Evolution of ammonia is one process that can result in the transfer of nitrogen from an aqueous system to the atmosphere. Discuss environmental conditions what would favor such a process. Would you expect ammonia evolution to be significant: (a) in an acid bog; (b) in the oceans?
Identify the Qual I cation(s) that is (are) confirmed present in a test solution by the formation of a precipitate.
assume that ethanol c2h5oh of 160 gramsnbspnbsp at the temperature of 27 degrees celsius is added with ethanol of 280
ammonium nitrate decomposes explosively upon heating to form nirtogen gas oxygen gas and sterm. assume ideal behavior
Amount of H2O2 in 15.8 g of hair bleach was obtained by titration with a standard KMnO4 soln.
10 logarithmic scale of hydrogen ion concentration Be careful If pH = -log [H+ ], what does [H+ ] equal? If the pH of an aqueous solution is 3.50 at 25 C, what is the hydroxide ion concentration?
How much heat is produced in burning 5 mol of CH^4 under standard conditions if reactants and products are brought to 298 K and H20(l) is formed
required to heat 10.0 grams of silver (Ag) from 112 degrees Celsius to 275 degrees Celsius
A particular natural gas exists, in mole percents, of 83.0% CH4, 11.2% C2H6, and 5.8% C3H8. A 380 L sample of this gas measured at 22.2 degrees Celsius and 745 mm Hg, is burned at constant pressure in an excess of oxygen gas.
Boron has only two naturally occurring isotopes. The mass of boron-10 is 10.01294 amu and the mass of boron-11 is 11.00931 amu. Calculate the relative abundances of the two isotopes.
Consider the titration of 30.0 of 0.035 with 0.030 . Calculate the after the following volumes of titrant have been added.
A solution is prepared by mixing 87.0 mL of 5.00 M HCl and 36.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+ ], [OH - ], and the pH for this solution.
