BPA is used as a raw material in manufacturing polycarbonates and epoxy compounds. Polycarbonate plastic is a lightweight‚ high-quality plastic that has a unique balance of toughness‚ optical clarity‚ high heat resistance‚ and excellent electrical resistance. As a result of these traits‚ polycarbonate is used in an array of common

REVIEW 1. (L.O. 1) Chapter 6 discusses the essentials of compound interest‚ annuities and present value. These techniques are being used in many areas of financial reporting where the relative values of cash inflows and outflows are measured and analyzed. The material presented in Chapter 6 will provide a sufficient background for application of these techniques to topics presented in subsequent chapters. 2. Compound interest‚ annuity‚ and present value techniques can be applied to

It can also pertain to a class of chemical compounds that formerly comprised only those existing in or derived from plants or animals‚ but that now include all other compounds of carbon. This is the first thing that we need to understand. The fact that organic compounds contain carbon and are also combined with nitrogen‚ bromine‚ hydrogen. Sulfur‚ and chlorine and that the majority of the compounds found and tested in crime scene labs are going to be organic. The organic

A mixture has a variable composition therefore there is not ONE formula for it. Slide 7 and 9: What are the differences in elements and compounds? An element has the same kind of atoms‚ like carbon‚ oxygen‚ and hydrogen. Atoms of the same type are classified as elements. Whereas a compound is a chemical combination of elements‚ that may form molecules or crystals. A compound can be chemically broken down into simpler parts. ● Slide 10: What are the 2 major types of mixtures and how are they different from

Use of Formalin and Other Additives in Foods Formalin is chemical compound that usually people used for durable human and animals corps. Nowadays‚ many people use it for durable foods‚ such as tofu and terasi. The use of formalin and other dangerous preservatives in foods has been a serious problem for three reasons. Firstly‚ formalin is not for human beings‚ but it is for biological specimen and experiments. It is not for food preservative. Of course when it is used for food preservative‚ it

the second part is to determine the unknown substance‚ by comparing its melting point with two known samples and its melting points. In both cases‚ the melting points of the substances will be used to determining the eutectic point and the unknown compound. Abstract: The purpose of this experiment was to determine the eutectic point for the naphthalene biphenyl mixture‚ as well as determining the melting point of an unknown substance by comparing it with two known samples. We will be constructing
