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

Reactions of Copper Data: Part I: Preparing a solution of copper (II) nitrate Initial mass of copper wire: .520g Mass of copper wire after vigorously scouring: .518g Observations of Copper (II) ribbon mixed with HNO3: Solution turned green. Thick brown gas formed. Copper (II) bubbled vigorously. Cu (II) dissolved‚ solution appeared green/blue. After the addition of H2O a blue crusty precipitate formed. Part II: Synthesis of solid copper (II) hydroxide Observations of Copper (II) nitrate

Copper vs. fiber Everyone building a network must face this question at some point: fiber or copper wiring? For a usual home network or even a big office either one will suffice but what is the best option for you or your company. You have to take cost‚ distance of cabling‚ and bandwidth and speed into consideration when making this choice. Copper: a traditional copper wiring for a network certainly seems much cheaper on the surface. Copper wiring itself is dirt cheap at least comparatively

and Processing Raw data Table of raw data Qualitative observation: At the start of the experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat distribution‚ which

descending into the mine to go to work. Little do most families know‚ they might not see the important men in their life again. The Cherry Coal Mine Disaster is greatly known as one of the worst mine disasters in America taking the lives of over 200 people and leaving many families devastated. As a result‚ mine safety regulations were regarded. Being a miner was a very common occupation for men back in the 1900’s‚ over 500 men and boys went to work at the Cherry Coal Mine‚ located in Cherry‚ Illinois
