Global Warming. Kate O’Brien. Solar radiation. Infrared radiation. atmosphere. Solar radiation. Some radiation is reflected by the Atomsphere & Earth’s surface. atmosphere. Most radiation in absorbed by earth’s surface & warms it. Infrared radiation.

Types of Chemical Reactions. A chemical equation describes a chemical change. The Law of Conservation of Mass says that the number and kind of atoms going INTO a chem. rxn must be the same as the number and kind of atoms coming OUT.

Chapter 5: thermochemistry. By Keyana Porter Period 2 AP Chemistry. What is thermochemistry?. Thermodynamics: the study of energy and its transformations Thermochemistry is one aspect of thermodynamics The relationship between chemical reactions and energy changes

Chemical Reactions. Introduction. Chemical Equations. chemical change = chemical reaction A chemical equation is a shorthand way of showing what happens when a chemical reaction occurs. Na + Cl  NaCl Symbols and formulas in the equation represent reactants and products.

Types of Chemical Reactions. A chemical equation describes a chemical change. The Law of Conservation of Mass says that the number and kind of atoms going INTO a chemical reaction must be the same as the number and kind of atoms coming OUT.

Entropy. Spontaneity. ____________ process – a process that occurs without intervention can be fast or slow. Entropy. ____________ (s) – the measure of molecular randomness or disorder Think of entropy as the amount of chaos. Entropy. Predict which has the highest entropy

第四节 燃 烧 热 和 中 和 热. 2H 2 （气） + O 2 （气） = 2H 2 O （液） = -571.6 kJ/mol. H 2 （气） + ½O 2 （气） = H 2 O （液） = - 285.8 kJ /mol. H. H. H. H. H 2 （气） + ½ O 2 （气） = H 2 O （气） =- 241.8 kJ /mol. 2C( 固 ) + O 2 ( 气 ) = 2CO( 气 ) =-110.5 kJ /mol. 一、燃烧热.
