This document provides a step-by-step example of balancing a chemical equation. It starts with an unbalanced equation for the combustion of ethane, C2H6, with oxygen. It then balances the atoms on both sides of the equation, showing that the balanced equation is C2H6 (g) + O2 (g) 2CO2 (g) + 3H2O (g). Finally, it scales up the balanced equation by multiplying coefficients to get the fully balanced equation: 2C2H6 (g) + 7O2 (g) 4CO2 (g) + 6H2O (g).Chem Unit6

Stoichiometry is the quantitative relationship between reactants and products in chemical reactions. Hess's law states that the enthalpy change of a reaction is independent of the pathway and depends only on the initial and final states. Using Hess's law, one can determine the enthalpy change of a reaction by adding the enthalpy changes of multiple steps that combine to give the overall reaction. The standard enthalpy of formation of a compound is the enthalpy change when one mole of the substance is formed from its elements in their standard states.Fenantridina

Acid deposition occurs when sulfur dioxide and nitrogen oxides emitted from the burning of fossil fuels react with water, oxygen, and other chemicals in the atmosphere to form acids. These acids can fall to Earth as rain, snow, fog or dry particles. Natural processes also produce acid deposition, but human activities such as burning coal and oil have increased acid deposition levels. Acid rain has a pH lower than 5.6 and can damage sensitive forests and lakes. The main pollutants that cause acid rain are sulfur dioxide and nitrogen oxides.Synthetic reagent pdf ppt
