PPT-Thermonuclear Reactions

in the Sun No Need for Confinement The enormous selfgravity of the sun holds it together There is no way the fuel can escape or the sun can blow itself apart So the nuclear reactions just keep . Most common reactions for aromatics involve replacement of ring . hydrogens. by other atoms or groups . (substitution reactions). Mechanism of Electrophilic Aromatic Substitution Reactions. Electrophile. Type 1: A metal combines with a nonmetal to form a binary salt.. Example: A piece of lithium metal is dropped into a container of nitrogen gas.. 6Li (s) + N. 2. (g) . → 2Li. 3. N (. aq. ). Synthesis Reactions. 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:. Chemical change. . Reactions with acid. . Reactions with oxygen . 7F. 7F Simple chemical reactions. Chemical change. . 7F Simple chemical reactions. 7F Chemical change – Changing materials. How many different materials can you see in this bedroom?. 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 . of Alkenes: Addition Reactions. Disparlure: sex attractant of the female gypsy moth.. (A type of . pheromone.. ). 2. I. Hydrogenation of Alkenes. Addition. Reactions. oleic acid. (unsaturated). stearic acid. 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. in the Sun. . No Need for Confinement!. The enormous self-gravity of the sun holds it together. There is no way the fuel can escape (or the sun can blow itself apart).. So the nuclear reactions just keep . Nunc Agenda: Write the formula for photosynthesis. Quaestio: How do plants capture the sun’s energy?. Nunc Agenda: What do you think photolysis means?. The Plant Cell. Chloroplast Structure. Chloro. 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.. 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. . 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. O.
