The document discusses different types of carbonyl compounds including aldehydes, ketones, carboxylic acids, and esters. It covers their structures, naming conventions, properties, examples and how they are related through oxidation-reduction reactions. Aldehydes contain a carbonyl group bonded to at least one hydrogen, while ketones have the carbonyl group bonded to two carbon groups. Carboxylic acids contain both a carbonyl and hydroxyl group. Esters are derivatives of carboxylic acids where the hydroxyl is replaced by an alkoxy group from an alcohol.
26sec2
Alcohols contain an -OH functional group called a hydroxyl group. They are classified based on the number of carbon groups attached to the carbon bearing the hydroxyl. Alcohols exhibit hydrogen bonding and solubility in water. Common alcohols include isopropyl alcohol, ethylene glycol, glycerol, and ethanol. Ethers have the general formula R-O-R and are named by alphabetizing the two carbon groups. Examples include diethyl ether, which was historically used as an anesthetic.
26sec4
Polymers are large molecules formed from smaller molecules called monomers. There are two main types of polymers: addition polymers and condensation polymers. Addition polymers are formed when unsaturated monomers react through addition reactions, examples include polyethylene, polypropylene, polystyrene, and polyvinyl chloride. Condensation polymers are formed through condensation reactions with the loss of water or another small molecule, examples include polyethylene terephthalate, nylon, and Kevlar. Plastics are identified by code numbers that indicate the type of polymer resin used, such as PETE for polyethylene terephthalate in water bottles.
Ch 17 alternative energy sources
Solar energy is the sun's energy that is harnessed and can be used as an alternative to fossil fuels. The sun's energy comes from nuclear fusion reactions, with a small amount of mass converted to a large amount of energy. Only a tiny fraction of the sun's energy reaches Earth, mostly as infrared and visible light. This solar energy can be converted into thermal or electrical energy through the use of solar panels and collectors. While solar energy is clean and free, its intermittent nature and high costs have limited its widespread adoption. New technologies aim to improve solar energy storage to increase its viability as a renewable alternative energy source.

Nuclear reactors are designed to generate electricity through nuclear fission. The core holds nuclear fuel rods and control rods, and uses coolant to generate steam that turns turbines to produce electricity. When uranium-239 is split in the active reactor zone, it produces plutonium-239 through a fission reaction harness by Einstein's equation relating mass and energy. Cooling towers then cool the steam for recycling in the process.
Ch 16
Nuclear energy involves subatomic particles like protons, neutrons and electrons that make up atoms. Atoms of the same element have the same number of protons but can have different numbers of neutrons, forming isotopes. Unstable isotopes become stable through radioactive emissions like alpha, beta, and gamma radiation of varying penetrating power that can be stopped by materials like skin, foil or concrete.
Ch 16 notes env.bio
This document contains questions about atomic structure, radioactivity, nuclear fission reactions, nuclear reactors, and nuclear waste. It asks about the subatomic particles that make up atoms, isotopes, radioactive decay, and the three types of radiation. It also asks about the process of nuclear fission, including what it is, what it produces, and how it can be depicted in a diagram. Finally, it addresses nuclear waste storage and disposal issues, as well as some historical nuclear accidents and their causes and impacts.
28.3
Fission and fusion are two types of nuclear reactions. Fission involves splitting heavy nuclei like U-235, releasing energy. It can be uncontrolled, as in atomic bombs, or controlled in nuclear power plants using moderators and control rods. Fusion combines light nuclei like hydrogen into heavier elements like helium and releases even more energy, but requires extremely high temperatures found in stars like the sun or experimental facilities on Earth.
28.2
Stable nuclei exist in the "band of stability" based on their neutron to proton ratio. Those with too many neutrons undergo beta decay to become more stable, while those with too many protons either capture electrons or emit positrons to become more stable. All nuclei above atomic number 83 are radioactive and undergo alpha decay. The half-life of a radioactive isotope is the time for half of it to decay, and varies greatly between isotopes. Nuclear transformations can occur naturally through radioactivity or artificially by bombarding nuclei with particles, allowing one element to be transformed into another.
28.1
This document summarizes key aspects of nuclear radiation and radioactive decay:
1) Radioactive decay occurs as unstable radioactive isotopes spontaneously emit radiation and decay into stable isotopes, releasing large amounts of energy in the process.
2) There are three main types of radiation emitted - alpha, beta, and gamma rays - which differ in their penetrating abilities and what they are composed of.
3) Radioactive decay challenges Dalton's atomic theory, which stated atoms are indivisible, as it involves atomic nuclei breaking down and emitting particles.
28.4
Ionizing radiation such as X-rays and radiation from radioisotopes can knock electrons off atoms and produce ions, but cannot be detected by human senses. Devices like Geiger counters, scintillation counters, and film badges can be used to detect and measure different types of ionizing radiation. Radiation has many uses including detecting trace elements, diagnosing and treating diseases like cancer, and tracing chemical reactions and the movement of substances in the body using radioactive tracers.
25sec4
This document discusses different types of hydrocarbon compounds. Cyclic hydrocarbons contain carbon chains attached to form rings, and are called "cyclo-" compounds. Aromatic hydrocarbons contain unsaturated carbon rings called arenes, with the simplest being benzene. Benzene has a six-carbon ring with alternating single and double bonds, and exhibits resonance due to the location of these bonds. Benzene derivatives are possible by substituting the ring with other groups like methyl, ethyl, or multiple groups including ortho, meta, and para positions.
25sec5
Natural gas and petroleum are fossil fuels formed from marine life buried in ocean sediments millions of years ago. Natural gas is primarily methane but also contains other alkanes like ethane and propane. It burns cleanly and is used widely for energy. Petroleum contains more complex hydrocarbons and must be refined to separate useful fractions like gasoline. Coal was formed from decaying plants over millions of years and ranges from peat to anthracite based on carbon content and other properties. It releases pollutants when burned but provides an important source of fuel.
25sec3
There are different types of isomerism including structural isomers, stereoisomers, geometric isomers, and optical isomers. Structural isomers have the same molecular formula but different structures. Stereoisomers have the same molecular structure but different arrangements of atoms in space. Geometric isomers differ in the geometry of substituted groups around a double bond, which can be in trans or cis configurations. Optical isomers contain asymmetric carbons and exist as left or right-handed stereoisomers.
25sec2
Alkenes and alkynes are types of unsaturated hydrocarbons. Alkenes contain carbon-carbon double bonds and have the general formula CnH2n. They are named with the suffix -ene and the double bond is given the lowest possible number. Alkynes contain carbon-carbon triple bonds and have the formula CnH2n-2. Acetylene is the simplest alkyne and is commonly used as fuel in torches.
Ch 25 sec1
This document discusses hydrocarbons and organic chemistry. It begins by explaining that organic chemistry originally referred to compounds from living organisms, but now refers to compounds containing carbon. The simplest hydrocarbons are alkanes, which contain only carbon and hydrogen in single bonds. Alkanes can be straight-chain or branched-chain. Straight-chain alkanes have carbons in a chain, while branched alkanes have other atoms like hydrogen attached to the carbon chain. The document provides examples of naming straight-chain and branched alkanes based on IUPAC nomenclature rules.

Hydrogen is the most abundant element in the universe but on Earth it is generally found in compounds. It has three isotopes - protium, deuterium, and tritium which is radioactive. Hydrogen is produced industrially through steam reforming of hydrocarbons and the water-gas shift reaction. It is used to make ammonia through the Haber process and for hydrogenation of oils. Noble gases are very unreactive and occur rarely in the atmosphere, though some like helium are used for balloons and breathing mixtures for divers.

These slides walk through the story of 1 Samuel. Samuel is the last judge of Israel. The people reject God and want a king. Saul is anointed as the first king, but he is not a good king. David, the shepherd boy is anointed and Saul is envious of him. David shows honor while Saul continues to self destruct.
