Problem- A new potential heart medicine, code-named X-281, is being tested by a pharmaceutical company, Pharma-pill. As a research technician at Pharma-pill, you are told that X-281 is a monoprotic weak acid, but because of security concerns, the actual chemical formula must remain top secret. The company is interested in the drug's Ka value because only the dissociated form of the chemical is active in preventing cholesterol buildup in arteries.
To find the pKa of X-281, you prepare a 0.092M test solution of X-281. The pH of the solution is determined to be 3.00. What is the pKa of X-281?

Problem- A typical 100-watt light bulb consumes 100J of energy per second. If a light bulb converts all of this energy to 500nm light, how many photons are produced each second
how many milliliters of .1229 M NaOH are needed to completely neutralize 50.00mL of .1012M H2SO4 solution
You have a 10.40-g mixture of table sugar (C 12 H 22 O 11) and table salt (NaCl). When this mixture is dissolved in 150. g of water, the freezing point is found to be-2.24C. Calculate the percent by mass of sugar in the original mixture.
Compute the pH if NaOH solution of the 10.00 mL has been mixed. pKa of HCOOH = 3.74
Chloropropionic acid, ClCH2CH2COOH is a weak monoprotic acid with Ka = 7.94 x 10-5 M. Calculate the pH at the equivalence point in a titration 38.2 mL of 1.05 M chloropropionic acid with 0.90 M KOH
Consider the reaction given below. H2(g) + F2(g) 2 HF(g) (a) Using thermodynamic data from the course website, calculate G° at 298 K. kJ (b) Calculate G at 298 K if the reaction mixture consists of 7.3 atm of H2, 5.3 atm of F2, and 0.22 atm of HF.
