solution. 10. Give the balanced net ionic equation for the reaction responsible for the shift in equilibrium for this system. Answer: j. (a) a white precipitate is formed (b) caused by the formation of Cu(OH)2 (c) which is described by the equation Cu2+ + 2OH- Cu(OH)2 since ammonia is present as an aqueous solution‚ thus the reacts w/ the hydroxide part to yield

The headwaters of the Doce River rise in the southeast-east area (SE-E) of the Iron Quadrangle‚ located in south-central portion (C-S) of the state of Minas Gerais (Figure 1). The Iron Quadrangle is historically known as a rich auri-ferriferous province and is a classic region of the world Precambrian geology (Dorr‚ 1959). Its designation results from the area’s planimetric features‚ with a surface area of around 7‚000 km2‚ comprising the most important iron mines of Minas Gerais (Barbosa‚ 1968)

Human Evolution‚ lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people evolved over a period of at least 6 million years. A. From Ape To Man Fossils from several different early australopith species that lived between 4 million and 2 million years ago clearly show a variety of adaptations that mark the transition from ape to human. The very early period of this transition‚ prior to 4 million

Objective: The objective of this lab is to determine and analyze the many chemical qualities of copper ‚ by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper‚ Concentrated HNO3‚ 6 M NaOH ‚ Bunsen burner‚ 6 M H2SO4‚ Mg ribbon‚ and two test tubes. The techniques used in this lab which is cleaning glassware‚ disposing of chemicals ‚ measuring mass ‚ centrifugation ‚ venting gases‚ and test tube
