The letter in chemistry that represents heat is the letter Q. Q is the heat of the reaction that has occurred.
· The letter H is the symbol for Hydrogen
There is no symbol that will show weather or not heat is needed in a decomposition reaction.

Co2 (g)+C(s)--->2CO(g)
Specific heat capacity is the amount of energy or heat (q) required to raise the temperature of 1 gram of substance 1 degree Celsius. from the equation q = mc(Tf-Ti) q = energy / heat and is in joules (J) m = mass of in grams (look at periodic table for mass (g) per 1 mole of element) c = specific heat, for example water is 4.184 J/g*C Tf = Final temperature in *C Ti = Initial Temperature in *C
The reaction is:CaCO3------------CaO + CO2
The symbol of heat is Q.
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
it means heat.
change in heat....
it means heat.
Silver (Symbol Ag).
standard heat of formation in a compound.
Press alt and 3 well it works for me
W is the symbol of watt, of wolfram etc.

Heat added to catalyze a chemical reaction is represented by the Greek letter delta above the yield arrow.
enthalpy, H
