We want the reaction 188o + 11h --> 189f + 10h. what is the q-value of this reaction? is it endo- or exo-thermic? (m180=17.999161 u, mh=1.008665 u, mh=1.007825 u, m18f=18.000938 u ; all atomic masses, except neutron)
give mev.
do 10mev protons provide enough energy to drive this reaction?

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
