Purpose: The purpose of this lab is to identify the presence of cations and anions in four unknown solutions by identifying whether they are copper‚ silver‚ iron‚ or chloride ions which is done by adding sodium hydroxide‚ solid copper‚ silver nitrate‚ and potassium thiocyanate to the solutions and analyzing the chemical reactions. Introduction: Chemical change‚ unlike physical change is the change in the composition of a substance rather than simply its shape‚ size‚ or state (Marie‚ 2015). Signs

processing or conventional productions of finer precipitation calcium carbonate (nano-PCC) in turbo-mixing conditions. In this paper‚ the effect of the stirring rate onto morphology‚ particle sizes and reaction time of the precipitated CaCO3 particles was discussed. CaCO3 nano particles with an average particle size of approximately 15.75 nm were successfully obtained by stirring rotation speed at 900 rpm. The structural analysis was conducted using a Scanning Electron Microscope (SEM) and a Field

Lab 9: Analysis of Commercial Bleach Introduction Many common products are effective because they contain oxidizing agents. Some products‚ which contain oxidizing agents‚ are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (or NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized from the molecular form (Cl2) to the

In the film Full Metal Jacket there are many leaders. The two I will focus on are Sergeant Drill Instructor (SDI) Hartman and ‘Joker’. They are two leaders with very different leadership skills. SDI Hartman is a strict and demanding leader who belittles his recruits to get their attention. Joker is a likeable character with a sense of humor and leads with honor and dignity. Both characters portray leadership skills to Private Pyle but the differences are night and day. The beginning of the

Humans all contain that good verses evil‚ that little devil on the left shoulder and the angle on the right‚ talking to people during any given choice in life. The film “Full Metal Jacket” demonstrates the duality of man and symbolizes in many ways the shaping of a human beings mind and character to one side or another. Sergeant Hartman starts the film with a remarkable motivational speech setting a definite tone on how the
