PPT-Reactions of Alkalis

3 understand that alkalis neutralise acids to make salts 4 recall that soluble hydroxides and carbonates are alkalis Higher 5 predict the products of the reactions of soluble hydroxides and carbonates with . Most common reactions for aromatics involve replacement of ring . hydrogens. by other atoms or groups . (substitution reactions). Mechanism of Electrophilic Aromatic Substitution Reactions. Electrophile. 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. Chemical Equations. This equation means:. 4 Al(. s. ) + 3 O. 2. (. g. ) 2 Al. 2. O. 3. (. s. ). 4 Al atoms + 3 O. 2. molecules yield 2 molecules of Al. 2. O. 3. 4 Al . moles. 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 . Starter:. What ions are found in acids?. What ions are found in alkalis?. What is the chemical formula for water? . give an example of a neutralisation reaction. use a pH meter to measure pH. observe the changes in pH during a neutralisation . Free Radicals. Chain Free Radical Reactions. Nonchain. . Free Radical . Reactions. Miscellaneous . Free Radical Reactions. . Chapter Five. Free Radicals. Properties of free radicals. 1. One or more unpaired electrons.. Alkenes. The commercial . process. of . hydrogenation is . used. to . convert the double . bonds. in . vegetable oils to . saturated. fats . such as those in margarine. . Learning . Goal . . Draw the condensed or line-angle structural formulas and give the names for the organic products of addition reactions of alkenes. Draw a condensed structural formula for a section of a polymer.. A need for a chemical is identified.. A “pilot plant” is set up to find out the requirements for production.. Costs are considered and balanced with potential profit. . A proper chemical plant is built costing millions of pounds but creating a lot of jobs. . Patel Sikora. What are Alkali Metals?. The alkali metals are located in Group 1 of the periodic table. They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed.. 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. 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.. Objective. To know about . electrophilic. substitution reactions. Success criteria. Understand . the mechanism of the . electrophilic. substitution reactions of . benzene. Understand this for . halogenation.
