Laboratory Work

Conclusion The purpose of this lab was met because the atomic mass of “Pentium was calculated using the isotopes of Pentium- the ones that were made before 1982 and the ones that were made 1982 and after. The average mass of a pre-1982 penny was grams, and the average mass of a post 2 penny […]

Mental health is everyone’s business. We all have times when we feel down, stressed or frightened, but for most of us those feelings pass with time. Unfortunately sometimes they develop into a more serious problem and that could happen to any one of us.This assignment looks at mental health and mental illness. It defines the […]

Define dehydrating of explosives mixtures. Dehydration of explosives is the process of removing water from the explosive compound to reduce the amount of dilution that water would add to the mixture. It can be done by De-waters, hydraulic press and alcohol as well as other means. 1. What constitutes the incorporating process of explosives manufacture? […]

This study was undertaken to determine the relationship between of light intensity and rate of photosynthesis in spinach leaves. Rate of photosynthesis was determined at pH 7, 0.2% NaHCO3, room temperature, and under white light using light intensities of 2200, 4250, 5300, 14400, 20600 lux. The amount of oxygen production was determined after five minutes […]

This graph indicates that as the time increases the concentration of sulfur dioxide in wine also increased. This opposed the hypothesis as it was predicted that as the time increased the concentration of sulfur dioxide in wine would decrease. Conclusion: The purpose of this experiment was to see how the concentration of sulfur dioxide as […]

The question asks us to determine DE, given information about q and w. Plan We first determine the signs of q and w (Table 5. 1) and then use Equation 5. , DE = q + w, to calculate DE. Chemistry, The Central Science, 12th Edition Theodore L. Brown; H. Eugene Lemma,Jar. ; Bruce E. […]

Objective The objective of this experiment is to study Newton’s Second law of motion utilizing the Atwood Machine and to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the […]

The purpose of this text is to examine a classroom conversation between a teacher and two students, with a focus on turn-taking. Specifically, the analysis will explore instances of overlap and interruption when speakers take turns. The selected episode for analysis comes from a textbook used for discourse analysis. This conversation occurred during a university […]

This chapter examines the materials and procedures utilized to collect essential information and data for the study. The bacterial isolates (Staphylococcus erasures, Escherichia coli, and Streptococcus) used in the experiment were obtained from the Institute of Biological Science, University of the Philippines Los Banos, Laguna. The bacterial isolates were subcultured on slants of Nutrient Agar […]

The purpose of the laboratory experiment was to observe the qualitative aspects of a copper reactions series. The lab report was required to include a purpose, procedure, data/observations, all reactions and side reactions written out with qualitative data beneath each product and reactant except H2O, and a summary. The procedure involved measuring about a leg […]

Optical isomers, or moisteners, have the same sequence of atoms and bonds but are different in their AD shape. Two moisteners are non mirror images of one another (I. E. , choral), with the most common example being our hands. Our left hand is a mirror image of our right, yet there is no way […]
