Under certain nonstandard conditions, oxidation by O2 (9) of 1 mol of SO2(g) to SO3(g) absorbs 89.8 kJ. The heat of formation of SO3(g) is -204.1 kJ/mol under these Part A conditions. Find the enthalpy of formation of S02(g). Express your answer using one decimal place. ? ΔΗ kJ/mol

Consider the chemical reaction below: Zn + 2 HCI ZnCl2 + H2 where AHn -249270J Select the statement that are TRUE. O In order to produce 0.1 moles of hydrogen gas, 24927 J of heat must be released. O This is a reduction oxidation reaction. O This is a neutralization reaction. O 1 mol of HCI is associated with -124635J O This reaction is exothermic. O Heat will be considered as a reactant for this thermo-reaction. PrtScn F8 F3 F4 Home F5 F6 F7 F9 & 4. 5 7 8 %24

Classify the reaction endothermic or exothermic and give the change in enthalpy of the reaction. CH3OH (1) + 3 O₂ (g) → 2 CO₂ (g) + 4 H₂O (g) Δ Η = -557 kJ The heat energy in the reaction is Select an answer This makes the reaction Select an answer So, the energy would be on the Select an answer side.

Could someone please help! No plagiarism Please! 3. Draw an or find an image of an endothermic reaction or an exothermic reaction. Explain what makes it the type of reaction you chose to illustrate. Include arrows to show what direction the overall enthalpy of reaction (energy of reaction) flows.    4.  Ammonium nitrate dissolves in water via the following reaction: NH4NO3(s) → NH4+(aq) + NO3-(aq) The bond energies of the compounds in the reaction are as follows: NH4NO3 =   3040 kJ/mol NH4+ = 1564 kJ/mol NO3- = 1009 kJ/mol How much total energy does the reaction have, and how will the environment change when the reaction occurs?
