Imagine that you dissolve sucrose, C12H22O11(s), in water. a. Write a balanced equation for this reversible process. b. In which direction does the process proceed if you place a tiny amount of sugar in a large pot fi lled with water? c. In which direction does the process proceed if you allow the water to evaporate from a sugar solution?
Chapter 5 Textbook Notes 5.1 Hydrogen, oxygen, and water When two or more elements combine to form a compound, an entirely new substance results 5.2 Types of chemical bonds A chemical bond is the force that holds atoms together in a compound Chemical bonds form because they lower the potential energy of the charged particles that compose atoms Ionic bond – the bond that forms between a metal and a nonmetal; electrons are transferred from the metal to the nonmetal o The metal atom becomes a cation and the nonmetal becomes an anion o An ionic compound is formed with a lattice structure of alternating cations and anions Covalent bond – the bond that forms between two or more nonmetals o
