LeChatelier's Principle: A change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner as to reduce or counteract the change. Factors that determine the equilibrium conditions of a sy

Even though I was trying very hard to get around it because it destroys the point of absorption spectrums, stick with the approximation made on Friday. Now, in your lab reports, I hope you can write about how you would improve the lab so we don't hav
TITRATION: WEAK BASE + STRONG ACID 29.0 mL sample of 0.237 M trimethylamine, (CH3)3N, is titrated with 0.350 M perchloric acid. After adding 31.2 mL of perchloric acid, the pH is 1.17 Use the Tables link on the toolbar for any equilibrium constants that a
A 33.5 mL sample of a 0.495 M aqueous hypochlorous acid solution is titrated with a 0.370 M aqueous potassium hydroxide solution. What is the pH after 26.9 mL of base have been added? pH = 7.63 Feedback: Please note that while the results of the
Rearrange the equation above to solve for ln Keq: lnK = - ( Go) RT = - (83600)J mol mol K 8.314 J 1 298.15K = -33.726
Note that all of the units cancel as they should to take the logarithm.
Raise to the base "e" to clear the logarithm: K = e-33.726 = 2.25

WRONG ANSWERS When carbon (C) reacts with oxygen (O2) two substances can form carbon dioxide (CO2) or carbon monoxide (CO). The heat of formation of CO is 110 kJ/mol and the heat of formation of CO2, 394 kJ/mol. C (s) + O2 (g) -> CO (g) delta Hf (CO) = 11
