Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

materials include wood shavings‚ sawdust‚ peanut hulls‚ shredded sugar cane‚ straw‚ and other dry‚ absorbent‚ low-cost organic materials. Sand is also occasionally used as bedding. The bedding materials help absorb moisture‚ limiting the production of ammonia and harmful pathogens. The materials used for bedding can also have a significant impact on carcass quality and bird performance.[1] There are specific practices that must be followed to properly maintain the litter and maximize the health and productivity

This composes the upper 25% of the planet. Next‚ the hydrogen thins out into the gaseous atmosphere which is 1000 km (620 miles) deep. It is composed mainly of hydrogen and helium with trace amounts of methane‚ water‚ ammonia‚ and hydrogen sulfide. Some scientists believe that there are also polysulphur compounds and phosphine which lend their colors to the clouds. Jupiter also has a faint ring system. It is comprised of one main ring‚ with fuzzier "gossamer" rings farther

Chlorine in the pool reacts with organic matter‚ such as urine‚ sweat‚ and saliva‚ to produce disinfectant by products (chloramines). The main chloramines found in pools is nitrogen trichloride (NH3 + 3 HOCl → NCl3 + 3 H2O) ammonia (NH3). Nitrogen trichloride is the most vaporous chloramine and is easily released into the air‚ this gas causes reactions experienced by some swimmers. Recent studies suggest that long-time exposure to these chloramine compounds can cause the skin

The natural gas industry in Trinidad and Tobago began with the discovery of gas on land at Mahaica in 1955 by Dominion Oil‚ however the first major natural gas discovery (One Trillion Cubic Feet (Tcf)) was off the East coast of Trinidad by Amoco in 1968 in the Teak offshore field. This was followed up in 1973 by a 2 Tcf find in the South East Galeota acreage. There was however production and utilization of gas before this date. Although the dates referred to mark the first large finds of natural

Lesson 2 History Of Refrigeration – Development Of Refrigerants And Compressors 1 Version 1 ME‚ IIT Kharagpur The objectives of the present lesson are to introduce the student to the history of refrigeration in terms of: 1. Refrigerant development (Section 2.2): i. ii. iii. Early refrigerants (Section 2.2.1) Synthetic fluorocarbon based refrigerants (Section 2.2.2) Non-ozone depleting refrigerants (Section 2.2.3) 2. Compressor development (Section 2.3): i. ii. iii. iv. v. vi. Low-speed

(can attain 60-85% BOD removal) and have relatively short retention time (for BOD of up to 300 mg/l‚ one day is sufficient at temperature >20oC). Anaerobic ponds reduce N‚ P‚ K and pathogenic micro-organisms by sludge formation and the release of ammonia into the air. As a complete process‚ the anaerobic pond serves to: * Separate out solid from dissolved material as solids settle as bottom sludge. * Dissolve further organic material. * Break down biodegradable organic material. * Store

the reagents used in the synthesis procedure‚ you can assume that the final compound contains copper(II)‚ ammonia‚ sulfate‚ and water. In your analysis‚ you goal is to figure out the mole ratio of each component in the final compound. In other words‚ you will solve for x‚ y‚ z and a in the formula Cux(NH3)y(SO4)z • aH2O. Based on the way the formula is written you can assume that ammonia
