Experiment 6 Title: Preparation of bis(acetylacetonato)copper(II) complex Objective: To synthesize the bis(acetyacetonato) copper(II) complex Theory/Background: All metal ions in solution are ’associated’ with water. The water molecules can also be weakly bonded or more strongly as a ligand to form a complex ion‚ and these can also present in solid ’hydrated’ salts of crystallization. E.g Copper(II) nitrate (Cu(NO3) 2.3H2O). A complex ion has a metal ion at its centre with a number

Moral Changes Moral is a wide word‚ containing lots of meanings and cannot be defined in one form. Morals are constantly changing especially with the overexposure of media. There has been no study up to date to prove that morals have changed in relation to media exposure‚ but the societies behavior in the past 30 years have proved that there could be a moral change. A study compared the morals of American people between years 1960 and 1980 shows that in the year 1980 ‚ 78 percent of young people

Ionic Reactions Results B - Do your results agree with your expectations from the solubility rules/table? Our results seemed to largely agree with the established solubility rules/table; however‚ a few reactions with the commonality of being mixed with Co(NO3)2 (cobalt nitrate) [reference Row A‚ Columns 2‚ 3‚ and 4] seemed to have such a pale pink tone that it was difficult to decide whether that could have been a precipitate or the lighting in the area where the experiment took place.

Lab #5 Chemical Reactions & Balancing Equations Objectives Observe and classify several chemical and physical changes. Give evidence for the occurrence of a chemical reaction. Write a balanced equation for a chemical reaction. Identify a reaction as a combination‚ decomposition‚ replacement‚ or combustion reaction. Background Physical properties can be observed without changing the chemical composition of the substance. Common physical properties that can be measured without changing the chemical

We will also describe what is occurring with the molecules on a molecular level. Lastly we will explain what chemical bonds are formed and or broken when lemon juice and backing soda. Observations of the Reactants When most people hear baking soda they think of the bright orange box sitting in their pantry or refrigerator soaking up the foul odors

Detecting Signs of Chemical Change REAC 399 Prepared by: Elizabeth G. Perez Date of experiment: October 3‚ 2006 Course: Chemistry 100/60 Abstract: The objective of this experiment will be to combine various substances‚ liquids and metals‚ and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical. Introduction: An elements¡¦ reaction to certain substances may be predicted by its

Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can also

Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation
