Determine the oxidation number of the underlined element in the following compound. Be sure to indicate if the oxidation number is positive or negative. NaNO3

Look at the heating/cooling curve for water diagrammed below. Between which two letters is the phase changing of condensation taking place? Response should be in the form “x and y”. 

Balance the equation below by placing the correct coefficients in the blanks. Your response should list the coefficients in order from left to right, separated only by commas; no spaces. If no coefficient belongs in a blank, represent it with a “1”. For example the equation 2 H2O  → 2 H2+O2 would be represented as 2,2,1.  ____H3(PO4)  +  ____ Rb(OH)   →   ____H2O + ____Rb3 (PO4)

All of the following regarding Wernicke Encephalopathy are correct EXCEPT:

You have a 22 year old female patient with a two year history of recurrent, unilateral, pulsating headaches with vomiting and photophobia. The headaches, which generally last 3 hours can be aborted by resting in a dark room. Her physical examination is unremarkable. This representation is most consistent with:
