A single-replacement reaction, also known as a single-displacement reaction, is a chemical process in which one element replaces another element in a compound. This type of reaction typically involves an element and a compound reacting to produce a new element and a new compound. For example, when zinc reacts with hydrochloric acid, zinc displaces hydrogen to form zinc chloride and hydrogen gas. The general form of the reaction can be represented as A + BC → AC + B, where A is a more reactive element than B.

How do you Calculate delta U for a reaction?
To calculate the change in internal energy (ΔU) for a reaction, you can use the formula ΔU = Q + W, where Q is the heat exchanged and W is the work done. For a reaction at constant volume, ΔU can often be approximated by measuring the heat released or absorbed during the reaction. Additionally, if using standard conditions, you can calculate ΔU using the standard enthalpy of formation values of the reactants and products. Always ensure to account for the stoichiometry of the reaction when applying these principles.
