The formula to calculate Δ H rxn ° from Δ H f ° values is to be determined. Concept introduction: The standard enthalpy of reaction ( Δ H rxn ° ) is the enthalpy change associated with a reaction and the reactants and products associated with the reaction are at their standard state. On the other hand, the standard enthalpy of formation ( Δ H f ° ) is the enthalpy change of the formation of 1 mol of compound from its elements and the reactants and products, in this case, is also present in their standard state.

Answer 1

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.

Predict the major products of this organic reaction: HBr (1 equiv) cold ? Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
