Is there any way (ex. MO theory, valence electrons, etc) to determine the coordination number of a metal ion with another ion? I know it is generally a multiple of the oxidation number of the metal ion. However, for something like Ni and NH3. how would I know that it's a coordination number of 6?

Yes, this is exactly the explanation I found elsewhere! Thank you so much, Borek!

The initial temperature is 24 degrees Celsius and the final temperature is 29 degrees Celsius. However, 5 degrees Celsius as a delta T is not an option given :/

Homework Statement See Thumbnail. Homework Equations N/A The Attempt at a Solution I am absolutely floored as how to do this problem.

Thank you so much!

Would it be 1? I feel like I'm missing something obvious o_O

Homework Statement The reduction of O2 to H2O in acidic solution has a standard reduction potential of +1.23 V. What is the effect on the half-cell potential at 25 °C when the pH of the solution is increased by one unit? O2(g) + 4H+(aq) + 4e- –> 2 H2O(l) (A) The half-cell potential...

Is there any way you could manipulate the given rate to fit the rate law?

Homework Statement http://i.imgur.com/Ypqcw19.png Homework Equations N/A The Attempt at a Solution Since the reaction involves the breaking of bonds in MCO3, I assume we are looking at coulomb interactions. I'd think the answer is D) BaCO3 because all the options have a 2+ charge, but barium...

Homework Statement Internal Energy Change Homework Equations N/A The Attempt at a Solution If internal energy change equals enthalpy change, then I am looking for the reaction which has the enthalpy change closest to zero. I know it cannot be A, as the formation of water is highly exothermic...

Received my book yesterday.

Again, sorry for being late to reply, but thanks. I guess I'll just have to memorize some of the common elements's atomic radii ?:)

Sorry for the extremely late reply. But thanks, that makes so much more sense!

Can I claim the Illusion of Conscious Will? I'll PM you my mailing address!

It's the wrong answer :oops:
