... There are about 100 different elements. Elements are shown in the periodic table. Compounds are formed from elements by chemical reactions. Compounds contain two or more elements chemically combined in fixed proportions and can be represented by formulae using the symbols of the atoms from which the ...

... Knowing the equilibrium constant allows us to predict several important features of the reaction. 1) the tendency of the reaction to ___________ (but not the _______________) 2) whether a given set of concentrations represent an __________________ condition 3) the equilibrium position that will be ...

... If both sides have equal # of moles of gas a shift in either direction will not reduce the pressure. So a increase in pressure has no effect on the equilibrium situation. So an equilibrium reaction that has the same number of moles of gas on both sides of the equation will not be affected by the cha ...

... CONCLUSIONS and PERSPECTIVES The peptide bond type of linkage is more common than originally thought. The simplest molecule containing this bond, H2N-CH=O is more stable than any of its isomers. This result is confirmed on N-methyl acetamide. Neutral Glycine and -Alanine are not the most stable co ...

Unit 8 Student Notes
... Ions in solution are in constant motion and therefore are constantly colliding with other particles (other ions or solvent particles). If an ion of calcium (Ca2+) collides with the surface of a salt crystal, it may lose its surrounding shell of water molecules and join the crystal structure. If this ...

... Scientists discovered that by simply determining the mass of the substance, it was possible to count particles or atoms. A mole (mol) is the amount of a pure substance that contains the same amount of chemical units as there are atoms in exactly 12 grams of carbon, namely 12. In order to avoid confu ...
