Which numerical setup can be used to calculate the heat energy required to completely melt 100. grams of h2o(s) at 0°c?
1.(100. g)(334 j/g)

increased stability in the completion of fluorine's outer shell.

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
