(Name) (Course Name) (Instructors Name) (Date) Summary of chemistry lab report Introduction The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food

esophagus‚ and stomach. 2 These harsh qualities are alleviated by replacing the acidic hydrogens with less reactive groups of atoms: the acetyl group (COCH3). This results in acetylsalicylic acid or "aspirin". Acetylsalicylic acid is synthesized in labs and does not occur naturally. It is produced from adding acetic anhydride to salicylic acid in the presence of sulfuric acid (H2SO4)‚ an acid catalyst: (Diagram from 1) The impurities left over (unreacted salicylic acid‚ acetic acid and sulfuric acid)

ZEIT 1206 DEC1 Lab Report 1 DC Circuits - Analysis and Design Alexander Glover‚ z3422512 Abstract DC circuit analysis and design‚ play a massive role in electrical engineering and without the correct application of theory and practise in unison‚ nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes. The ability

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules

3DIFUSSION IN AGAR CUBES – LAB REPORT Research Question: What is the effect of surface area on volume ratio on the rate of diffusion of pigment from the agar cube measured by percentage volume of diffusion over time? Background Research: Diffusion is the passive movement of molecules or particles along a concentration gradient‚ or from high to low concentration regions. Essential towards living organism’s functions‚ as it describes how the nerve cells are able to communicate with each other‚ through
