Given the data below, what is the standard free energy for the reaction B2H6(g) + 3Cl2(g) = 2BCl3(g) + 3H2(g) in kJ/mol? While exact sig figs are not required, please be careful with them: the answer is accurate to the tenths place. Answer in kJ/mol. Do not use scientific notation. Do not type units. Standard Free Energy of Formation Compound

cumulative The pKa of 2-methylpyridine (H7C6N) is 5.95. What is the pH of the buffer made from 0.41 mol 2-methylpyridine and 0.93 mol sodium 2-methylpyridinium (the conjugate acid of 2-methylpyridine) dissolved to make a 500.00 mL solution? Exact sig figs required. Do not use scientific notation.

A system initially has 24 states. Select all the final state values that will result in a non-spontaneous reaction. You may select more than one. The instructor suggests you try out each in your calculator.
