I don't know either, because that's just a bunch of numbers. In chemistry you have be careful about writing out exactly what you're doing, and few problems won't benefit from explicitly writing out a chemical reaction formula. This is especially the case if you're trying to get someone...

You can calculate the enthalpy change from the reaction scheme or by using the enthalpy formula. If you select the former: Look at the reaction scheme that appeared at the top of the calculator. Do you need an additional reactant/product (C or F)? If so, enter the values of the ...
If we have the enthalpy values for the formation of reactants and products, we can calculate the enthalpy change for the reaction using the formula:ΔHR=ΣΔHf(products)−ΣΔHf(reactants)where ΔHf is the standard enthalpy of formation. Step 6: ConclusionThus, Hess's Law is applicable...

of the pressure of the given thermodynamic system. It represents the state of the system. It is not a measure of heat transfer. In short, enthalpy is used to measure the energy of the system. Enthalpy is expressed by the letter “H”. Thus, the formula to calculate enthalpy is given ...
there is a change in its volume. The alternate solution is to carry out the reaction at a constant pressure – in flasks and test tubes. Hence, there is a need for another state function which defines the change in internal energy at a constant pressure. The concept of enthalpy comes into...
