It was determined that Substance A is a covalent molecular substance as it is a liquid at room temperature and therefore has a low melting point which is a property of a covalent molecular substance. Substance B was found to be a metallic substance as it demonstrated properties such as high melting point, conductivity as a solid etc. Substance C was found to be a covalent network structure as it did not conduct and was very hard and had a high melting point. Both Substances D and E were very…

: 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…

are bonded. Then they would draw the line over to the percentage on this occasion it would be 18% Ionic and to work out the other bond one would take 100- 18= 82% which would be covalent bond. We can do this again with another bond let’s look at lithium fluoride (LiF) Li = 1.0 fluoride equals 3.0 let’s take them away 3.0 – 1.0 = 2 if we use the graph it can be said the ionic bond percentage is 61% now again to find the other bond one would take 100 away from 61%, 100 – 61 = 39% so here it is…

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…

31. cis/trans isomers Isomers are compounds with a similar substance recipe however extraordinary structures. The structures of these isomers vary in the introduction of the two chloride particles around the Co3+ particle. In the trans isomer, the chlorides involve positions opposite each other in the octahedron. In the cis isomer, they possess contiguous positions. The distinction amongst cis and trans isomers can be recollected by taking note of that the prefix trans is utilized to portray…

Overall the experiment provided significant data, despite problems with reagent contamination. Iron (III)-thiocyanate complexes in equilibrium, meaning that external and internal forces on the equilibrium can shift toward the reactants or the complex. External forces are changes to the chemical or physical environment that effect the equilibrium. Internal forces are changes to the bonds or chemical nature of the complex itself. These effects are used to study the optimal chromogenic reagent,…

1.3. AMORPHOUS STATE The amorphous state of solids is composed of molecules that have a disordered arrangement, which do not constitute to the characteristic of the crystal grid and, therefore, have zero crystallinity. The distribution of molecules in the solid amorphous form is not entirely random as it is specific to a gaseous state because it has a certain degree of order between neighboring molecules. Due to the lack of regulation and the absence of a crystal grid, compared to the crystal…

Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…

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…
