mass defect
The difference in potential energy between the reactants and products.
The Hreaction is the difference between Hf, products and Hf, reactants
Reactants are what you start with, and products are what you end up with.
The change in entropy between products and reactants in a reaction
The reactants are compounds that react to form new compounds (the products). apex
The difference in potential energy between the reactants and products.
The Hreaction is the difference between Hf, products and Hf, reactants
Reactants are what you start with, and products are what you end up with.
The reactions in which the products can recombine to form reactants are called reversible reactions. These reactions never go to completion. They are represented by a double arrow between reactants and products.
The arrow between the reactants and products in a chemical equation represents the direction of the chemical reaction. It indicates that the reactants are being transformed into the products.
The change in entropy between products and reactants in a reaction
The h reaction is the difference between Hf products and Hf reactants - apex
The reactants are compounds that react to form new compounds (the products). apex
It is a big difference between the properties of reactants and products; an element is not a compound.
The amount of heat given off by the reaction
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
the elements contained in the reactants are equal to those in the products. e.g. 4H +O2 -> 2H20
