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

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.

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

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

Copper vs Fiber Some advantages of Copper Cabling are Power over Ethernet this gives you the ability to power phones‚ surveillance cameras‚ Wireless Access Points‚ and many other devices right through the networking cable itself. That means that you don’t have to schedule an electrician in to run power to your surveillance cameras to power them. Another advantage is the ability to have an emergency power supply that will continue powering mission critical devices even if your electricity goes
