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

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

Closed system growth curve Closed System Growth Curve Lab Report PURPOSE Bacteria grown in a closed system show a specific growth pattern called the growth curve which consists of four phases. The lag phase‚ which is a period of slow growth; exponential phase‚ period of maximum growth; stationary phase‚ where nutrients become the limiting factor making the growth rate equal to the death rate and the death phase where organisms die faster than they are replaced. It is important to know how fast

By rearranging this equation and taking logs we can form “log(Par/(1-Par))=[A]-logKA” from which we can see that plotting log (Par/1-Par)) against log [A] forms what is known as a hill plot‚ which consists of a straight line with a slope of unity. If the relationship between drug concentration and tissue response is directly proportional‚ the relationship between occupancy and response can be denoted as Y/100= Par which can be substituted into the previous equation to provide log(y/(100-y))=log[A]-log[KA]

IB Physics Internal Assessment Andy Tang Research Question In this internal assessment‚ I am given a cantilever to find the physical properties of it. I decide to investigate the relationship between the force I act on one side of the cantilever and the maximum acceleration the tail can reach. This experiment will be also showing the elasticity of the cantilever. Since I pull down one side of it and fixed the other side‚ when I cut the string‚ it will bounce up and down until all the internal
