CH2 biradical?

Hi I was confused on a question on question 4 of the fall 2012 exam. One of the molecules it asked you to draw was CH2 and at the end it asked if any of the molecules you drew were radicals. I was wondering why CH2 would not be a biradical rather than have a lone pair. I tried drawing out the hybrid...

Re: Which flask represents the reaction in equilibrium?

I think it just asks you to pick when the flask first REACHES equilibrium, which would be flask 3!

Homework Problem Chapter 11 #25

For this problem, it asks for the equilibrium concentration of H2, given the equilibrium constant and that there is a "gas-phase equilibrium mixture of H2, I2, and HI at 500. K." How do we know if H2/I2 are the products or the reactants?

Sulfato

Is sulfato tridentate since it has a tetrahedral shape? Thanks!

Polydentates

Could someone clarify what makes a ligand a polydentate when looking at the lewis structure?

Re: Determining Bond Angles For Bent/Angular shapes

Yes, you can usually just say that the angle is "less than 120 degrees" because the VSEPR model can predict distortions qualitatively but not quantitatively, meaning the exact angle measurement is not guaranteed.

Chapter 3#59

In this question, it asked you to write the lewis structure of chlorine monoxide, ClO. The solutions manual indicated there was a single bond between Cl and O; however, shouldn't there be a double bond so that both Cl and O have formal charges of 0?

Question on G25

Practitioners of the branch of alternative medicine known as homeopathy claim that very dilute solutions of substances can have an effect. Is the claim plausible? To explore this question, suppose that you prepare a solution of a supposedly active substance, X, with a molarity of 0.10 mol x L(-1). T...
