the sentence have the exact same meaning. This still doesn’t mean that it is a language because it can directly translate into English which contradicts the Worf theory of language.) b) The following two equations are examples of complicated chemical equations. It would take a large amount of time and space to translate either of these two into English. 1) Chemistry also has its own rules (grammar) c) Both hydrogen and oxygen are “special” elements that, when written by themselves

www.asbiology101.wordpress.com An introduction to the chemistry behind biomolecules What is biochemistry? Well, it’s the study of biology at a molecular level. So the emphasis of this unit is the biological significance of chemical molecules. As part of the course, there are six biological molecules that you need to know about: CH2OH Carbohydrates O H H OH OH These molecules are one of many vital to life. They are used for energy (for both storing and supplying energy)

microscopic particles together. In the case of molecules whose atoms are connected by covalent bonds, such intermolecular forces may be of three types. All molecules are attracted together by weak London forces. These depend on instantaneous polarization and increase in strength with the size of the molecular electron cloud. When a molecule contains atoms whose electronegativities differ significantly and the resulting bond dipoles do not cancel each other’s effects, dipole forces occur. This results in higher

water (40℃), the unexposure area was removed. 8. The exposure gauze was dryed at low temperture. Results and Discussion Sample attachments: Untreated material Dyed (reactive dye)material Follow up questions 1. What is the chemical nature of the water repellent finishing agent used in the experiment? Water repellent agent is a coating added to fabrics to prevent the outer layer of fabric from becoming saturated with water and make the fabric make them water-resistant (or hydrophobic)

different kinds of atoms. A chemical reaction is a rearrangement of atoms; atoms can be neither created nor destroyed. BONDS BETWEEN ATOMS: Bond between atoms, the very heart of bonding is the attraction between positive and negative charges, specifically the positive charge of the nucleus and the negative charge of the electrons. The varying tendencies of atoms to gain or lose electrons allow them to attract one another in various ways and form different kinds of bonds. ATOMIC STRUCTURE: Protons

A typical halogen bond is denoted by the three dots in R–X…Y. R–X is the halogen bond donor, X is any halogen atom with an electrophilic (electron-poor) region, and R is a group covalently bound to X. In some cases, X may be covalently bound to more than one group. It may also form more than one halogen bond. Y is the halogen bond acceptor and is typically a molecular entity possessing at least one nucleophilic (electronrich)
