Report Introduction Mummification is an ancient Egyptian method which is a natural or deliberate process intended to dehydrate the body to preserve it. They done this because they believed that if a body was left to rot then it would destroy their soul‚ so they believed that the body needed to be intact to serve as host for the soul. So they preserved bodies so they could use them in the afterlife‚ where the Egyptians believed they would make a journey to another life. To start to mummify a body

1 Class XII: Chemistry Chapter 1: The Solid State Concept 1. Solid: Solid is a state of matter in which the constituting particles are arranged very closely. The constituent particles can be atoms‚ molecules or ions. Properties of solids: a. They have definite mass‚ volume and shape. b. Intermolecular distances are short and hence the intermolecular forces are strong. c. Their constituent particles have fixed positions and can only oscillate about their mean positions. d. They are incompressible

Abstract Gold‚ silver‚ copper‚ lead‚ and mercury are some of the ancient elements. Hennig Brand discovered phosphorus the first element. After the discovery of phosphorus‚ many more elements were discovered. Johann Dobereiner discovered that elements could be grouped in three sets and proposed the Law of Triads. Later‚ A.E.Beguyer de Chancourtois arranged the elements according to their atomic mass and created the first geometrical representation of the periodic table. John Newlands proposed the

combined is the equivalence point. An example of this is shown in the equation: HCl(aq)+NaOH(aq)NaCl(aq)+H2O(l). The number of moles is given by knowing the exact concentration and volume added of the titrant. The latter‚ in turn‚ is related by stoichiometry to the number of moles of acid initially present in the unknown. To detect the equivalence point‚ indicators are usually added to acid-base titrations. The point at which the indicator changes color and signals the equivalence point has been reached

objective was to accurately and precisely convert the unknown sample containing the chloride analyte to another known solid‚ silver chloride. Once the mass of the known solid is measured‚ the percentage of chloride analyte can be calculated using stoichiometry. The chemical reaction occurring in this particular experiment involved the mixing of silver nitrate and the soluble salt in water containing nitric acid. Both reactants break into their ionic components allowing the silver ion and chloride ion

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity
