In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2

Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

chemical element copper‚ with Atomic Number 29‚ has been extensively used for thousands of years because of several primary properties that have dictated its use throughout history. Among them we can count durability‚ strength and‚ as a semi-noble metal‚ good resistance to corrosion. With a hardness of 3 on the Mohs scale‚ pure copper is relatively soft and malleable‚ which makes it an easy metal to work with. Analyses of artefacts from lithic civilizations have shown that native copper had not only

Cosc 3215 The Impact of Monitoring Employment I wanted to discuss the technology used to monitor employees. Whether it be at the computer/workstation or on the cameras set around the workplace. More and more companies and corporations are implementing monitoring software such as Spector‚ Sonar‚ Spytech‚ and iSafe. All used in order to keep track of employees on what they are looking at‚ what they are working on‚ and how much time they do it. You start to wonder when it becomes too much. Or when

Gray 1 John Steinbeck’s novel Of Mice and Men deals with many different themes. Revolving these themes are characters overcoming issues and conflicts in their lives. One of the themes that have created the biggest impact on the characters in the novel is loneliness. Loneliness occurres in every character’s life‚ and impacts it drastically. Ronald Anthony says “When we truly realize that we are alone is when we need others the most.” This quotation means a person never fully realizes the importance

Furthermore‚ the speaker uses a proud tone in the example‚ “I was so proud of myself for stopping for that red light.” Thus‚ stating that he was proud that he did do right and realized that he didn’t think twice about it. Pride is one of mankind’s’ best attributes and sometimes the worst. In this case‚ pride is granting the speaker a chance to express his gratitude for humanity’s uncanny ability to surprise itself and show we are naturally striving for greatness

Copper is reddish with a bright metallic lustre It is malleable‚ ductile‚ and a good conductor of heat and electricity (second only to silver in electrical conductivity) Its alloys‚ brass and bronze‚ are very important Has various oxidation states: 0 in elemental copper‚ +1‚ and +2 which is observable in corroded

mass of copper wire was 1.250g but the recovered copper was only 0.120 subtracting the mass of the recovered copper with beaker from the tare beaker mass. So the percentage yield resulted only to 9.6% it is very little‚ and it may be due to many possible sources from doing the steps. Adding too much or too little of a compound to the copper solution‚or the loss of copper during transport or by being left on the stirring rod. Another situation which was a source of error is when the copper solution
