Purpose: The purpose of this lab is to develop a deeper understanding of LeChatelier’s Principle by observing several systems at chemical equilibrium and interpreting the effects of varying concentrations and temperature. The principle states that if systems at equilibria are altered or disturbed in any form‚ the equilibria will shift to reduce the disturbing influence ( Catalyst‚ 186). In a 3 part experiment‚ we analyzed the outcome of changes in reactant and product concentrations‚ equilibrium

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

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
