  • Molecules of Murder : Criminal Molecules and Classic Cases
    Molecules of Murder : Criminal Molecules and Classic Cases

    Molecules of Murder is about infamous murderers and famous victims; about people like Harold Shipman, Alexander Litvinenko, Adelaide Bartlett, and Georgi Markov.Few books on poisons analyse these crimes from the viewpoint of the poison itself, doing so throws a new light on how the murders or attempted murders were carried out and ultimately how the perpetrators were uncovered and brought to justice.Part I includes molecules which occur naturally and were originally used by doctors before becoming notorious as murder weapons.Part II deals with unnatural molecules, mainly man-made, and they too have been dangerously misused in famous crimes.The book ends with the most famous poisoning case in recent years, that of Alexander Litvinenko and his death from polonium chloride.The first half of each chapter starts by looking at the target molecule itself, its discovery, its history, its chemistry, its use in medicine, its toxicology, and its effects on the human body.The second half then investigates a famous murder case and reveals the modus operandi of the poisoner and how some were caught, some are still at large, and some literally got away with murder.Molecules of Murder will explain how forensic chemists have developed cunning ways to detect minute traces of dangerous substances, and explain why some of these poisons, which appear so life-threatening, are now being researched as possible life-savers.Award winning science writer John Emsley has assembled another group of true crime and chemistry stories to rival those of his highly acclaimed Elements of Murder.

  • Molecules of Murder Set
    Molecules of Murder Set

    How can a plant as beautiful as the foxglove be so deadly and yet for more than a century be used to treat heart disease?The same is true of other naturally occurring molecules as will be revealed in these two books from award-winning author and chemist, John Emsley. Molecules of Murder and More Molecules of Murder deal with potential poisons from man-made and natural sources.Both books investigate the crimes committed with them, not from the point of view of the murderers, their victims, or the detectives, but from the poison used.In so doing the books throw new light on how these crimes were carried out and ultimately how the perpetrators were uncovered and brought to justice.The crimes include those committed by infamous murderers and also famous victims like Harold Shipman, Alexander Litvinenko and Georgi Markov. Each chapter starts by looking at the target molecule itself, its discovery, its chemistry, its often-surprising use in medicine, its effects on the human body, and its toxicology.The rest of the chapter is devoted to murders and attempted murders in which it has been used.But, be reassured that murder by poison is not the threat it once was, thanks to laws which restrict access to such materials and to the skills of analytical chemists in detecting their presence in incredibly tiny amounts.

  • 'Salts or molecules?'

    Salts are compounds formed from the reaction of an acid and a base, while molecules are made up of atoms bonded together. Salts are ionic compounds, meaning they are made up of ions, while molecules can be either ionic or covalent compounds. Salts have a specific crystalline structure and are often soluble in water, while molecules can have a wide range of physical properties and solubilities. Overall, salts and molecules are distinct types of chemical compounds with different structures and properties.

  • Which of the following molecules are dipole molecules and why?

    Molecules that have a dipole moment are considered dipole molecules. A dipole moment occurs when there is an uneven distribution of electron density within a molecule, resulting in a partial positive and partial negative charge. For example, molecules like water (H2O) and ammonia (NH3) are dipole molecules because of their polar covalent bonds, which create a separation of charge within the molecule. On the other hand, molecules like carbon dioxide (CO2) and methane (CH4) are nonpolar and do not have a dipole moment because the electronegativity of the atoms cancel each other out, resulting in a symmetrical distribution of charge.

  • What is the difference between compound molecules and element molecules?

    Compound molecules are made up of two or more different elements chemically bonded together, such as water (H2O) or carbon dioxide (CO2). Element molecules, on the other hand, are made up of two or more atoms of the same element bonded together, such as oxygen (O2) or nitrogen (N2). In compound molecules, the atoms are different, while in element molecules, the atoms are the same.

  • Why are water molecules permanent dipoles and carbon dioxide molecules not?

    Water molecules are permanent dipoles because they have a bent molecular shape with unequal sharing of electrons between the oxygen and hydrogen atoms. This results in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, creating a permanent dipole moment. On the other hand, carbon dioxide molecules are not permanent dipoles because they have a linear molecular shape with symmetrical distribution of the two oxygen atoms and the carbon atom. This results in equal sharing of electrons and no permanent dipole moment.

    In the Atoms and Molecules Meet leveled reader, fundamental science facts in chemistry are explained through simply written text and colorful, fun illustrations. Children will discover that everything we see, touch, and taste is made of atoms. Atoms are the fundamental building blocks of matter and can link together to make molecules. Electrons on the atoms form the links, or bonds, in molecules, and atoms and molecules can bond to make more molecules.Children will learn that chemical reactions occur when atoms and molecules link together and also when molecules break apart. These chemical reactions must follow rules that state which atoms and molecules are able to link. Several examples of reactions are given, showing some different atoms and molecules they can form. Examples are also given of ways in which some chemical reactions can been seen; for example, as indicated by bubbles, fire, small particles forming, or color change. Chemical reactions are occurring all the time, and examples of reactions that happen in everyday life are shown.A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations.

  • Why do heptan-1-ol molecules and water molecules not mix?

    Heptan-1-ol molecules and water molecules do not mix well because heptan-1-ol is a nonpolar molecule, while water is a polar molecule. Nonpolar molecules are not attracted to polar molecules, so they do not easily mix. Additionally, heptan-1-ol is hydrophobic, meaning it repels water, further preventing the two substances from mixing. This is due to the difference in the polarity and intermolecular forces between the two substances.

  • How are molecules recognized?

    Molecules are recognized through specific interactions between their chemical structures and complementary binding sites on other molecules. This recognition process involves the formation of non-covalent bonds such as hydrogen bonds, van der Waals forces, and electrostatic interactions. The shape, size, and charge distribution of molecules play a crucial role in determining their recognition by other molecules. Additionally, specific functional groups and chemical properties can also contribute to the recognition process.

  • See description, which molecules?

    The description does not specify which molecules are being referred to. It would be helpful to have more context or specific information in order to accurately identify the molecules in question. Without further details, it is difficult to provide a specific answer.

  • Search for dipole molecules.

    Dipole molecules are molecules that have a separation of positive and negative charges within the molecule. This separation creates a dipole moment, which results in the molecule having a positive end and a negative end. Examples of dipole molecules include water (H2O), hydrogen chloride (HCl), and ammonia (NH3). These molecules are important in various chemical reactions and interactions due to their polar nature.
