How is thermochemical equation different from a balanced chemical equation?
They specify heat flow for the reaction.
What is the reaction of sulfur with oxygen?
This is the balanced equation of the above reaction: S + O2 ---> SO2
What is the difference between a thermochemical equation and a traditional chemical equation?
Thermochemical equation includes enthalpy ( ΔH ) change in it.
What important information does a thermochemical equation have that a regular balanced equation does not?
A thermochemical equation shows the amount of heat given out or taken in when the reaction occurs. CH4 + 2O2 = CO2 +2H2O, deltaH = -890 kJ/mol Note delta H is negative when heat is given out, exothermic and +ve when endothermic. Sorry can't do delta symbol - its a triangle!
What is the balanced equation for FeS plus O2 equals SO2 plus FeO?
4FeS + 7O2 = 2Fe2O3 + 4SO2

What is the balanced equation for sulfur dioxide when added to a container of carnon dioxide?
CO2 + SO2 --> CO2 + SO2 There is no reaction.

What information is given in a thermochemical equation?
thermochemical equations show the accompanying heat of reaction at constant pressure
What is the balanced chemical formula for oxygen mixed with hydrogen sulfide?
The chemical equation is:H2S + O2 = SO2 + H2O
What is the balanced equation for FeS plus O2 equals SO2 plus FeO?
4FeS + 7O2 = 2Fe2O3 + 4SO2
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.

What is the balanced equation for sulfur dioxide and water vapor?
Equation SO2 + H2O ----> H2SO3 (Sulfurous acid) Having water as vapour does not change the formula in anyway so keep it simple
