Hydrogen ion

: The chemical formula of a compound will be determined using the mass of each individual element that is present in a weighed sample of that compound. The chemical formula shows the proportions of elements in a specific compound. This proportion is uniform to all samples of the same compound. Using the mass of each element, the moles of the element in the compound can be found and then compared to that of the other elements. This will create our atom ratio which will lead to our mole ratio. The…

Justin Haynes Organic Chemistry C17H20N4O6 I was given molecule 9. This molecule has the general name of Riboflavin has the chemical formula of C17H20N4O6. This can also go by two IUPAC names the first being 1-deoxy-1-(7,8-dimethyl-2,4-dioxo-3,4-dihydrobenzo[g]pteridin-10(2H)-yl)pen titol. The second name it can also go by 7,8-dimethyl-10-(2,3,4,5-tetrahydroxypentyl)benzo[g]pteridine-2,4(3H,10H)-d ione. While this molecule has the generic name of Riboflavin now .This molecule has been…

It is the non-ideal behavior of gases. On the other hand, the attraction forces within the molecule are called intramolecular forces. (Chang, 2014) There are different types of intermolecular forces. These are dipole-dipole, dipole-induced dipole, ion-induced dipole, and London dispersion forces. The dispersion force, also known as van der Waals force, is the weakest force. It happens when temporary dipoles are induced in atoms or molecules. It usually increases proportionally with molar…

When a hydrogen atom of an alkane is replaced by halogens, they become an alkyl halide compound which can also be called haloalkanes. There are two types of reaction within the alkyl halides. When another atom replaces the halide ion, the reaction becomes a substitution reaction, and when the halide ion leaves with another atom or ion, it becomes an elimination reaction (Weldegirma, 2015). The substitution reaction can be divided into either electrophilic substitution or nucleophilic…

Ammonia is a compound composed of nitrogen and hydrogen, having the formula NH3. The ammonia molecule is formed by sp3 orbitals as it has a tetrahedral geometry and a trigonal pyramidal shape. Ammonia has an experimentally determined bond angle of 106.7°, and an a bond length of 101.7 pm. The nitrogen atom in the molecule has a lone electron pair, which gives the molecule a dipole moment and polarity. Ammonia’s lone electron pair makes NH3 a base, a proton acceptor, and gives it the ability to…

She was a British-born American Astronomer who viewed the spectra of the stellar and solar atmospheres differently than the accepted wisdom of the time. Payne discovered that the stars were composed of mainly Hydrogen and Helium and that they could be classified according to their temperatures. She explained why there were 7 consistently formed absorption patterns from the known stars at the time. She hypothesized that they weren’t created by different combinations…

The first step would be finding the difference of each bond. Hydrogen (H) would be first which is 2.1 the second bond would be chloride (Cl) 3.0 these two values would be taken away from one another 3.0 – 2.1 = 0.9 Then with this value we would mark it on the graph under the electronegativity difference up to the curve…

Salts and molecules have different properties because salts are ionic compounds and molecules are covalent compounds. Justification: Salt is an ionic compound. An ionic compound is formed by ionic bonding between ions of opposite charge. Sodium Chloride and Potassium Bromide are both salts that have an ionic compound. Both elements have the properties of salts which include soluble in water, conductive, and a relatively high melting point. Molecules and Sugar molecules are covalent compounds…

DISCUSSION 6.1 FTIR SPECTROSCOPY It was observed from the FTIR graph that there was no shifting of peaks of metronidazole i,e., characteristic peak of the amine group (N-H streching) present in imidazole nucleus at 1030 cm-1 and presence of NH2 group at 3298 cm-1 in formulation. Hence, there was no interaction between drug and polymer. 6.2 METRONIDAZOLE MICROSPHERES 6.2.1 Optimization of speed (rpm) for preparation of microspheres Metronidazole microspheres were prepared using emulsion…
