Not all colourss are the consequence of minus and add-on of visible radiation. Some colourss like the blue sky consequence from the selective sprinkling of the colourss of visible radiation by atoms in the ambiance. The colour scattered by the atoms depends on the size of the atoms themselves. BLUE SKYViolet is scattered more than…

Aims: I aim to find out the order of reaction with respect to [H2O2] and [2I-]. I aim to find out the activation enthalpy of the reaction by finding the rate of reaction at different temperatures using the Arrhenius Equation. The experiment will go as follows: Into a conical flask put 15cm3 of distilled water…

To understand the general process, reaction and limitations of Friedel-Crafts Alkylation in regards to Dimethoxybenzene. To apply the reaction of Friedel-Crafts Alkylation to dimethoxybenzene. Chemical Index: Chemical Structure Molecular Weight Melting Point Boiling Point Acetic Acid Procedure Measure 120 mg of 1,4-dimethoxybenzene, 0.4 mL acetic acid, and 0.2 mL t-butyl alcohol In a 10X100 mm…

The sample needed to return to the oven for a second heating to insure that all of the water was heated off of the sample. If the mass difference between the first and second heating was greater than 0. 005g, the sample would have been needed to be heated a third time because all of…

Chemistry has a noteworthy influence on our everyday lives, even if we are not conscious of it. It is present in different areas of our daily routines and engagements, ranging from the food we consume to the items we utilize. By comprehending the fundamentals of chemistry, we can make well-informed choices and acknowledge its deep-seated…

Density is defined by its mass per unit volume, and is most often written in mathematical terms as; d = m / v Mass is usually given in grams, g, and volume is given in cubic centimeters, g/cm3, or, grams per milliliter, g/mL. Density is not a property that depends upon the amount of substance…

In this study I will be giving a history of chemical warfare. I will besides be demoing a chart that includes the Agent, and many other utile information about nervus gas agents which are the chief point for chemical warfare. This study will besides include the effects of nervus gas on the human organic structure….

Crystal structure Zinc oxide crystallizes in three forms: hexagonal wurtzite, cubic zincblende, and the rarely observed cubic rocksalt). The wurtzite structure is most stable at ambient conditions and thus most common. The zincblende form can be stabilized by growing ZnO on substrates with cubic lattice structure. In both cases, the zinc and oxide centers are…

Chemists believe that for compounds, atoms, or ions to react successfully, the particles must collide together. This is the basis for a scientific theory known simply as the collision theory This theory is based on the idea that the rate of a reaction is determined by the number of successful collisions that occur over a…

Acetophenetidin can be synthesized using two methods: Williamson ether synthesis and amide synthesis. Working in pairs, we were able to successfully complete both synthesis routes. The ultimate goal is to verify that the two individuals’ methods yield a similar product. Initially, the Synthesis reaction started by eliminating the colored impurities from the p-phenetidine. This was…
