to most experienced cooks. How similar are they? Do they taste the same?
There are two main types of salt- the ubiquitous refined salt and unrefined salt. Refined table salt is toxic to the body and triggers many degenerative diseases including hypertension, diabetes, stroke,
Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
Proteins are made up of peptide bonds holding amino acids together to perform biological functions like enzymes, antibodies, for transport and structure (Asmus, 2007). Lastly, nucleic acids

. SUPER HYDROPHOBICITY Soumya Ranjan Sahoo (711CH1025) NIT, Rourkela Abstract: Superhydrophobicity as a sensation has turned into an increasing focus of research and technological movement, where its key viewpoints span surface chemistry, chemical physics, and cellular biology. Hydrophobic particles have a tendency to be non-polar and, accordingly, incline toward other neutral molecule and non-polar solvents. Hydrophobic atoms in water frequently bunch together, shaping micelles.
INTRODUCTION Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth 's streams, lakes, and oceans, and the fluids of most living organisms. Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world.
