Section Assignment 3.4 Part F – The Reaction of Iron Nails with a Copper Solution Introduction: The experiment in this activity involves the reaction between a copper (II) chloride solution with iron nails and the mole ratios involved in the reaction. Measurements are taken to determine the moles of each reactant involved in the reaction and thus the number of atoms or molecules involved. Apparatus and Materials: Refer to the reaction of iron nails with a copper solution assignment in Module

Adolescents are a transitional stage of physical and physiological development that occurs between puberty and legal adulthood.1 It is a period of multiple transitions involving education‚ training‚ employment and unemployment‚ as well as transition from one living circumstance to another.2 The behavioral patterns during these periods determine their health status and their risks for developing chronic diseases in adulthood.3 Adolescents are generally healthy but several important public health and

major changes in decision-making‚ responsibilities‚ and behaviors. It appears there are gender differences between males and females‚ as females appear to go through the major transitions to adulthood at a younger age and leave home faster than men (Holloway‚ 2010). My hypothesis is that females have an earlier transition to adulthood and will leave home at a younger age than males because females have a stronger drive for independence and a readiness to leave their sheltered lives at home and have

Gold is a soft metal that is largely unreactive. Gold jewellery can lie underground for thousands of years and emerge shiny after that lengthy exposure to air‚ water‚ and other chemicals in the environment. Gold does dissolve in some solvents as indicated below and does react with halogens. The most common oxidation states of gold are Au(I) and Au(III) but there are a few examples of Au(V) (various anions [AuF6]- and [Au2F10]). The Au(III) ion has the d8configuration which gives rise to many square

One of the main issues was its narrow bandwidth due to the cut-off frequency characteristic. Later‚ researchers try to find components that could provide greater bandwidth and possible miniaturization‚ and therefore they examined
