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

Mirror and Magnification Equations The mirror equation expresses the quantitative relationship between the object distance (do)‚ the image distance (di)‚ and the focal length (f). The equation is stated as follows: [pic] The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows: [pic] These two equations can be combined to yield information about the

Efficacy of Melgaco Equation in Predicting Permanent Mandibular Canine and Premolars width INTRODUCTION Mixed dentition is the period that includes both the primary and permanent dentition‚ begins at the age of 6 years with eruption of lower 1st permanent molar or lower permanent central incisor and ends with the eruption of 2nd permanent molar. It is necessary to perform mixed dentition analysis because it is used to calculate difference between the space available and space required by the tooth

Scranton Engineers Club. This formula is given as Where σp is pillar strength‚ σ1 is uniaxial compressive strength of a cubical specimen (w/h = 1)‚ and w and h are pillar dimensions. According to Obert and Duvall‚ this equation is valid for w/h ratios of 0.25 to 4.0‚ assuming gravity-loading conditions. Through back calculations from mining case histories and utilization of laboratory rock properties‚ safety factors of 2 to 4 were derived for short- and long-term pillar

Diagonally Implicit Block Backward Differentiation Formulas for Solving Ordinary Differential Equations 1.0 Introduction In mathematics‚ if y is a function of x‚ then an equation that involves x‚ y and one or more derivatives of y with respect to x is called an ordinary differential equation (ODE). The ODEs which do not have additive solutions are non-linear‚ and finding the solutions is much more sophisticated because it is rarely possible to represent them by elementary function in close

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

Fallacies of Equation and Division Fallacies of Equation and Division HU 101 -7G 5/18/13 Instructor: George Strohm Fallacies of Equation and Division First I had to define fallacies of equivocation and division to see where I could possibly start with this essay. Equivocation happens when someone is using a key term in an argument; however the meaning of the key term changes during the course of the argument. "To expose the fallacy of equivocation you give accurate and specific definitions
