Across
3.an ammonia molecule in which one or more H atoms are substituted by alkyl or aromatic groups
5.a quantum of light evergy
8.a molecule of large molar mass that consists of many repeating subunits called monomers
10.a process in which electrons are gained; a decrease in oxidation number
14.a polysaccharide of glucose; produced by animals for energy storage
15.the concentration of a saturated solution of a solute in a particular solvent at a particular temperature; solubility is a specific maximum concentration
16.a neutral subatomic particle present in the nucleus of atoms
17.a group of two or more electric cells connected in series
22.an organic compound characterized by the presence of a hydroxyl functional group;
23.the technological process of measuring energy changes in a chemical system
26.the process of dissolving
28.the electrode where reduction occurs
31.a reaction in which an ester is hydrolyzed
32.an ester of three fatty acids and a glycerol molecule
Down
1.amount of energy transferred between substances
2.a mixture of a conjugate acid-base pair that maintains a nearly constant pH when diluted or when a strong acid or base is added; an equal mixture of a weak acid and its conjugate base
4.a compound with the same molecular formula as another compound, but a different molecular structure
6.a region of space around the nucleus where an electron is likely to be found
7.absorbing thermal energy as heat flows into the system
9.a molecule of relatively low molar mass that is linked with other similar molecules to form a polymer
11.an organic compound characterized by the presence of a carbonyl group bonded to two carbon atoms
12.a solid electrical conductor
13.a process in which electrons are lost; an increase in oxidation number
15.orbitals of different shapes and energies, asd given by the secondary quantum number,l; the subshells are most often referred to as s,p,d, and f.

21.able to exist in two forms that are mirror images of each other
24.a polysaccharide of glucose; produced by plants for energy storage
25.the point in a titration at which a sharp change in a measurable and characteristic property occurs
27.a small discrete, indivisible quantity; a quantum of light energy is called a photon
29.the solution being analyzed in a titration
30.a molecule made up of two monomers
