Made from plastic and glass, composite resin fillings are designed to match the color of teeth perfectly—a stark contrast to silver fillings (amalgams). But aesthetic appeal isn't the only benefit of choosing composite resin over its silver counterpart. Below are three reasons to have your cavities filled with composite resin. 1. Composite Resin Is Mercury-Free One of the biggest advantages of composite resin is the fact that it's mercury-free. Amalgams, on the other hand, contain large amounts

The SN2 reaction can be evaluated by first observing the chemical mechanisms of the compounds involved. The agents took into account for the mechanism was the naphtholate anion and allyl bromide. First, a pair of lone pairs on the oxygen anion on the naphtholate compound attacks a single-bonded carbon on the allyl bromide compound. Afterwards, the bromide leaving group exits the allyl bromide compound, and creates its own anion cloud. Overall, this synthesizes naphthyl ether. The mechanism cannot

1920s Research Paper The Prohibition Era is one of the many names for the 1920s because of the laws put into place at the time to prohibit making, selling, and transporting alcoholic beverages.

These generally Christian groups believed that America was becoming immoral and that morality would be improved if alcohol was not consumed. Rum runners became extremely prominent

Figure 7. Isocratic Elution w/ 40% H2O/60% methanol at 270 nm The peak identities were determined using the polarity of the molecules and their interactions with the silica beads in the channel. The silica beads were used as the stationary phase of the HPLC while a mixture of methanol and water was used for the mobile phase. Since the mobile phase mixture of methanol and water is polar and the silica beads are non-polar, the most polar molecule, which was determined to be m-cresol, spent the least

To begin with in Figure 1 and 2 you are shown the conductivity of certain concentrations and the water samples. In Figure 1, you can see that the distilled water was not able to conduct electricity, whereas the 500 ppm concentration had a kind of dim light. Out of all the concentrations the 500 ppm concentration conducted electricity the best. In Figure 2, samples 6152 and 1348 were not able to conduct electricity. On the other hand, when we compared the brightness of the light from samples 7709

The film prohibition directed by Ken Burns honestly depicted the important people that played a major role in the prohibition era, and the toll alcohol took on families. During this era alcohol was as American as apple pie, men who worked hard and all day would drink beer or whiskey during breakfast, lunch, and dinner.
