Copper in Silver Nitrate Lab: Making Silver Sabrina Kate S. Carranza – Chemistry Hour 6 I. Purpose: The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors. II. Hypothesis: /3 -If the copper metal is submerged in the silver nitrate solution

Teaghan Hignett March 15, 2015 Mr. Cho SCH3U Metal Reactivity Series Lab 2015 Question: What is the relative reactivity of aluminum, potassium, copper, iron and hydrogen? Introduction: This lab will introduce several key concepts surrounding metal reactivity as well as electronegativity and periodic trends on the periodic table. Electronegativity by definition is a measure of the tendency of an atom to attract a bonding pair of electrons. In a bond between atoms in a molecule, the atom that

experiment gather a lime, an orange, an apple, a zinc nail and a copper nail to model the essential parts of a battery. The zinc nail represents the negative charge while the copper nail imitates a positive charge. To measure this energy created in the fruit an analog multimeter was used. The procedure used is below. Collect the materials required for the experiment. Lay out a lime, a zinc nail, and a copper nail. Push the

Agriculture commodities include wheat, rice, pulses, cereals, edible oils, ground nut etc. Non- agriculture commodities includes crude oil, non ferrous metals like gold, silver, nickel, copper etc. My basic study of bullion and specifically of gold & silver led me to the fact that though India is the largest consumer of gold & silver. India largely has unorganized gold market. The government policies regarding the same have also

a semiconductor. Photoluminescence intensity may be directly correlated with the defect density in a fluorescent material. However, the CuO has low emission efficiency (CuO is not a fluorescent material) so there is a lack of luminescence data for copper oxide. Furthermore, recent theoretical calculations indicate that although Cu vacancies are the most stable defects in CuO, they do not introduce new states within the

2H2O(l) Before Copper is a reddish brown powdery and lustrous substance. HNO3(aq) is colorless and transparent liquid. During Adding HNO3(aq) made the solid copper change color and state of matter. The solid brown copper turned into a green liquid. Bubbles formed at the surface of the solution and a yellow-brown gas was released. The beaker became warmer and the temperature of the solution increased. After The substance turned into a clear and non-viscous blue liquid as the copper dissolved completely

We observed the combination reaction between zinc and iodine in a balanced chemical equation to help us understand the troubles and process of getting a pure product (zinc iodide). Then we performed the decomposition of zinc iodide by electrolysis. After observing the properties of the substances we can then confirm whether or not zinc and iodine are present in the original compound. Overall, we set out to prove that the Law of Conservation of Mass is held true in a balanced reaction. We began

plumbing was found in Mesopotamia it is estimated to have been made around 3000 BC. The pipes were made from clay mixed with short lengths of straw. This was the first type of pipe to be used to transport water from different places. Both brass and copper pipes have been found in Egypt believed to have been constructed close to 2500 BC. The Romans used lead pipes, extensive use of lead pipe by joining sheets of lead into piping to carry their water supply and waste. Two millennia ago the ancient Romans

In Plato’s The Republic, Plato uses a central story, the myth of the three metals, to illustrate his ideas as a whole. The myth of the three metals is based off of the story that Mother Nature invented all human beings and created these human beings by utilizing different metals. The three metals utilized were gold, silver, iron or bronze. From these metals, each person was born into the role they would presume in society. Gold represents the guardians, who are governed by reason, making them

CHAPTER TWO LITERATURE REVIEW 2.1 Water pollution FAO (1992) noted that the adulteration of water supplies from both natural and anthropogenic sources has impacted on the health and economic status of populations. Human activities contribute to pollutants such as heavy metals, pesticides and herbicides into aquatic ecosystems. These anthropogenic activities continuously increase the amounts in the environment. According to Malik et al. (2010), heavy metal pollution is burgeoning at an frightening
