1 Determination of Empirical Formula: Preparation of a Copper Sulphide. Aim The aim of the experiment was to determine the empirical formula of sulphide of copper and to make sure that an amount of copper metal reacted with elemental sulphur‚ Eq. 1. To be able to calculate the empirical formula of copper sulphide‚ the mass (grams) of copper has to be known and the mass (grams) of copper sulphide after the reaction. Copper‚ chemical formula Cu‚ is a known metal with a red-brown

Copper has been used in cookware because of its good thermal conductivity. In Eastern and Western cooking traditions‚ copper cookware sets were popular because they provided the best conductivity‚ and therefore the most even heating and cooking. Copper pots and pans were a staple of the colonial kitchen and have withstood the test of time to remain popular in the professional and home kitchen alike. Copper cookware sets will typically include a saut� pan‚ frying pan and a sauce pan. These are essential

Qualitative Versus Quantitative Research There has been a large amount of complex discussion and argument surrounding the topic of research methodology and the theory of how studies should push forward. Majority of this debate has centered on the issue of qualitative versus quantitative study. Different methods become popular at different social‚ political‚ historical and cultural times in our development‚ and‚ both methods have their strengths and weaknesses. The researcher and/or the culture

What according to you is a BPO? BPO stands for Business Process Outsourcing. When a company decides to outsource some of its non-core work processes to another company with expertise in it‚ it is called Business Process Outsourcing. What are the different types of BPOs? BPOs can majorly be divided into following categories based on the jobs they perform: a.) Administrative Department b.) Purchase Department c.) Selling Department d.) Call Centre e.) Back Office Why do companies outsource

Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser

Quantitative & Qualitative Research COMPARISON OF QUANTITATIVE AND QUALITATIVE RESEARCH METHODS Introduction This paper compares and contrasts qualitative and quantitative research methods in three basic areas. These are the of their: epistemological foundations‚ data collection methods‚ and data analysis methods. The paper ends with a brief summary of the primary points made. Comparison Gall‚ Borg and Gall (1996) discuss several similarities and differences between qualitative and

Quant Formula Study Guide MISCELLANEOUS‚ COMMONLY USED FORMULAS Finite population correction factor: Multiply SE of sample mean by fpc to make the correction ------------------------------------------------- Independent samples of same population with same standard deviation (variances are equal). Confidence interval: df for t-multiple is (df1 + df2)‚ or (n1 – 1) + (n2 - 1) Pooled estimate of common standard deviation: SE of difference between two sample means -------------------------------------------------

but focused samples are more often needed than large samples. In the conventional view‚ qualitative methods produce information only on the particular cases studied‚ and any more general conclusions are only propositions (informed assertions). Quantitative methods can then be used to seek empirical support for such research hypotheses. ------------------------------------------------- Why do we use qualitative research? Research is a seeking process which result is generalized in order to explain

3.7.2. Quantitative Data Analysis In this study‚ the quantitative data which was obtained through questionnaire which is used analyzed using descriptive statistics of central tendency measurements and percentages. The data was first coded‚ organized and discussed using mean‚ mode‚ frequency and median. The median will be used to show the central tendency for the ordinal scales and skewness to show the distribution of the population. In addition‚ percentages will be used for the nominal scale especially
