Organic Lab 2 February 14‚ 2009 Experiment 4: Borohydride Reduction of 2-Methylcyclohexanone Introduction: When learning about reduction reactions‚ we know that the addition of nucleophilic hydride anion (H-) to the carbonyl group will in turn result in the reduction of aldehydes to primary alcohols. Borohydride‚ and Lithuim aluminum hydride are commonly used as reducing agents. We can note that both of these reagents have a (H-) anion‚ hence it will be a powerful base and also take the

The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment‚ such as "operating a grinder‚" "using a pressurized water extinguisher‚" or "changing a flat tire." JHAs are not suitable for jobs defined too broadly‚ for example‚ "overhauling an engine"; or too narrowly‚ for example‚ "positioning car jack." What are the benefits of doing a Job Hazard Analysis?

Sacramento tap water reveals ion concentrations of various different dissolved minerals such as calcium (Ca2+) and magnesium (Mg2+). These concentrations are a result of mineral deposits in local lakes and rivers. Perma Pure‚ a gas conditioning products manufacturing company‚ simplifies the mechanism of ion exchange by explaining that water is a solvent that dissolves most ionic bonds when exposed to compounds ("The Mechanism of Ion Exchange"). Therefore‚ as tap water passes through rocks it will

Science Lab Report Conclusion Ms. Seaward Jeneé S. White May 16‚ 2015 How Light Refracts Throughout Water My experimental question for my project is: Would light bend at a refractive angle after it propagates through water? The resolution to my experimental question is that light does bend at a refractive angle after it propagates through water. My hypothesis for my project is: I hypothesize that light will bend because of real world examples and experiments. One instance is light refracts

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

This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests.

respiration occurs with oxygen‚ it is called aerobic respiration; this is what most organisms require. In the end‚ the food molecules are broken down with water and carbon dioxide. The energy of the food molecules are released and stored in the ATP bonds. The chemical equation for aerobic respiration is: Glucose + water+ oxygen àcarbon dioxide + water +energy +heat. My prediction for this experiment is that if the mealworms are at a cold temperature‚ then their breathing and metabolic rate would slow

(3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead
