Water is a unique substance. It expands when it freezes, it takes a lot of energy to raise its temperature, and it dissolves many things. These characteristics all stem from the geometric shape of water. Answer and Explanation: Water molecules are attracted to each other because opposite sides...
Nonpolar molecules, like fats and oils, don't interact with water or form hydration shells. These molecules don't have regions of partial positive or partial negative charge, so they aren't electrostatically attracted to water molecules.
Two water molecules are weakly attracted to each other when a slightly positive hydrogen atom in the first molecule is attracted to the slightly negative oxygen atom on the second molecule. What type of bond is this? A)Ionic B)Polar covalent C)Nonpolar co ...
Which of the following molecules is NOT a steroid? A) testosterone B) estrogen C) glycerol D) cholesterol E) vitamin D All proteins: a) are enzymes b) contain at least one alpha-helix c) are water-soluble d) a and b above e) bind to other molecules W...
in water. This insolubility is often referred to as hydrophobic, or "water-fearing." However, this term may be misleading as their insolubility in water is due to the water molecule's much greater affinity for other water molecules than a repulsion between the lipid and water molecules. ...
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that includemostly nonpolar carbon–carbon or carbon–hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. ...
Individual bonds can be polar or nonpolar, as can entire molecules. Polar means there is unequal sharing of electrons, while nonpolar means equal sharing.What Is a Polar Covalent Bond? The periodic table is divided into two main sections, metals and non-metals. When two non-metals form a ...
This means they do not mix well with water. 2. Definition of Solubility: Solubility refers to the ability of a substance to dissolve in a solvent. In this case, we are examining the solubility of lipids in water. 3. Properties of Lipids: Lipids are generally nonpolar molecules, which ...
end of other molecules, like a magnet. This attraction forms hydrogen bonds. Polar molecules are also known as hydrophilic (water-loving) or water-soluble molecules. However, water does not dissolve nonpolar or hydrophobic (water fearing) molecules well. Hydrophobic molecules include oils and fats....
Alumina-rich zeolites are attracted to polar molecules such as water, while silica-rich zeolites work better with nonpolar molecules.Photo: Synthetic zeolite crystals grown at CAMMP (Center for Advanced Microgravity Materials Processing), a NASA-sponsored Research Partnership Center. The ones on the ...
