Stephany Matos Chem Lab: Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]/([Fe3+]•[SCN-] For this experiment we were able to determine the equilibrium constant KC for this reaction. First we prepared five different mixtures with known initial concentrations of

Matter and its Properties Basic Building Blocks of Matter The fundamental building blocks of matter are atoms and molecules. These make up elements and compounds. An atom is the smallest unit of an element that maintains the properties of that element. And element is a pure substance made of only one kind of atom. A compound is the substance that is made from the atoms of two or more elements that are chemically bonded. Water is an example of a compound because it is one of many compounds that

Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestion process also involves creating waste to be eliminated. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of by muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver

a flow chart for a process Zoey Johnson University of Phoenix OPS/571 October 27‚ 2012 One process that seems to be a never ending process in my daily life is doing laundry. With a household of six people‚ the laundry needs to be done daily or else it will overtake the house quickly. To help illustrate the laundry process I have used Microsoft Word to create a flowchart that depicts the process. Using flowcharts is valuable because the flow of logic is shown throughout the process. Much like

Nutrition is a process; it is how the body puts all the processes together in order to provide what our bodies need to be healthy‚ to grow and to maintain good health while supplying all our nutritive needs. There are different stages to nutrition‚ it starts with the food we ingest‚ then it is digested‚ it can then be used and absorbed by the body and is then assimilated and finally any waste is eliminated. At the first stage of the process is ingestion and it could be argued that good nutrition

To achieve the goal of providing energy and nutrients to the body‚ six major functions take place in the digestive system ingestion‚ Secretion‚ mixing and movement‚ digestion‚ absorption and excretion. There are two kinds of organs that make up the digestive tract are the mouth‚ esophagus‚ stomach‚ small intestine‚ large intestine also called the colon - rectum‚ and anus all of which are hollow. Inside these hollow
