Chemical bond

lewis structures for compounds are a great way of visualizing how the elements bond together. To draw a lewis structure, first determine the number of valence electrons. Valence electrons are the number of electrons in an element’s outer most shell. After finding the number of valence electrons, you are…

metal resulting from reactions with chemicals in its environment. The oxygen oxidizes with the metal, and the sodium help speed up the corrosion process. The presence of oxygen and electrolytes (Sodium – Na) in sample number 2 make it more…

valued customers. It has been ranked as AAA/ A1+ by PACRA, and won an award for the Best Bank in Pakistan by “The Asset Triple A” organization . Some of the product offerings SCB provides its customer in the debt instruments are Pakistan Investment Bonds (PIBs), treasury bills, and Ijarah Sukuks. • PIBS: these are long term instruments that have semi-annual coupon payments, and have maturity dates of up to 10 years, and their auction schedules are quarterly announced by SBP. • Treasury Bills:…

fewer places for interaction, so decreasing the amount of energy required to break the intermolecular forces of attraction. 2-hexanone has the lowest point boiling point, as it much more branched and the third carbon has a functional group (double bond O), leading a high compacted molecule. Pentanol and hexanol molecules has the least amount of branching out of the four compounds above in the graph, and as such has the highest boiling…

According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…

The unknown compound we received consisted of white crystal-like particles and was a solid at room temperature. During the smell test, we did not receive any indication of a distinct smell, thus concluding that the compound is ionic. The solubility tests indicated that the compound was soluble in water, NaOH, and HCl and non-soluble in acetone and toluene as shown in Table 1. The compound was soluble in water indicating that the compound is either polar or ionic, but not soluble in toluene or…

Acme Products, Inc., requires a new machine to produce a part for a heat generator. Two companies have submitted bids, and you have been assigned the task of choosing one of the machines. Cash flow analysis indicates the following: Year Machine A Machine B ---- --------- --------- 0 -$1,000 -$1,000 1 0 417…

These properties are high melting points, are brittle, don’t conduct electricity as a solid, but conduct as an aqueous solution. Ionic compounds have high melting points because there are several strong bonds, a lot of heat energy is needed to break them. They also are brittle because once a force (hit) is applied to the compound, the ions with the same charges, lineup, repel, and split apart. Ionic compounds cannot conduct electricity as a solid because…

Fair Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface…

Title Determining the Empirical Formula of Magnesium Oxide Introduction Chemical formulas imply the arrangement of compounds. Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound.…
