The change of enthalpy of a standard reaction can be determined using {eq}\Delta H^\circ_{rxn} = \sum n \Delta H^\circ_{products} - \sum n \Delta H^\circ_{reactants} {/eq}, where n is the number of moles. Remind that values of enthalpies for both reactants and ...
Condensed Formula: With the help of a condensed formula, it is easier to represent a group of atoms which are connected to a single atom in a given compound. More space is saved in condensed formula as compared to structural formula. ...
