The following are equations of interest in a laboratory similar to your current exercise. Your goal is to find the enthalpy change (deltaH) for reaction 1. Mg(s) + 1/2O2(g) --> MgO(s) deltaH1 = ? Mg(s) + 2H+(aq) --> Mg2+(aq) + H2(g) deltaH2 = +10.1 kJ/mol MgO(s) + 2H+(aq) --> Mg2+(aq) + H2O(l) deltaH3 = -5.0 kJ/mol 1/2O2(g) + H2(g) --> H2O(l) deltaH4 = -286.0 KJ/mol To arrive at equation 1 from the others... match the following equations with what you would need to do in order to add up properly to equation 1. You will also be asked to calculate the deltaH1 in an upcoming question. (hint: write it out on scrap paper, signs change if an equation is reversed.)

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
Question
100%
The following are equations of interest in a laboratory similar to your current exercise. Your goal is to find the enthalpy change (deltaH) for reaction 1.
Mg(s) + 1/2O2(g) --> MgO(s) deltaH1 = ?
Mg(s) + 2H+(aq) --> Mg2+(aq) + H2(g) deltaH2 = +10.1 kJ/mol
MgO(s) + 2H+(aq) --> Mg2+(aq) + H2O(l) deltaH3 = -5.0 kJ/mol
1/2O2(g) + H2(g) --> H2O(l) deltaH4 = -286.0 KJ/mol
To arrive at equation 1 from the others... match the following equations with what you would need to do in order to add up properly to equation 1. You will also be asked to calculate the deltaH1 in an upcoming question. (hint: write it out on scrap paper, signs change if an equation is reversed.)
