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

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting

Title: Aim: The aim of this experiment is to test if the rougher surfaces produce more friction and affects the distance travelled of a toy car. The aim of this experiment is to determine if the surface areas affect the distance travelled of a toy car by creating friction between the surface and object. The aim of this experiment is to determine if the surface areas affect the distance of a toy car due to the force of friction between the two objects. Hypothesis: From the basic research shown

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

combination of 20ml of saturated sodium bicarbonate solution and 20ml of ether. Then we drained the lower aqueous layer and we kept the organic layer. We added 4 to 5 pellets of calcium chloride to the organic layer and allowed the solution to dry for 10 minutes. After this we placed the dry ether solution in a 50ml flask and fractionally distilling the solution until the head temperature reaches 90 degrees C. Then we removed the fractionating column and continued the distillation using a short path
