and Net Ionic Equation Going back to our first concept or topic‚ we’ve learn how to identify the Oxidizing and Reducing agent and the Oxidation as well as the Reduction. In this part of the Redox reaction or in this step‚ it is very important that you already know the Oxidizing and Reducing agent for us to find the half reaction. In this step or part‚ we will also learn how to balance using the addition of electrons in both sides if necessary. After this step we can now write the net ionic equation

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse

systematic naming system. This naming system‚ aside from organization also provides the reader with information about the given element. There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary ionic compounds‚ for example NaCl‚ which is named Sodium Chloride. Na having a positive oxidation number goes first followed by Cl which having a negative oxidation number goes

Ionic – A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion. Covalent - A chemical bond that involves sharing a pair of electrons between atoms in a molecule. 2. Explain the structure of metals‚ ionic compounds‚ covalent molecules and covalent

Experimental Prep and Optimum wavelength Selection An ionic Iron solution with a known concentration of 4.047x10-3 M was obtained. A 250-mL sample of a 10-fold dilution of this ionic iron solution and 5 drops of concentrated HNO3 was made. This solution served as the source of ionic Iron for the remainder of the lab and was labeled “stock ionic Iron solution.” Next‚ a 50-mL aqueous ionic Iron and FerroZine® complex solution was prepared by adding 5.00mL stock ionic Iron‚ 3-mL of acetic acid buffer‚ 2-mL of 5%
