where C is carbon, H is hydrogen, O is oxygen and each hyphen is a chemical bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. The OH (O - H) group on the molecule is what makes it an alcohol. There are four types...
Spring water: Spring water comes from a protected, underground water source from which the water flows to the surface on its own. It may be collected either at the surface spring or through a sanitary, protected hole drilled directly into the source feeding the spring. If the water is collec...
Bacterial chemotaxis requires bidirectional flagellar rotation at different rates. Rotation is driven by a flagellar motor, which is a supercomplex containing multiple rings. Architectural uncertainty regarding the cytoplasmic C-ring, or ‘switch’, limi
The theory is that consuming large amounts of water or eating food will dilute the alcohol in the system, leading to a lower BAC reading. While staying hydrated and eating can affect how your body absorbs alcohol, they do not significantly change the alcohol concentration in your breath by th...
Which molecule allows the transport of charged substances across the plasma membrane? How are the proteins used for active transport different from those used for facilitated diffusion? How many cells does a fly have? The lipid bilayer molecules do what for the cell? How is the plasma membrane ...
A. solvent B. hydrophobic molecule C. solute D. nonpolar molecule What is the term used for substances that attract water molecules? 1. How do molecules of a polar compound differ from those of a nonpolar compound? 2. What happens when ionic compounds are mixed with water? 3. What is ...
Water. At its most basic, water is a molecule with one oxygen atom and two hydrogen atoms, bonded together by shared electrons. It is a V-shaped polar molecule, which means that it's charged positively near the hydrogen atoms and negatively near the oxygen atom. Water molecules are ...
Water is a great conductor, so it disperses a charge before it can build up [source: Krasicky]. A Game-Changer in Your Laundry Room If you'd rather wait until your clothes are completely dry, though, dryer sheets might be the way to go. Because static in the dryer is caused by ...
The equivalent unit was introduced to account for the fact that when solutes dissolve in solvent to create a solution, the number of particles dispersed depends on the valence of the solute. For example, when one molecule of KCl dissolves, it leaves two ions, or charged particles − a K+...
A molecule is polar if one part of it has a partial positive charge, and another part has a partial negative charge. In abond, atoms can either share electrons (covalent) or give them up (ionic). The atom that holds the electrons closer will thus be more negatively charged than the oth...
