EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic

Stopping Organic Spoilage Grocery owners‚ how much spoilage did you report last year? Anywhere from 15 to 35% of your sales come from produce and fresh vegetables. By my calculations somewhere around 10% or more is thrown out and reported as a loss each year. That is millions of dollars in profits lost from spoilage that can be prevented. Organic spoilage‚ and lack of rotation in stock and merchandise is totally preventable with the introduction of my new system. It is a simple combination of

who mind don’t matter and those matter don’t mind”. At a first glance the quote might be small and obvious‚ but when dissected it has a enormous meaning. The quote gives way to the idea that people who don’t like you can be ignored while people that do like you cannot(Geisel). As Geisel wrote‚ those who matter don’t mind.

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object
