Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

Experiment 3: Stoichiometry of a Precipitation Reaction Abstract: In this experiment‚ the objective is to use Stoichiometry to predict the amount of product produced in a precipitation reaction. We received working knowledge of how to accurately measure reactants and products of the reaction. We then are able to use the data that we recorded to make assessments of the actual yield opposed to the theoretical yield. When we calculated the percent yield we are able

6: The Copper Cycle CHEM 101 Lab-M/630 As an investigation of the copper cycle lab group 6 conducted an experiment on 6 October 2014 at Arizona State University laboratory that would demonstrate the cycle of reactions that copper (Cu) can produce when introduced to with other substances/reactant. The purpose of the investigation was to notice the transformation of a specific quantity of copper wire (g) as it undergoes its coordination reactions until a reduction method would yield copper (Cu) again

In this lab‚ we changed copper into various forms using different chemicals and chemical reactions. The purpose of this lab is to demonstrate that the product of a chemical reaction depends on what is present at the time of that reaction. This lab also displays how matter cannot be created nor destroyed in a chemical reaction. In a lab‚ you must always make safety a priority in case of an emergency. In our lab‚ we made sure to wear closed-toed shoes as well as goggles at all times. We also performed

When the supply ship docked‚ the gift Jamie received was a copper flute which he immediately began playing. Explain how the seal hunt illustrates Jamie’s feelings towards wildlife. The seal hunt illustrates Jamie’s feelings towards wildlife because when he saw the seal die‚ he was enraged immediately and spontaneously

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around
