based on our title name we will use eggshell not any eggshell because we will use chicken eggshell as an alternative ingredient for sidewalk chalk‚ we believe that this study will be great and popular because as of now children‚ students and teachers consume many of chalk which is expensive so we do this study and improve it for children who plays on sidewalk outside their house. * Statement of the problem This study aims to discover the use of eggshells in producing chalk in terms of the

Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Calcium is the largest mineral in the human body‚ where it plays an important role in absorption and the releasing of calcium in the body is through the intestinal and kidney. The calcium in the body is controlled by hormones and vitamins (Takano et al). The three major components that involve in the controller the calcium is parathyroid hormone (PTH)‚ calcitonin and Vitamin D. The consistent the calcium in the body from despite variation in-take and excretion

first discovered in England during the year 1808 by Sir Humphry Davy. He was able to separate calcium into a pure metal by doing an electrolysis process on a mixture of lime HgO‚ which is mercuric oxide. However‚ Sir Humphry Davy was not able to do this until after he found out Berzelius and Pontin electrolysed lime into mercury which constructed calcium amalgam. Although he discovered calcium in 1808‚ calcium metal was not available in large amounts until the beginning of the twentieth century. Before
