Polymers are molecules made from repeating units of identical organic compounds that are linked together by hydrogen bonds?
Is the following sentence true or false EPA water quality standards allow drinking water to contain only water molecules?
True or false a compound whose molecules contain one boron atom and three fluorine atoms would be named monoboron fluoride?
False. Atoms themselves only change during nuclear decay, fusion or fission. Outer electrons can be shared, donated or received during bonding but the atom doesn't change in and of itself. When matter changes state the bonds themselves are not affected. All that happens in a change of state is that molecules gain more kinetic energy. The bonds within the molecules are not altered.
Opiates are one of a general group of related organic molecules, many of which can actively be processed into specific opiates with the right knowledge. Opiate tests actually look for digestive products of opiates, not the drugs themselves. Many of the related molecules can cause the same reactions as these byproducts when tested, leading to a false positive for opiates. The best example is poppy seeds; these contain large enough amounts that consuming a sixpack…
