You need to calculate the enthalpy change (AHO) of the reaction A+B → C. How can the enthalpies given for the reaction steps below be combined to
give the overall change in enthalpy?
2A+BD
C+AD
AH2
O A. AH AH , +AH2
O B. AHO E AH, AH2
C. AH = AH - AH2
O D. AHORAH 2-AH

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
