PPT-12.5 Reactions of Gasses and Gas Stoichiometry

Gas Stoichiometry Recall The law of combining volumes W hen gases react the volumes of the reactants and products react in whole number ratios if the temperatures and pressures are constant . Made famous by S. Ohno, who suggested WGD can be a route to. . evolutionary innovation (focusing on . neofunctionalization. ). Ohno proposed in the 1970s that vertebrate lineage underwent two WGDs . Kinetic molecular theory. Pressure. Introduction. Earth’s atmosphere is a gaseous solution composed of mostly nitrogen and oxygen. The atmosphere is important for life on earth. Provides . a medium for many chemical reactions with waste products. By Myre and William. Gasses. Gasses are particles that float from earth to the . atmosphere and its particles go around to fill every place in a container and when the . they are open they will go to every space around.. Courtney. Good Thing/ Bad Thing. Traps heat so that it doesn’t get lost in space. Keeps oxygen in our atmosphere. Greenhouse gasses absorb infrared radiation (protects us from getting burnt up by the radiation from the sun). An Ideal Gas. All gas laws are based on the assumption that gasses behave “ideally”. An . i. deal gas:. Moves in all directions and in straight lines. There is no loss in kinetic energy in collisions. Fluids. Gasses. Liquids. Ideal Gas. Gasses with particles that undergo . elastic. collisions. Only exist under certain conditions. Low heat. Low pressure. Pressure. Pressure. Barometer. Boyles Law. Boyle’s law shows the kinetic theory mathematically. . Halvor M. Halvorson. 1. , Chris L. Fuller. 2. , Sally A. Entrekin. 3. , J. Thad Scott. 4. , and Michelle A. Evans-White. 1. 1.

Stoichiometry is the study of the relationships or ratios between two or more substances undergoing a physical or chemical change. We will be taking steps to solve the different equations. It’s a process that allows us to mathematically convert and calculate the relationships between the amount of reactants and products in a chemical reaction.. Graphical representation . Example: . for every O2 molecule,. Things you should know so far…. Energy transfer – endothermic vs. exothermic. Energy diagrams . Internal energy (including work). Heat equation. Calorimetry. and conservation of energy. Molar enthalpy. 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.. 4.2: Classifying chemical reactions. Define three common chemical reaction types: . (1) precipitation; (2) neutralization; (3) redox. Classify reactions given a balanced chemical equation. Identify common acids & bases. Writing and balancing Chemical Equation. Classifying Chemical Reactions:. Precipitation Reactions. Acid-base Reactions. Decomposition Reactions (nonredox). Oxidation-Reduction Reactions. Reaction Stoichiometry. Objective. To know about . electrophilic. substitution reactions. Success criteria. Understand . the mechanism of the . electrophilic. substitution reactions of . benzene. Understand this for . halogenation.
