PPT-7.2 Types of Reactions

In a combustion reaction a candle burns using the oxygen in the air Learning Goal Identify a reaction as a combination decomposition single replacement double replacement or combustion. Most common reactions for aromatics involve replacement of ring . hydrogens. by other atoms or groups . (substitution reactions). Mechanism of Electrophilic Aromatic Substitution Reactions. Electrophile. In addition to substitution, alkyl halides can also undergo elimination reactions, which lead to the formation of alkenes.. As with substitution reactions, elimination reactions come in two mechanistic types:. 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. 1 – Nature of Chemical Reactions. 2 – Chemical Equations. 3 - Reaction Types. 4 – Reaction Rates and Equilibrium. State Standards. CLE.3203.1.9 – Apply the Laws of Conservation of Mass/Energy to balance chemical equations. 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. Part . 1: Decomposition and Synthesis Reactions. . Objectives. -To identify decomposition and synthesis chemical reactions. -To predict the products of these two types of reactions. 2. Symbols in . Envenomations. Chapter 16. Allergic Reactions. Allergic reaction. Exaggerated immune response to any substance. Histamines and . leukotrienes. Chemicals released by the immune system. Anaphylaxis. Extreme allergic reaction. Types of Reactions. Types of Reactions. There are . 9. . main types of reactions we will examine:. Combustion. Substitution. Addition. Halogenation. , . Hydrogenation, . Hydrohalogenation. , Hydration. Synthesis reactions. Decomposition reactions. Single replacement reactions. Double replacement reactions. (Precipitate reaction). Chemical Reactions can be written as:. Word equation. Chemical equation. Can you spot three (3) differences?. Can you spot the differences in the reactions?. (1) 2Mg. (s. ) . O. 2(g) . → . 2MgO. (s. ) . (2). CaCO. 3(s) . →. . CaO. (s) . CO. 2(g). (3) . NaOH. (. CONTENTS. CHEMICAL REACTION. CHARACTERISTICS OF CHEMICAL REACTION. TYPES OF CHEMICAL EQUATION. BALANCING OF CHEMICAL EQUATION. HOW TO MAKE EQUATION MORE INFORMATIVE. The . risk for development of a drug eruption is related to the following factors: age, gender, dose, and the nature of the medication itself. . Females . are . 1.3-1.5 . times more likely to develop drug eruptions, except in children under the age of 3 where boys are more likely to be affected. . Our estimates of pressures and temperatures experienced by rocks during metamorphism are based on metamorphic reactions.. Mineral Reactions. There are two basic types of mineral reactions:. Continuous. Write your answer in your. . science journal.. Quiz. 1. How . many molecules of oxygen gas in the reactant (O. 2. ) are needed to balance this equation?. CH. 4. + O. 2. → 2CO. 2. + 4H. 2.
