The rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the ensuing metal solutions are tested and the merchandises of the reaction between Ca and H2O is discovered. The tried elements are sodium. Li. K and Ca and each of them were placed in […]

In the geosphere, the content of aluminum is substantial and varies between 7.5% to 8.1% among metallic elements. Deviation from its intended trajectory is rare as the element has a strong attraction to oxygen owing to its high reactivity, leading to a powerful connection with O. This makes separation challenging. Hence, it must undergo the […]

Planning: * There are many ways in which to find out what ions are contained in different compounds. When substance is mixed to make solution, precipitation reactions and reactions with gas specifically are very useful to help us out with identifying which ions are contains in the substances. This test is for negative ions. * […]

The experiment was repeated in order to increase precision. Variables: Controlled: quantity of Magnesium and Taffies used, the volume of cold water used Manipulated: Magnesium, Taffies (metals used) Responding: Products formed due to reaction with each metal with cold water Data to be collected: Table showing the products formed and inference due to the reaction […]

Ductile and malleable are terms used to describe different properties of materials. Ductile means that a material can be easily formed into thin wires, while malleable means that it can be easily hammered into thin sheets. For example, a 20-gram piece of gold can be hammered into a sheet that will cover more than 6 […]

The earliest operation of mining of bog iron in Maine began in Newfield but was a small scale operation but it continued for a long period of time. During the mid 1880’s the other enterprises were near Lubac, that was a lead mine and Katahdin Iron Works. There was a mining boom from 1879 to […]

Engineers and scientists use scientific knowledge to design and build machines that make our lives easier. The machines they build today started off with the basics, which are known as Simple Machines. Simple Machines are defined as the simplest mechanisms that use mechanical advantage to multiply force. These machines have either few or no moving […]

There had been an iron industry in Britain for about 2,000 years. It was on a small scale and located near the source of fuel i.e. charcoal, made mainly from oak trees. The main centres of production were the “Weald” in Sussex, the Forest of Dean and the “Wrekin” in Shropshire. During the 18th Century […]
