Given the following reactions and their enthalpy changes,

cis C4H8(g) +6 O2(g) → 4 CO2(g) + 4 H2O(g) ΔH = 2710 kJ

trans C4H8(g) +6 O2(g) → 4 CO2(g) + 4 H2O(g) ΔH = 2707 kJ

what is the enthalpy change for the reaction

cis C4H8(g) → trans C4H8(g)?

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

is there any options? maybe im just not seeing them but i need the options to
