Double Replacement Precipitation Reactions Determine whether an ionic double replacement reaction has occurred.If I place different amounts of ionic solutions in a well plate‚ then I will be able to determine which of the solutions has had an ionic double reaction placement because I will use the solubility rules to decide which product produced the solid precipitate.Place five drops of silver nitrate into well A1 through A4. Place five drops of Iron (III) Nitrate into rows B1 through B4. Place

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

each other. Atoms interact by transferring‚ sharing or rearranging their electrons in a way that allows them to achieve a full shell of electrons which makes the atom stable. In compounds‚ there are two main types of bonding; ionic bonding and covalent bonding. Ionic bonding is usually found in compounds of a metal and a non-metal. This type of bonding involves the complete transfer of at least one electron from one atom to another. It is normally the metal atom which donates the electron

1. What is an ionic bond? Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion‚ which then result in attraction. 2. What is a covalent bond? A covalent bond is a bond that occurs when atoms in a molecule share a pair of electrons. For example‚ “the

The way elements are organized on a periodic table has to do with the characteristics that they hold. There are groups‚ periods‚ compound formation and color coordination in a periodic table.
