Chemical Bonding and Structure In his essay I will be discussing the scientific background and explanation of chemical bonding and structure‚ I will also be describing the method of injection molding and its benefits and limitations and how it is superior to the previous methods of making plastic. Finally I will also list the implication effect of plastic and its effect (economically and environmentally) A chemical bond is the result of a lure (attraction) between atoms or ions

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to bring

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. (b) Change of colour of substance

“Chemistry is the study of matter” Its brief meaning explains it all. Chemistry is a science that deals with matter‚ its composition‚ and changes they undertake. Chemistry has been part in our lives ever since. It contributes to our existence‚ our culture‚ and our life. Chemistry explains why changes happen around us. All living processes are chemical reactions. It helps in sustaining our needs. Through this we are able to feed the world’s population‚ medicines to cure diseases and improve
