water | .2 grams | Formula of anhydrous salt | Cu(SO4) – Copper Sulfate | Data Table Calculations 1. Mass of hydrate = 1.38 grams. Mass of anhydrous = 1.08 grams. Mass of water = .2 grams. 2. Ratio of anhydrous mass to hydrate mass is 5.4. 3. Moles of anhydrous salt: 1. 4. Moles of water are five moles. 5. Moles of water per mole of anhydrous salt was about 5.4/1 ratio but really is 5/1 6. Empirical formula for hydrate is Cu(SO4) * 5H2O Conclusion The mass of the anhydrous

Multicomponent Phase Diagrams: Applications for Commercial Aluminium Alloys. Figure 1 Nikolay A. Belov‚ 2005. Multicomponent Phase Diagrams: Applications for Commercial Aluminium Alloys. The alloy is strengthened by the precipitation of hardening Mg and Cu rich phases‚ during ageing heat treatment. As a result the material can be up to 30% stronger‚ when the copper crystals are kept small forcing them to conform to the structure of the aluminium. Silicon is an influential element in the composition

So‚ Pei and co-workers (Pei et al.‚ 2009) found that Cu increases CIP sorption on mineral components kaolinite and montmorillonite in a certain pH range‚ but Ross and Riley (Ross and Riley‚ 1992) showed that Cu increases the mobility and solubility of fluoroquinolones (Chen et al.‚ 2013). Although sediments 5 and 6 have the highest concentration of certain affordable microelements (Cu‚ Fe‚ Zn and Mn) show the lowest sorption potential to CIP‚ this contribution to sorption

Valley. They got into semiconductors in the early sixties and by 1966‚ they entered the computer market with the HP 2100 and the HP1000. These were sturdy models that lasted for a good twenty years before more advancement saw screen keys and the HP 2640 rise to the occasion. (HP.com‚ 2011) 1984 saw the emergence of their first inkjet and laser printers. These were meant for the desktop. Later on in the 90s‚ HP rose in popularity‚ marketing their computers to the average consumer and opening an online

Elements of weather and climate[edit] There are several elements that make up the weather and climate of a place. The major of these elements are five: temperature‚ pressure‚ wind‚ humidity and rain. Analysis of these elements can provide the basis for forecasting weather. These same elements make also the basis of climatology study‚ of course‚ within a different time scale rather than it does in meteorology. Modifying factors of weather and climate[edit] The more important are also five: latitude

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more
