Thermochemical equations are chemical equations that include the of the reaction.?
Termochemical reactions include the enthalpy of reactants and products.
What is thermochemical analysis?
This is the study of heat released/absorbed during chemical reactions.
What is the thermochemical equation for endothermic changes?
A + B + Heat → C, ΔH > 0
What is the thermochemical equation for the formation of 1.00 mol of liquid water?
H2 + 1/2o2 --> h2o
What is correct 4.184 or 4.1868 joules per gram for every change in temperature 1 degree centigrade specific heat of water?
In the steam table and thermochemical variations in the related link below. It may depend on which variation your meaning.
What information is given in a thermochemical equation?
thermochemical equations show the accompanying heat of reaction at constant pressure
How is thermochemical equation different from a balanced chemical equation?
They specify heat flow for the reaction.
Thermochemical equations are chemical equations that include the of the reaction.?
Termochemical reactions include the enthalpy of reactants and products.
What type of reaction is shown in this thermochemical equation A plus B plus Heat -- C plus D?
endothermic
Why it is necessary to mention physical states of reactants and products in thermochemical equation?
because energy produced by a therm chemical reaction depends upon physical state
What is the thermochemical equation for chlorine gas reacting with bromide (aq) to form bromine?
The chemical reaction is:Cl2 + 2 NaBr = 2 NaCl + Br2
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!

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.
Which of these could be considered a system under thermochemical study?
All of these
What is the sign convention used in thermochemical calculations?
Exothermic (negative) and endothermic (positive)
