PRE-LAB Title: Density of Metals – Shot Lab Purpose: The purpose of this lab is to find out the density of different metals using their mass and volume. If the volume and mass for the metals Nickel and Copper are found‚ then we can figure out the density. Materials: Metal shot Plastic rinse bin Electric Balances Calculator Graduated Cylinders Water Wire Gauze Weigh Boats Pre-lab Questions: 1) The volume of the water is 43.0 mL 2) The volume of the metal shot and the water is 73.0

47 and symbol Ag. It is white‚ soft‚ mallable and ductile metal slightly harder than gold. Silver is extremely flexible‚ this means that it can be converted into both flat sheets and electrical wire. This makes silver is an ideal metal for all kinds of industrial use. Silver occurs in lead‚ Zinc and copper ore deposits. Lead ore is the main source of Silver. In fact‚ 75% of the resources in the world are found in association with other metal ores. The most important mineral is argentite‚ Sulphur Sulphide

Cobalt Wedding Bands Review Cobalt wedding bands are crafted having a super strong metal that mixes an incredibly higher level of sturdiness using the vibrant reflective appearance of white gold or platinum. Using the many pros cobalt engagement rings have to give you‚ cobalt rings might even at some point exceed tungsten and titanium wedding rings. To discover if this sounds like the best metal for the wedding ring‚ and also to begin to see the benefits and drawbacks of cobalt plus how cobalt

ANALYSIS On the first part of the experiment which is the determination of specific heat of metals. The obtained value of experimental specific heat of metal of aluminum and copper are 0.2152 calg-℃ and 0.0958 cal g-℃ ‚ respectively. It is a must to work faster in performing this experiment because working in an air-conditioned room greatly affects the result of the temperature. For the temperature values‚ the final temperature of mixture should not increase more than 1 ℃ compare

Chemistry assignment Introduction: Throughout modern day society metals are constantly used‚ in fact mankind has been heavily dependent on metals for the last several hundred years. But the science behind metals has only been discovered in recent years and has now become known to people that we simply could not live without them. Metals make up around 80% of the elements (currently discovered). They are used in everyday items that society depends on‚ such as: cars‚ re-bars for building‚ window

IGCSE Complete Chemistry Notes Unit 1: States of matter Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances‚ when mixed‚ particles bounce off in all directions when they collide. This mixing process is called diffusion. It’s also the movement of particles without a force. The smallest particle

Ruthenium is the 44th element on the periodic table of the elements. Ruthenium was named after the Latin name for Russia‚ Ruthenia. It is a very rare‚ silvery‚ and shiny transition metal found in South America‚ North America‚ and South Africa. Ruthenium was found in 1844 by Karl Karlovich Klaus. In 1808‚ a Polish chemist named Jedrzej Sniadecki found an element he called vestium in platinum ores from South America. When French chemists tried to repeat his work‚ however‚ they did not find it in the
