Hess's Law

When we are adding reactions in order to solve for the deltaH (using Hess's Law), are we supposed to flip the reactions in order to cross cancel?
If we are, is there a specific way to flip the reaction? or do we just flip them to our convenience?

Work Function/ Wavelength Q4

Question #4 (Fall 2010 Midterm) The work function for chromium metal is 4.37eV. What wavelength of radiation must be used to eject electrons with a velocity of 1.50*10^3 km*s^-1? I understand that we are looking for wavelength, but in the first step when solving, as done in the course reader it is m...
