DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. In general, we look at what occurs and try to learn how it happens. Common patterns describe the changes. Addition reactions – two molecules . combine. Elimination reactions – one molecule splits into two. Thermodynamic Control of Reactions. Enthalpy. Bond Energies. Forming stronger. bonds favors. reactions.. Molecules with. strong bonds are. more stable.. Entropy. Randomness. Reactions that. Synthesis reactions. Decomposition reactions. Single replacement reactions. Double replacement reactions. (Precipitate reaction). Chemical Reactions can be written as:. Word equation. Chemical equation. Add the new notes to your . table of contents. , and then turn to the next clean page and set up your title and date. Tape the two slides into your INB flat down, directly under your title - they do not need to flip up. Agenda. :. Warm up. Intro to the world of chemistry – . Episode 13 – the driving forces of reactions . Notes – Energy changes and Reaction rates . Complete WS: Heat and endothermic / exothermic reactions . Chemical Reactions. A . chemical reaction . is a process that changes, or transforms, one set of chemicals into another by changing the chemical bonds that join atoms in compounds. . @Mass and energy are conserved during chemical transformations.@. THINK ABOUT IT . Living things are made up of chemical compounds, but chemistry isn’t just what life is made . of—chemistry is also what life does. . . Everything that happens in an organism. —its growth, its interaction with the environment, its reproduction, and even its movement. Changes or transforms chemicals into . other. chemicals. Ex: Iron + Oxygen . . Iron Oxide (rust). Physical Science Review. What is the product?. What are the reactants?. Chemical formula. . shows the kind and proportion of atoms of each element that occurs in a particular compound. 1. Metal . carbonates such as calcium carbonate break down when heated strongly. This is called . thermal decomposition. . Here are the equations for the thermal decomposition of calcium carbonate. :. 18. O AT 35 MEV/NUCLEON ON . 9. BE AND . 181. TA TARGETS. Erdemchimeg.

These are the OPPOSITE of neutralization reactions (i.e. acid-base reactions). Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base.. All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. .
