Prac 18 – Reaction Rate of Notongooglenium – Angus Dally Research Question: How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)? Aim The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its…

54) The following graph shows three different stresses on the reaction. For each stress, numbered 1, 2, and 3 on the graph, identify the stress that has been applied to the system and using Le Chateliers principle, explain why the graph changes the way it does. 1) At the point marked #1, all three concentrations gradually increase, showing that heat is added. The addition of heat puts stress on the system, so the equilibrium shifts to the right to partially undo “stress” and produce more…

called the Grignard Reaction lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of the Grignard Reaction lab was to…

The expression "SN1" is the abbreviation of "unimolecular nucleophilic substitution reaction", one of the most common reactions in organic chemistry. As a fundamental reaction type, the mechanism of SN1 reaction has long been clear to the researchers, and the rate of the reaction concluded from the mechanism is quite simple. According to the mechanism, the rate of an "ideal" SN1 reaction is only proportional to the concentration of the substrate, which can be expressed as the following formula:…

A. i) The rate of a reaction is the change of a substance’s concentration per units of time. The reaction rate of an experiment is dependent on many things including concentration, presence of a catalyst, and, most importantly, temperature. Temperature and reaction rate are directly correlated, which means that as one increases, so does the other. It is a general approximation that the rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature…

There are so many chemical reactions and it is important to classify a chemical reaction to understand the reaction and predict the products. In this lesson, we will discuss the definition and go over examples of a combination reaction. !!!What is a Combination Reaction? Putting furniture together, combining ingredients to make something delicious – these things can be fun activities and we look forward to the results. Each individual component is not very exciting by itself. However, if we…

Solventless Reactions: The Aldol Reaction CH204-01 Fadwa Mekkaoui Introduction: An aldol reaction is the formation of a new carbon-carbon bond by the addition of a nucleophile to an electron deficient carbon. The reaction is favorable in Green Chemistry. It demonstrates green principles such as using no solvent and having a high atom economy. In the lab a mixed aldol reaction was performed to synthesize an unsaturated ketone from and aldehyde and ketone. By using an aldehyde, that doesn’t…

Chemical reactions are a process that involves, rearranging the molecular structure of substances to create new ones. There are 3 types of chemical reactions, firstly there's synthesis, (e.g. 2Na + Cl2 → 2NaCl); then, the other type of reaction is decomposition (CaCO3 → CaO + CO2); and finally there is combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types of reactions,…

This essay will be talking about Reactions and how it affects substances.A reaction is a chemical process in which two or more substances act on each other and are changed into different substances, or one substance changes into other substances.There are eight reactions we will be talking about and they are Decomposition,Combustion,Acid and Base,Synthesis,Single-replacement,Double-replacement,Precipitation,and Redox.In the world today there are many reactions out their but we will only be…

The purpose of the experiment is to perform a series of chemical reactions involving copper. The goal is then to perform precipitation, acid-base, decomposition, and redox reactions using the copper cycle. The mass of the copper was then analyzed using the percent recovery formula. Reaction 1: The Formation of Cu(NO3)2: Reaction 1 of the experiment involved performing a redox reaction to create Cu(NO3)2. Immediately after HNO3 was added to the copper wire (Cu), the brown NO2 gas was emitted from…
