Separation of Iron‚ Salt and Sand Separating a mixture is an example of a physical change. There are several ways to separate a mixture. The use of one’s hands in pulling the parts of a mixture apart is one example. Filtration is another way to separate mixtures. Filtration is the separation of a heterogeneous (not alike‚ different) mixtures‚ by adding a solvent and passing the resulting mixture through a fine mesh or filter. Evaporation of a homogeneous (alike‚ same) mixture will reveal

Elements and compounds are a result of the actions of the valence electrons. There are three types of bonds that I have learned about in the bonding comparison lab. These bonds include ionic‚ polar covalent‚ and non-polar covalent. Each of these bonds and the element compounds connected to them has individual solubility‚ conductivity‚ melting point‚ and volatility levels. The three element compounds that will follow are sodium chloride‚ sucrose‚ and p-dichlorobenzene. Sodium chloride is an ionic

In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2.

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Atomic energy is energy produced by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility ofatomic energy.[1] The term was popularized by H. G. Wells in the phrase‚ "splitting the atom"‚ devised at a time prior to the discovery of the nucleus. Atomic energy also may refer to: * Nuclear binding energy‚ the energy required to split a nucleus of an atom * Nuclear potential energy‚ the potential energy of the particles inside an atomic nucleus * Nuclear

On August 6‚ 1945‚ the United States of America dropped an atomic bomb on Hiroshima‚ Japan. The United States was justified to do this because of the unprovoked attack and bombing of Pearl Harbor‚ Hawaii‚ which occurred three years prior to the bombing of Hiroshima‚ and it was necessary to stop the war because it saved thousands of American lives. Until then‚ the fight had never been on United States soil. The innocent civilians of Japan did not have to worry about being killed on their land until
