Calculate the standard cell potential at 25 C for the reaction X(s)+2Y+(aq)?X2+(aq)+2Y(s) where ?H? = -651kJ and S = -371J/K.
Which of these products is formed under what is known as thermodynamic control, and explain mechanistically why this product predominates under thermodynamic conditions.
20.00 mL of 0.160 M HC2H3O2 (Ka = 1.8x10-5) is titrated with 0.200 M NaOH. What is the pH of the solution before the titration begins
Calculate the mass(in grams) of solids you must measure out to prepare 100 mL each of 0.025 M CuSO4, 0.025 M Ca(NO3)2, 0.025 M Al(NO3)3, and 0.025 M KCl.
KHP is an acid that is monoprotic and hardly hygroscopic. When carbon dioxide reacts with NaOH it produces sodium carbonate. I kind of understand how to do part b but i really don't understand how to do part a.

Type your question hereA 0.1390-g rock sample of unknown concentration was dissolved in HCl and diluted to 100.0 mL. Aliquots of 10.00 mL of this unknown solution were added to different volumes
I understand the rules for significant figures with multiplication/division, and adding/subtracting. But I am unsure of what to do when there is both multiplication and/or division, and adding and/or subtracting in the same question?
derive the clayperon equation. what is the primary use in phase diagrams? can you use it to justify the relative slopes
when 1 mole of N2 is isothermally compressed from 1 atm to 1000 atm at 0C. Find the fugacity coefficient of N2 at 0C and 1000atm. HINT: Recall that for a pure material, the chemical potential is just the molar gibbs free energy.
