(a) Interpretation Introduction To determine: The standard enthalpy change of the given reaction. Explanation Given The balanced chemical equation for the given reaction is, Mg ( s ) + 2 H 2 O ( l ) → Mg ( OH ) 2 ( s ) + 2 H 2 ( g ) The enthalpy change of the given reaction is calculated by the formula, Δ H ∘ = ∑ n Δ H ∘ ( products ) − ∑ m Δ H ∘ ( reactants ) = ( Δ H Mg ( OH ) 2 ( s ) ∘ + 2 Δ H H 2 ( g ) ∘ ) − ( Δ H Mg ( s (b) Interpretation Introduction To determine: The mass of Mg in grams required to raise the temperature of given amount of water.

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 …

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 energ…
