how 'bout just using some soap, or detergent?

You won't heighten at the age of 21. Sports/physical activity of any sort facilitate growth, particulary of growth of the leg bone's due to androgenic factors...as far as I know, you will not get taller at you current age. How tall are you exactly?

Energy itself is a state function if it the situation is conservative, such as with gravity and electric fields. Enthalpy itself relates to the chemical energy released/absorbed in an open system. The q relates to the temperature change (internal energy) while w relates to the work in expanding against the surroundings. It is simply a statement relating to the conservation of energy. I don't know why you're so confused with this. By the way q is a state function, it relates to the initial and final temperature, the w is a general expression for the energy lost in expansion.

Yep.

The a in the subscript of Ka indicates acid.

Calcium hydroxide as well as other ionic compounds dissolve to a certain extent in water , the degree to which it dissolves is given by the solubility constant, which indicates its saturation point. The solubility of calcium hydroxide increases in acidic solutions, particularly because one of its electrolyte components is hydroxide which will react with the strongest acid in the mixture. The solution once again becomes unsaturated and more calcium hydroxide solid will dissolve. Now what happens when you have enough acid in the solution? Figure it out.

You've got a reaction between a strong base and strong acid, the product salt will be weak with respect to its influence on pH, insignificant. At equivalence point, pH is 7. Depending on your desired pH add excess of one or the other. Calcium hydroxide will dissolve in acidic solutions (common ion effect).

Read up on the transition metals section of a standard principles of chemistry text. I believe that you are right in saying so that it has to do with crystal field splitting.

I would search for common particular experiments rather than try to create one on my own, such experiments have more than enough complications to them. I don't know of any experiments at this point.

The acid is a catalyst, you should know how this applies to your question. sidetrack- Also, in aqueous solutions, increasing the concentration of the acid does not necessarily increase the acidity of the solution. Acids dissociate through there interactions with water, in most cases we are assuming that water is plentiful. However, when water is limiting, you can guess that there will be problems with dissociation.

Simply the polar protic solvent, you should serach this term in the index of your org. chem text.

1. Water is a polar molecule due to its overall geometrical allignment of its dipole moments (referring to the character of electron sharing between to atoms-dipole moments). Hydrogen bonding exist due to significant electronegativity differences between two atoms and thus a strong dipole moment. However, since the oxygen possess lone pairs, it can intermolecular hydrogen in addition to intramolecular. 2. browse through the index for cohesivity or surface tension. 3. I'm not quite sure about this one, however, it pertains to the different density between ice and liquid h20 perhaps. Ice has a smaller density, which is opposite of the trend between other liquids and solids. 2.

An ionic bond typically relates to bonding in which electrons are more or less, not shared...in any ionic bond, the cation typically decreases to a smaller radii as the anion conversely increases in size. The ionic bond moreover relates to a subject which one might have studied in physics...attraction vs. repulsion (same charges repel, opposite charges attract).

In other words Grinard reagents are NOT stable. One cannot analysize a molecular by itself rather with the contexts...the molecules enviroment.

I recommend, Chemistry by Raymond Chang...any of the editions. Search for it on ebay, I bought mine for seven dollars.
