Enough of a monoprotic acid is dissolved in water to produce a 0.0170 M solution. The pH of the resulting solution is 6.34. Calculate the Ka for the acid.
Hydrogen was cooled from 150 c to 50 c. It's new volume is 75 ml. What was the original volume?
What are the active ingredients & determine what possible tests to perform to identify each active ingredient. (what is the expected result?) - can't use melting points, boiling points, burning of solids, benedict's solution and tasting.
Natural gas is a mixture of many substances, primarily CH4,C2H6,C3H8 and C4H10. Assuming that the total pressure of the gases is 1.34 atm and that their mole ratio is 94 : 4.0 : 1.5 : 0.50, calculate the partial pressure (in atmospheres) of each g..

When each of the following pairs of aqueous solutions is mixed, does a precipitation reaction occur? If so, write the formula and name of the precipitate. (Type "NONE" in the blanks if there is no precipitation reaction.)
What is the molarity of a HCl solution that contains 6.13 g of HCl in 352 mL of solution?
Acidic and basic solutions have distinct physical and chemical properties. For chemistry courses, especially those with a laboratory component, it is important that you be able to distinguish these properties
Producing ethanol as a biofuel from sugars in corn (glucose) has become a major industry in the grain belt. This process can be summarized as follows, where glucose to form ethanol and carbon dioxide. Use bond energies to estimate Delta E for this..
