Lab #2 – Separation of a Mixture of Solids Abstract The mixed solution contained benzoic acid‚ iron‚ table salt‚ and sand. When separated using water‚ fuel‚ or a magnet‚ their characteristics and properties changed. The mass of the entire mixed solids was 6.6 grams. When the magnet was used‚ the iron was immediately picked up. The mass for that was 1.7 grams. The table salt was 1.2 grams. Benzoic acid mass was 0.8 grams and the sand was 1.4 grams after being separated. Introduction The objective

Separations of the Components of a Mixture January 9‚ 2013 Hailey Rounds Partners: Kelsy Shay Katie Nelson Objectives: The purposes of this experiment are to separate two components in a mixture‚ specifically sodium chloride and silica‚ and find the correlating percent composition of each. Abstract: This experiment consisted of the separation of sodium chloride and silica. The mixture was separated by extracting the sodium chloride with water and drying both substances. Adding water to

Michael E Porter’s Five Forces of Competitive Position Michael Porter’s famous Five Forces of Competitive Position model provides a simple perspective for assessing and analysing the competitive strength and position of a corporation or business organisation. Here is a brief introduction to Porter and his work in this space. American Michael Porter was born in 1947. After initially graduating in aeronautical engineering‚ Porter achieved an economics doctorate at Harvard‚ where he was subsequently

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized

Separation of a Mixture of Solids I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a substance dissolves depends mainly upon the physical properties of the solvent and of the solute and to some extent upon the solvent’s temperature. With that being said I came

Have you ever thought what religion is and what importance in our lives it has? We could say that religion is a set of beliefs‚ cultural systems‚ and worldviews concerning the cause‚ nature and purpose of life and the universe‚ especially when considered as the creation of a supernatural agency or human beings’ relation to that which they regard as holy‚ sacred‚ or spiritual. In other words we could say that religion is the struggle of man in his inner world. Religion starts where the science ends
