How do you find delta h of a chemical equation? Socratic
WebMay 17, 2024 · ΔH diss = − qsolution The minus sign is used here because heat lost carries a negative sign. To find the heat absorbed by the solution, you can use the equation q = m⋅ c ⋅ ΔT −−−−−−−−−−−−− Here q is the heat gained by the water m is the mass of the water c is the specific heat of water WebBy combining the bond enthalpy values for all of the bonds broken and formed during a reaction, it's possible to estimate the total change in potential energy of the system, which is Δ H rxn \Delta\text H_{\text{rxn}} … by88666
