Acidic Oxide – SULFUR DIOXIDE Industrial Process – Sulfur Dioxide is an acidic oxide produced domestically and industrially in many ways. Xstrata‚ particularly Mount Isa Mines LTD‚ produces sulfur dioxide as a by-product from the extraction of copper from ores. Copper ore mined in Australia is predominantly chalcopyrite (CuFeS2)‚ a sulfide ore of copper. The extraction of copper begins with crushing the ore and subjecting the crushed ore to froth floatation. In this the concentrated copper ores

The Fry Graph Readability Formula Edward Fry developed one of the more popular Reading Formulas – the Fry Graph Readability Formula. Fry‚ who worked as a Fulbright Scholar in Uganda‚ also helped teachers to teach English as a Second Language (ESL) for a few years‚ from 1963 and onwards. During his early days‚ Fry developed readability tests based on graph [A Readability Formula That Saves Time‚ Journal of Reading (1968)]. This graph-based test determined readability through high school; it was validated

Experiment 6 Title: Preparation of bis(acetylacetonato)copper(II) complex Objective: To synthesize the bis(acetyacetonato) copper(II) complex Theory/Background: All metal ions in solution are ’associated’ with water. The water molecules can also be weakly bonded or more strongly as a ligand to form a complex ion‚ and these can also present in solid ’hydrated’ salts of crystallization. E.g Copper(II) nitrate (Cu(NO3) 2.3H2O). A complex ion has a metal ion at its centre with a number

The speaker’s that impact me a lot is Joanna Farris and her story that is meaningful to me is that‚ she talks a lot about breed-feeding and how some women taught of breed-feeding VS formula feeding. They speaker talk about the importance of breed-feeding‚ how breast-feeding is healthiest for mom‚ how breastfeeding saves money‚ how breastfeeding is healthiest for babies‚ WIC provides good food and a whole lot more‚ how often should mothers breastfeed my babies‚ how colostrum is good for baby‚ how

Advanced Formulas and Functions in Microsoft Excel This document provides instructions for using some of the more complex formulas and functions in Microsoft Excel‚ as well as using absolute references in formulas. Opening Comments Formulas are equations that perform calculations on values. A formula starts with an equal sign (=) and follows the order of operations (parentheses‚ exponents‚ multiplication & division‚ addition & subtraction). For example‚ the following formula multiplies

Lillian Zhang AP Chemistry 3rd Period Formula of an Unknown Hydrate The purpose of the Formula of an Unknown Hydrate lab is to determine the weight percentage of H2O hydrated to an unknown salt and the empirical formula for the hydrated salt. To do this‚ a massed amount of the hydrate is heated over either a hot plate or Bunsen burner. This causes the water to be removed‚ leaving the anhydrous salt behind in the dish. The mass of the anhydrous salt‚ now with the absence of water‚ is less than

DETERMINATION OF THE CHEMICAL FORMULA FOR A HYDRATE USING MOLE RATIO OF WATER MASS AND MAGNESIUM SULPHATE INTRODUCTION Ionic (salt) compounds are able to hold loose bonds with water molecules. A hydrate is a compound that incorporates water molecules into its crystalline lattice structure (McGraw-Hill Ryerson‚ 2014). Identifying a compound as hydrated or anhydrous is important as the mass of the compound increases if it contains water molecules. In nature‚ hydrates exist with a fixed ratio
