Thermochemical equations

Thermochemical equations

Thermochemical equations. A typical chemical equation is S + O 2  SO 2 It is called a “thermochemical equation” when we add information about  H … S + O 2  SO 2  H = – 296.9 kJ If we change the equation, then the  H also changes … SO 2  S + O 2  H = + 296.9 kJ

Mole-Mass and Mole-Volume Relationships

Mole-Mass and Mole-Volume Relationships

Mole-Mass and Mole-Volume Relationships. The Mole-Mass Relationship. To convert the mass of a substance to the number of moles of the substance you have to use the molar mass of an element or compound. Mass = # of moles x (mass/1mole). The Mole-Mass Relationship.
