1problem left in homework: a chemist titrates 240 ml of a 0.693 m ammonia solution with 0.6068 m hcl at 25° celcius.

calculate the ph at equivalence the pkb of ammonia is 4.75. round to two decimals. (you may assume that the total volume equals initial volume plus the change your volume)

Select the correct answer. given: 2libr + ba → babr2 + 2li in this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced? a. 1.18 mol b. 2.37 mol c. 4.73 mol d. 16.4 mol e. 32.9 mol

Based on the equation and the information in the table, what is the enthalpy of the reaction?
