Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

Who is to say where the line is to be drawn? The line of morality‚ that is. The concept of “morality” is no longer taken into account by it’s literal meaning. Today’s new morphed definition of morality creates a deadly combination when brewed with modern time expressions of “feminism.” That is the problem right there. The world cannot come to precise terms with these two important concepts of “morality” and “feminism.” This is the reason for so much hypocrisy and controversy. There is certainly

Double-entry journals Journal writing is a way to record your thoughts. They can record personal responses to everyday experiences‚ like diaries‚ or they can record intellectual responses to academic work‚ like the double-entry journals you’ll be keeping during our study of various texts. Disciplining yourself into writing down your questions‚ observations‚ emotional reactions‚ and reflections helps you read more deeply and sort out what’s going on‚ at the surface level of the story and beneath

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

Sebastian reached into his bag of tricks once more and pulled out a hatchet. The blade was so sharp it could easily cut the whiskers of a cat. The madman began to repeatedly dig the hatchet into a tree and with a simple shove he sent the tree crashing to the ground. With a big thud the tree collided with the dirt road blocking it off to anyone who tried to take this road. We descended back into the forest and using our magic created a shelter out of leaves and sticks that would suffice for a couple
