How is thermochemical equation different from a balanced chemical equation?
A thermochemical equation includes information about the energy changes associated with a chemical reaction, such as enthalpy changes. A balanced chemical equation shows the reactants and products involved in a chemical reaction in their correct proportions. While a balanced chemical equation gives the stoichiometry of the reaction, a thermochemical equation provides additional information about the heat flow during the reaction.
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is always given in units of energy, typically kilojoules (kJ) or kilocalories (kcal), and can be either exothermic (releasing heat) or endothermic (absorbing heat).
What type of reaction is shown in this thermochemical equation A plus B plus Heat -- C plus D?
The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
What is the balanced thermochemical equation for SO2?
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
A shorthand description of a chemical reaction using chemical formulas and symbols is a chemical what?
A chemical equation is a shorthand description of a chemical reaction.

What information is given in a thermochemical equation?
thermochemical equations show the accompanying heat of reaction at constant pressure
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

The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
What is the thermochemical equation for endothermic changes?
A + B + Heat → C, ΔH > 0
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
What is the thermochemical equation for the formation of 1.00 mol of liquid water?
The formation of 1.00 mol of liquid water can be represented by the chemical equation: 2H2(g) + O2(g) -> 2H2O(l), where 234 kJ of heat energy is released.
What is the balanced thermochemical equation for SO2?
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
What is thermochemical equation for combustion of cyclohexane?
The thermochemical equation for the combustion of cyclohexane (C6H12) is: C6H12(l) + 9 O2(g) -> 6 CO2(g) + 6 H2O(g) This reaction is exothermic, meaning it releases energy in the form of heat. The standard enthalpy of combustion for cyclohexane is -3925 kJ/mol.
What important information does thermochemical equation have that a regular balanced equations 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!
