Sulfur reacts with oxygen to form sulfur dioxide (SO2(g), Delta. Hf = –296.8 kJ/mol) according to the equation below.

Upper S (s) plus upper O subscript 2 (g) right arrow upper S upper o subscript 2 (g).

What is the enthalpy change for the reaction?
Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants..

–593.6 kJ
–296.8 kJ
296.8 kJ

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
