The band gap value of the DBAP molecule was calculated as 5.60 eV‚ which indicates that the DBAP molecule has stable molecular structure and the value is comparable with the band gap energy value of the reported bio-active molecules [16]. The higher hardness and lower softness value indicates the stability of the DBAP molecule. The obtained lower chemical potential and electrophilicity index values are comparable with the potential bioactive molecules [14‚ 16]. DOS spectrum was also simulated by

Abstract This laboratory involved utilizing equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data

1. Solution is a homogeneous mixture composed of only one phase. In such a mixture‚ a solute is a substance dissolved in another substance‚ known as a solvent. Suspension is a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye and eventually‚ they settle out of the mixture. A colloid is a substance microscopically dispersed throughout another substance. Unlike colloids‚ suspensions will eventually settle. The suspended particles are visible

2. Effect of Ocimum sanctum leaves extract on memory impairment by Scopolamine in test (TE) session using time spent in green arm as a parameter: In order to determine the effectiveness of Ocimum sanctum leaves extract‚ comparison of time spent in the food containing green arm in test session of ocimum sanctum groups‚ OTE and SOTE with the only scopolamine treated group (STE) was carried out. The time spent in the food containing green arm of OTE and SOTE were found to be 109 sec and 93 sec respectively

Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you put sugar

Determining the Concentration of a Solution: Beer’s Law Purpose: The purpose of the experiment is to determine the concentration and formula of an unknown cobalt nitrate solution by measuring absorbance. Introduction: A Colorimeter will be used to determine the concentration and formula of an unknown cobalt nitrate solution. The colorimeter sends blue light from the LED light source to pass through the solution and hit a photocell. A solution with a higher concentration will absorb more

Product Orientation to Solution Orientation: A Journey Most industrial goods manufacturers and other organizations operating in B2B markets currently face testing times owing to bad economic conditions. While the economic downturn threatens the growth of a lot of these B2B businesses‚ other factors have also emerged that have contributed to this situation of the “perfect storm”. Increased price competition from the traditional low-labour countries‚ increased product quality levels from these same

Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary‚ we were trying to find out how osmosis actually occurred in potatoes‚ and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction

MIXTURES‚ SOLUTIONS‚ SUSPENSIONS AND COLLOIDS MIXTURES A mixture is a combination made up of two or more different substances which are mixed but are not chemically bonded. There are also types of mixtures such as homogeneous mixtures and heterogeneous mixtures. SOLUTIONS A solution is defined as a homogeneous mixture composed of a solute; a substance dissolved into another substance known as a solvent. They can also be defined as groups of molecules that are mixed up completely in even
