Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

Systems of linear equations‚ or a set of equations with two or more variables‚ are an essential part of finding solutions with only limited information‚ which happens to be exactly what algebra is. As a required part of any algebra student’s life‚ it is best to understand how they work‚ not only so an acceptable grade is received‚ but also so one day the systems can be used to actually find desired information with ease. There are three main methods of defining a system of linear equations. One way is

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

Quadratic equation In elementary algebra‚ a quadratic equation (from the Latin quadratus for "square") is any equation having the form where x represents an unknown‚ and a‚ b‚ and c represent known numbers such that a is not equal to 0. If a = 0‚ then the equation is linear‚ not quadratic. The numbers a‚ b‚ and c are the coefficients of the equation‚ and may be distinguished by calling them‚ the quadratic coefficient‚ the linear coefficient and the constant or free
