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. Lecture 3 Topics. . Brown. , chapter 3. 1. Moles. . . 3.4. Molecular mass (aka . molecular . weight) . . 3.3. 2. Molar . converstions. Percent composition . 3.3. Empirical formulas . . THE OVERVIEW OF A COSMIC CLOUD. According to Merriam Webster:. Neb-u-la :. noun: \ ‘ne-bye-la. 1: any of numerous clouds of gas or dust in interstellar Space. What is a Nebula?. Nebulas are large clouds made of interstellar gas and dust . 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,. Lab Materials Set Up. The Greenhouse Effect. Good. . Bad. Global Warming. Good. . Bad. Water Vapor. Carbon Dioxide. Methane. Nitrous Oxide. The Greenhouse Gases. Carbon Dioxide (CO. 2. ). -Sources. Guiding Questions. How are dosages determined? . How are toxins measured and controlled?. . Which is better: eating beans and rice at separate meals . or together?. . Table of Contents. ‘Stoichiometry’. H6.1 Define partial pressure. Dalton’s Law of partial pressure states that the total pressure exerted by a mixture of gasses is the sum of the pressures exerted independently by each gas in a mixture. Limiting reactants. Percentage yield. Stoichiometry Problems. How many moles of KClO. 3. must decompose in order to produce 9 moles of oxygen gas? . = 6 mol KClO. 3. Problem: X mol. KClO. 3. . 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.
