A) January 18‚ 2011B) Empirical Formula C) The purpose is to determine the empirical formula of a metallic oxide. D) Pre Lab Questions: After heating the metal‚ the crucible and contents should mass less than it did before it was heated. This is because heating the crucible may rid of other residue that was left in it; bringing it a to a constant mass. A yellow flame will deposit soot on the crucible. This would be a problem because the soot left on the crucible would vary from our constant

Antibodies to prevent illness‚ decreased chance of health problems‚ bonding time for the mom and baby‚ and reduce risk for breast cancer in mom. Breast feeding is free. No mothers should ever feel ashamed for formula feeding their baby. It may be impossible due to work or lack of breast milk. There would be

The research proposed suggest that breast-fed babies are more intelligent than formula-fed babies. The independent variable is if a child was breast-fed or not. The dependent variable is the child’s IQ based on the Wechsler Adult Intelligence Scale (WAIS). Other important concepts to be understood is that this was a study and not an experiment‚ so the data could be skewed because it is based on the mothers self-reports of how much the child was breast-fed at the one-year examination.

Introduction The following report shows that the proposal of the modernisation project should obtain funding from the corporate headquarters of Victoria Chemicals. The project has an initial outlay of GBP12 million to renovate and rationalise the polypropylene production line at Merseyside plant. This is done in order to make up for deferred maintenance and exploit opportunities to achieve increased efficiency. This report will look at the following four main areas of concern in order

the rate of decomposition of hydrogen peroxide.” Chemical equilibrium is the state of constant composition attained when opposing reaction rates become equal. There is an essential relationship between reaction rates and chemical equilibrium‚ one that we can describe quantitatively. At first thought‚ the connection may seem obscure - do we not need to be far from equilibrium to properly measure reaction rates? The dynamic nature of chemical equilibrium means that both forward and reverse reactions
