oils and other nonpolar substances do not dissolve in water. At best, they congregate into large droplets. Soaps, however, are special molecules with a hydrophilic head and a hydrophobic tail, and they spontaneously organize into tiny spheres with hydrophobic interiors that can dissolve nonpolar com...
Which of these are compounds, and which are molecules? Explain. Answers: Salt (NaCl) contains two different elements, sodium and chloride, so it is a compound. Molecular hydrogen (H2) contains two atoms of the same element of hydrogen. Since H2 contains two or more elements, but the ...

Part A What are the subscripts in the empirical formula of this compound? The percent composition by mass of a compound is 76.0% C, 12.8% H, and 11.2% O. The molar mass of this compound is 284.5 g/mol. What is th...
a gaseous compound called butadiene, with a molecular weight of 54, combines nearly 4000 times and gives a polymer known as polybutadiene (a synthetic rubber) with about 200000 molecular weight. The low molecular weight compounds from which the polymers form are known as monomers. The picture ...
Small-molecule drugs are low-molecular-weight compounds, typically under 900 daltons, that can be chemically synthesized or derived from natural sources. Their simple, stable structures allow them to easily penetrate cell membranes and interact with specific biological targets, such as enzymes, receptors...
