Given the balanced equation below. Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g) ΔHorxn= −23.0 kJ Compound ΔHof (kJ/mol) at 298 K CO −110.5 CO2 −393.5 Determine whether each statement is true or false using the provided drop-down menus. 1) The standard enthalpy of formation for Fe2O3 is −826 kJ. 2) If 1.2 moles of Fe2O3 react, the energy change of the reaction (qrxn) is −23.0 kJ. 3) The reaction releases energy to the surroundings.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
