definition of fiber may be needed. New products are being developed or isolated that behave like fiber‚ yet do not meet the traditional requirements of fiber‚ either analytically or physiologically. Without an accurate definition of fiber‚ compounds can be designed or isolated and concentrated using available methods without necessarily providing beneficial health effects‚ which most people consider to be an important attribute of fiber. Most of us are familiar with the terms "soluble fiber" and "insoluble

A Sequence of Chemical Reactions: Transforming Copper Briefly describe. a) Why must you carry out the oxidation of Cu with HNO3 in a fume hood? Concentrated nitric acid is a toxic oxidant. Avoiding skin contact or inhalation is highly important. The reaction between Cu and HNO3 produces NO2‚ a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas. b) Why you should be particularly careful when you work with 3 M H2SO4 solution?

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

Coursework 4 Copper Name of student: Alfiya Ospanova Tutorial group: G Copper is one of the earliest elements explored by humanity. Due to the special red shade it was easy to find in ancient times. The metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper).

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here
