Please help! Show work if possible. Thank you You find a 3100-mg copper penny (circa 1976) in the snow. How much heat is absorbed by the penny as it warms from the temperature of the snow, which is -8.0 degrees Celsius, to the temperature of your body, 37 degrees Celsius? Assume the penny is pure copper. Specific heat of pure copper is 0.385 J/gC

the answer would be a

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.
