Lab of Determining an Empirical Formula B2 Honors 12/18/13 Abstract In this lab‚ to help better understand the concepts of gram atomic masses and empirical formulas‚ we found the gram atomic masses and empirical formula of a binary compound. The two compounds should form a definite whole number ratio by mass. This ratio will also help determine the subscripts of the elements in the empirical formula. Errors in this experiment can stem from measuring wrong or doing equations incorrectly.

Chebyshev’s Theorem and The Empirical Rule Suppose we ask 1000 people what their age is. If this is a representative sample then there will be very few people of 1-2 years old just as there will not be many 95 year olds. Most will have an age somewhere in their 30’s or 40’s. A list of the number of people of a certain age may look like this: |Age |Number of people | |0 |1 | |1 |2 | |2 |3

Empirical Evidence The study of addiction has included alcoholism and drug addiction for a long time. The recent obesity epidemic has brought food addiction as a serious concern even though it is still a controversial issue. It is difficult to accept the idea of food being an addiction. Addiction has been defined as” a primary‚ chronic disease involving brain reward‚ motivation‚ memory and related circuitry.”(Whitepaper) There are numerous studies and research that support the fact that over

As we learned before on how to determine the empirical formula of a compound based on the test and also chemical analysis on it. Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this experiment. RESEARCH QUESTION: How empirical formula of Magnesium Oxide is obtained by heating

interpolator that has a minimum error variance.(Hung‚ 2001) Empirical Bayesian Kriging is a Kriging-based interpolation method that accounts for uncertainty in semivariogram estimation by simulating many semivariograms from the input data. In addition‚ Empirical Bayesian Kriging can account for moderate nonstationarity by building local models on subsets of the input data. Semi variance modeling was carried out to create the probability map. Empirical Kriging regression assumes that‚ the deterministic component
