The use of nature is one of the more common themes discussed within multiple stories this term. The use of nature can be instrumental in conveying the symbolic meaning, but it also helps to establish the setting in several stories. Commonly, the author’s use of nature serves a dual purpose within the story, which aids in potentially forming a wide array of interpretations for readers. In the short story Chicxulub, the narrator compares the impact he felt when he received news of his daughter…

Set against the patriarchal backdrop of the Deep South with its norm of male dominance, Alice Walker’s, The Colour Purple, maps the journey the novel’s protagonist, Celie, makes toward self-awareness and freedom. Walker’s epistolary structure highlights the importance of having opportunities to express ones thoughts and feelings in order to develop a sense of self and demonstrates how women have had their voices taken from them. Celie’s growth and the resulting parallel decline of male dominance…

C-H bonds are considered nonpolar. This is because the electronegativity of C is 2.5 and the of H is 2.1, putting their electronegativity in the nonpolar range. O-H bonds are more polar than N-H bonds. This is because the O-H bond is more electronegative because the electronegativity of O is 3.44 while the electronegativity of N is only 3.04.

Title Determining the Empirical Formula of Magnesium Oxide Introduction Chemical formulas imply the arrangement of compounds. Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound.…

I.1- INTRODUCTION: Conformational analysis is the study of the energy change, a molecule undergoes, as it rotates about one or more single bonds. The conformations of a molecule are those arrangements in space of the atoms which are not superimposeable upon each other. The basic idea behind conformational analysis is that molecules will have certain physical and chemical and thermodynamic properties that are dependent on the preferred conformations. in the modern chemistry, where it can…

forces of attraction present in a molecule, the stronger it is. Water and ethanol both have dispersion forces and hydrogen bonding while kerosene only has dispersion force. It means to say that there is a greater energy needed in order to break the bond that holds the molecules together. In conclusion, intermolecular forces increase direct proportionally with increasing polarization. It should also be noted that the arrangement of the strength of intermolecular forces increase from dispersion,…

Paragraph 1 Sphalerite and wurtzite are the two polymorphs of Zinc Sulphide (ZnS). Sphalerite follows the space group F-43m, wurtzite is of the space group P63mc, and both polymorphs have the same formula of (Zn, Fe)S. The crystal chemical relationship between the two can be discussed by looking at the capability of transformation between the two polymorphs, known as polymorphism. This is due to the same SnS4 polyhedral found in both. Yet even though this is so, the two differ when we look at…

Surface modification of CNTs with desired organic, inorganic compounds through covalent or non-covalent bonds represents an emerging area in the research on nanotube-based materials. Such modification can result in a significant enhancement of properties and open up a broad range of novel application perspectives. Non-covalent or covalent functionalization…

PARAGRAPH 1 Comparing the crystal structure of α-FePO4 & β-FePO4 Firstly, the crystal structures of the alpha and beta Iron Phosphate can be identified from the paper. The lower temperature form, α-FePO4, has the space group P3121, while the higher temperature form β-FePO4, has the space group: P6422. These space groups translates to the lattice symmetry of trigonal and hexagonal respectively. The two space groups are chiral. α-FePO4 is the main form of Iron Phosphate in room temperature since…

The infrared (IR) spectra of PVA nanofibers are shown in figure 3-a. According to this figure, polyvinyl alcohol FTIR spectrum has peaks at 1655 cm-1 relating to the bending band of (HOH) peaks in 2910 cm-1 and 2940 cm-1 related to the stretching bands of (CH2) and Peaks at 1710 cm-1 and 1573 cm-1 are related to the carbonyl group. Also, the peak in 1142 cm-1 indicating the presence of oxygen atoms, the band at 1097 cm-1 is assigned to (C-O) stretching vibration of the ether group and peaks at…
