List the procedural steps, from start to finish, that are required to convert benzoic acid into methyl benzoate via a fischer esterification.

1) Dissolve the Benzoic Acid (C7H6O2) in Methanol in a round bottom   
     flask.2) Add Concentrated Sulfuric Acid (H2SO4) and heat under a reflux
     apparatus on a steam bath.3) Pour the reaction mix into ice, and rinse the reaction flask with
    dichloromethane (CH2Cl2).
4) Collect the combined layers in a test tube.5) Wash the dichloromethane layer with sodium carbonate
    (Na2CO3) solution, followed by a wash with sodium chloride
    (NaCl) solution.6) Dry the dichloromethane by distillation on a steam bath.
7) Distill the remaining liquid ester in a vial on a heating mantle.

Answer : option c) heat is released during the process.explanation :

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.

C) electrons encircling a nucleus with neutrons and protons
