The attractions between atoms within a molecule of NH3 are best characterized as A. hydrogen bonds B. ionic bonds C. polar covalent bonds D. London (dispersion) forces E. ion-dipole forces Correct Answer-polar covalent bonds R(g) + 2T(g) ⇌ 2X(g) + Z(g) The reaction mixture above is at equilibrium at 298 K. The value of the equilibrium constant for the reaction is 16 at 298K. If R(g) , X(g) and Z(g) each have an equilibrium concentration of 2.0 M, what is the equilibrium concentrati...

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

MetabolismAnabolism+catabolism. the chemical processes that occur within a living organism in order to maintain life. Enzymatic Reactions inside a living organism CarbonCarbon is an element with the atomic number 6, meaning it has four electrons in its outer shell. These electrons can form covalent bonds with carbon atoms or atoms of other elements. This allows a diversity of stable compounds to exist. LipidsA diverse group of Carbon containing macromolecules made up of carbon, hydroge...
