The heat from the bunsen burner will remove the oxygen atoms from their positions in the ionic structure and will make the elemental forms of silver and oxygen (O2). The heat speeds up the process of breaking the attractions‚ because the electrons need to overcome an activation energy to break the bond‚ and therefore will force the ions away

Edible Atom Summary Sulfur Element number 16 on the periodic table of elements is sulfur. Sulfur is known as a brimstone‚ meaning “burning stone.” This is because it is found in deposits near volcanoes‚ and it burns very easily. It is found naturally around hot springs‚ volcanoes and in meteorites. Sulfur is also a mineral that you will find in all the cells of the human body. Sulfide bonds are the key bonds that allow curly hair to stay curly‚ and if you ever get a “perm” they add sulfide bonds

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

Purpose: To use electrochemistry to extract metals from ionic compounds in solution Procedure: -Start by attaching battery snap connector to a battery and fill beaker with between 100 and 200 mL of copper (II) sulfate solution -Connect clip to each of the nickel strips -Place nickel strips in copper sulfate solution without strips touching -Put one clip on the positive side of the battery and the second to the negative side. Observe -Switch clips to the opposite charged sides of the battery

Almost everything that happened in ancient Greece influenced us‚ but art and architecture is the area the Greeks made the biggest contribution. To begin with‚ the ancient Greeks influenced the way many of the sculptures are today. The sculptures that were men were called Kouroi‚ the women were called Korai. Back in ancient Greece the sculptors began to create and sculpt their statues in more relaxed postures. Occasionally‚ they constructed their sculptures in an action scene. Sculptors oftenly were
