aspect and institutional and environmental constraints add to the complexity of IHRM (Brewster et al.‚ 2007). The aim of this coursework is to scrutinize various IHRM strategies adopted by MNCs in the face of various environmental and institutional circumstances and to reveal the pros and cons of the seemingly neutral façade of the IHRM strategies. The layout of the coursework will be based on the ‘Eight-point star of IHRM: a framework of key aspects’ (Figure 1) which identifies the eight distinct and

1. (a) I‚ III‚ and IV are correct. II is not correct. To explain III‚ de Broglie’s equation states l = h/(mv)‚ so nl = nh/(mv) = 2pi(r). Where: l = wavelength‚ v = velocity of electron‚ n = some positive integer‚ r = distance of electron from center‚ m = mass of electron. Solve‚ get mvr = L = nh/2pi. (b) The current wave mechanical model for the atom states that there are an integer number of wavelengths in every standing integer number (n). 2. (a) The first shell electrons in Lithium are

factors affecting the rate of a chemical reaction. Introduction: In my coursework I will be mainly concentrating on the reaction between dilute hydrochloric acid with marble chips (calcium carbonate). Calcium carbonate (marble chips) + hydrochloric acid ==> calcium chloride + water + carbon dioxide CaCO3(s) + 2HCl (aq) ==> CaCl2 (aq) + H2O (l) + CO2 (g) Aim: The aim of the experiment is to investigate how the concentration of hydrochloric acid affects the rate of reaction with marble chips‚

Chemistry 12: Reaction Kinetics Review 1. Looking at the expressions for reaction rate‚ write expressions with which you could express rates for the following reactions. (Hint: look at what happens to reactants and products.) Recall that solid or liquids can lose or gain mass‚ gases can lose or gain volume and aqueous solutions can increase or decrease in concentration. ("a" is done as an example.) a) Mg(s) + 2HCl(aq) H2(g) + MgCl2(aq) reaction rate = mass of Mg consumed unit time b) c) or

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will
