textbook in 1789 on chemistry in it he introduced the Law of Conservation. He founded the 3 types of matter (solid‚ liquid‚ and gas). Along with this he also established the metric system. Lavoisier also made a lot of enemies because he had disproved various old theories. In experiment 2.1 we wanted to know if the mass of salt will

Assignment 1b: Rainbows When reading over the possible weather discussion categories the word rainbow stuck out for me. I have always wondered what makes a rainbow‚ and every time I see one I am in disbelief that I’m seeing such a remarkable thing. Rainbows are one of the most beautiful spectacles natures has to offer so beautiful‚ in fact‚ that they’ve inspired countless fairy tales‚ songs and legends. According to Wikipedia.com “Rainbows are optical and meteorological phenomena that cause a

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent

Lab for Chemistry 221 Lab: How much sugar is in a Can of Coke? Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke. Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration
