This pattern of spots would not occur if you sent a flashlight beam through the mesh because light from the flashlight O is neither coherent nor monochromatic. O cannot be sent through a single opening of the mesh. O is horizontally polarized, while laser light is vertically polarized. O is vertically polarized, while laser light is horizontally polarized.

Sulfur exists in two allotropic forms - monoclinic and rhombic. Some heat-related data for these two allotropes are: S(rhombic) + O$_2$(g) $\rightarrow$ SO$_2$(g) $\Delta$H$_f$ = -296.06 kJ/mol S(monoclinic) + O$_2$(g) $\rightarrow$ SO$_2$(g) $\Delta$H$_f$ = -296.36 kJ/mol Using Hess' Law, determine the enthalpy change (in kJ/mol to one decimal place) for the transformation: S(monoclinic) $\rightarrow$ S(rhombic) Whether it is positive or negative matters. Do not enter units.
