What is the difference between standard enthalpy of formation, enthalpy of formation, and reaction enthalpy?
The standard enthalpy of formation is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states. Enthalpy of formation is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states, but it can be under non-standard conditions. Reaction enthalpy is the enthalpy change that occurs in a chemical reaction, which can be exothermic (heat is released) or endothermic (heat is absorbed).
-
What is enthalpy?
Enthalpy is a thermodynamic property of a system that represents the total energy of the system, including its internal energy and the energy required to maintain constant pressure. It is often denoted as H and is expressed in units of joules. Enthalpy is important in understanding and analyzing processes such as chemical reactions and phase changes, as it provides a measure of the heat content of a system. In practical terms, enthalpy change is often used to quantify the heat absorbed or released during a process at constant pressure.

What is the difference between bond enthalpy and formation enthalpy?
Bond enthalpy is the energy required to break a specific chemical bond in a molecule, while formation enthalpy is the energy change when one mole of a compound is formed from its elements in their standard states. Bond enthalpy is specific to a particular bond within a molecule, while formation enthalpy is a measure of the overall energy change in forming a compound. Bond enthalpy is typically measured in kilojoules per mole (kJ/mol), while formation enthalpy is also measured in kilojoules per mole (kJ/mol).

How to calculate the reaction enthalpy from the molar bond enthalpy?
To calculate the reaction enthalpy from the molar bond enthalpy, you need to consider the difference between the sum of the bond enthalpies of the reactants and the sum of the bond enthalpies of the products. First, calculate the total bond enthalpy of all the bonds broken in the reactants, and then calculate the total bond enthalpy of all the bonds formed in the products. The reaction enthalpy is then the difference between these two values, with the bond enthalpies of the products subtracted from the bond enthalpies of the reactants. This calculation allows you to determine whether a reaction is exothermic (releasing heat) or endothermic (absorbing heat).

Knowledge, Information, and Business Education in the British Atlantic World, 1620–1760
Accurate information is essential to successful business activity.The early modern period saw an increase in printed commercial information, including newspapers, printed exchange rates, and educational texts--part of the 'print revolution' that permeated all aspects of the early modern world.Rather than relying on externally-produced printed works, commercial agents retained agency in creating and sharing their own business and educational information, which was shared in other forms and prioritised and valued over printed material.This book explores the ways that merchants and other commercial agents learned about business in the early modern British Atlantic World.It considers how they acquired, dispersed, stored, and used information, as well as considering their contribution to creating and shaping that information.Prioritising a wide range of manuscript material held in disparate collections, including merchants' correspondence, letter-books, notebooks, family papers, exercise books, and ships' logs, Talbott explores the ways that knowledge, information, and business education was created, circulated, and used in the early modern British Atlantic World.It offers a new perspective on the exchange of business information in a period dominated by discussions of print, prioritising manuscript and oral forms of exchange.In doing so, it presents a more holistic account of the ways that networks of knowledge operated in early modern business, centralising the creation, circulation, and use of business information specifically by those individuals most involved in--and most affected by--its production.

What is the difference between standard formation enthalpy and enthalpy change?
Standard formation enthalpy is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states. It is a specific type of enthalpy change that is measured under standard conditions. Enthalpy change, on the other hand, is a more general term that refers to the overall change in enthalpy of a system during a chemical reaction or process, regardless of whether it involves formation of a compound or not. Enthalpy change can be positive (endothermic) or negative (exothermic), depending on whether energy is absorbed or released during the process.

What is Hess's law for standard formation enthalpy and combustion enthalpy?
Hess's law states that the total enthalpy change for a reaction is the same regardless of the number of steps taken to reach the final products. This principle can be applied to standard formation enthalpies and combustion enthalpies by using a series of known enthalpy changes to calculate the overall enthalpy change for a reaction. By manipulating and combining these known enthalpies, Hess's law allows us to determine the enthalpy change for reactions that may not be easily measured directly.

Is the lattice enthalpy always positive and the hydration enthalpy always negative?
The lattice enthalpy is not always positive and the hydration enthalpy is not always negative. The lattice enthalpy can be positive or negative depending on the strength of the ionic bond in a compound. For example, in some cases, the lattice enthalpy can be negative for compounds with very strong ionic bonds. Similarly, the hydration enthalpy can be positive or negative depending on the strength of the hydration of the ions in solution. For example, in some cases, the hydration enthalpy can be positive for ions that form strong interactions with water molecules.

What is Hess's law equation for standard formation enthalpy and combustion enthalpy?
Hess's law states that the overall enthalpy change for a reaction is the same regardless of the number of steps taken to reach the final products. For standard formation enthalpy, the equation is: ∆Hf°(products) = ∑∆Hf°(products) - ∑∆Hf°(reactants). For combustion enthalpy, the equation is: ∆Hcomb° = ∑∆Hf°(products) - ∑∆Hf°(reactants). These equations allow us to calculate the enthalpy change of a reaction using the enthalpies of formation of the reactants and products.
