The poem harmonium examines the relationship of a father and son. I think Armitage has written this poem for parents and children as they would be able to relate to the emotions in the poem. The Author uses the Farrand Chappelette which is a type of Harmonium or small organ to help him reflect the love that he has for his father. In the first stanza the poet talks about the Farrand Chappelette which was “gathering dust” telling us that it is getting old and it was due to be taken to the skip if Armitage

3.6.2. Hygroscopicity assessment of free films Free films were evaluated for hygroscopicity behavior to understand the contribution of lactose and sodium chloride on hygroscopicity‚ if any. It was found that HPMC SD and HPMC-LAC CP films were ‘moderately hygroscopic’ whereas HPMC-NaCl CP films were ‘very hygroscopic’. The percentage moisture content and classification of each sample as per Callahan et al. (Callahan et al.‚ 1982; Murikipudi et al.‚ 2013) has been listed in Table 5. 4. Discussion In

Introduction: The purpose of experiment 1 was to demonstrate the principle of simple diffusion and understand how to make % solutions. Exercise 2 demonstrated the principle of osmosis: observing the movement of water by osmosis from an area of lower concentration of a solute to an area of higher concentration of a solute. Materials and Method: Refer to pages 47-51 of Bio 203L Lab Manual. Results/ Discussion: The effect of the chloride ion on its rate of diffusion in agar means it will diffuse

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H‚ it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s‚ it is organic. Use the naming organic compounds rules. *

The Effect of Molecular Weight on the Rate of Diffusion of Potassium permanganate (KMNO4)‚ Potassium dichromate (K2Cr2O7) and Methylene blue ¹ ABSTRACT The effect of molecular weight on the rate of diffusion was determined using the Agar-water Gel Test. One drop of potassium permanganate (KMNO4)‚ potassium dichromate (K2Cr2O7) and methylene blue were used. Each substance has a respective molecular weight of 158 g/mol‚ 294g/mol and 374 g/mol. The diameters (in millimeter) were measured
