Copper is the 29th element in the periodic table‚ located more specifically at group 11‚ period 4. Because of its chemical and physical attributes‚ it is a transition metal‚ which denotes high boiling and melting points. Both a conductor of heat and electricity‚ Copper is ductile and malleable. Its symbol “Cu” derives from the Latin cuprum. Copper is also valued for its two-for-one practicality: it is a vital nutrient that has antibacterial properties. Aside from what many people generally know about

Oliver Noah Kent AP Chemistry Block 3/4 Laboratory #4: Mole Ratios I. Hypothesis: If copper wire is placed in an aqueous solution with silver nitrate‚ then silver crystals will grow on the wire surface and the solution will gradually take on the color of Copper (II) ions. The relative quantities of reactants and products in this chemical reaction can be determined by measuring the mass of copper wire consumed in the reaction and the mass of silver crystals that result. These measurements

Procedure: Safety goggles‚ gloves‚ and lab apron were put on. (Only the ones who were doing the experiment) 50mL of water was placed in the 100mL beaker and heated until boiled. And the boiled water will be used as the water bath. The lab marker was used to make 3 marks (1 cm apart). 1.0 M copper (II) nitrate

Assignment: 1 Copper vs. Fiber In this paper we will discuss two different cabling solutions (copper & fiber)‚ and in what situations you would choose one over the other. One might be better for one type of application while the other might be a better fit‚ depending on the situation. They each have their own advantages which we will discuss in the following paragraphs. The first type of cable we will talk about is copper cabling. There are three main advantages in using copper cabling: (PoE‚

Determining an enthalpy change of a displacement reaction Aim: To determine the enthalpy change for the displacement reaction between zinc powder and copper (II) sulphate solution. Zn (s) + Cu2+ (aq) → Cu2+ (s) + Zn2+ (aq) Theory: For the displacement reaction‚ an excess amount of zinc powder is added to the measured amount of aqueous copper (II) sulphate. The temperature change over a period of time has to be measured and thus‚ the enthalpy change for the reaction can be measured. The equation

are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper sulfate that can be added in the water and be dissolved will increase. Theory: The hypothesis will be proven because when temperature is increased‚ energy is released and this energy breaks the forces that held up the atoms together of a substance

carbonates of sodium and potassium are stable at the highest temperature of a Bunsen burner flame‚ whereas the carbonates of silver and copper are easily decomposed. In this experiment copper (ii) carbonate will be decomposed at a high temperature‚ forming copper (ii) oxide and carbon dioxide: CuCO3(s) arrow CuO(s) + CO2(g) You will test for the formation of copper (ii) oxide and carbon dioxide.
