A solution of Lead Nitrate reacts with a solution of Aluminium Chloride. // Solution means in water = (aq) //
 * __Writing Equations with compounds__ Name: ___ **


 * Step 1. Determine the symbol and charge of each ion (the numerals in represent the ion’s charge) but write the cation (+ ions) before the non-metal anion(s) (- ions) except for substances with acetate.**


 * || = CATIONS = ||  ||   || ** ANIONS ** ||   ||
 * ** 1+ ** || ** 2+ ** || ** 3+ ** || ** 1- ** || ** 2- ** || ** 3- ** ||
 * Ammonium NH4+ || Barium Ba2+ || Aluminium Al3+ || Bicarbonate HCO3- || Carbonate CO32- || Nitride N3- ||
 * Cuprous (I) Cu+ || Beryllium Be2+ || Chromium Cr3+ || Bromide Br- || Chromate CrO42- || Phosphate PO43- ||
 * Hydrogen H+ || Calcium Ca2+ || Ferric (III) Fe3+ || Chloride Cl- || Dichromate Cr2O72- || Phosphide P3- ||
 * Lithium Li+ || Copper (II) Cu2+ ||  || Chlorate ClO3- || Zincate Zn(OH)42- ||   ||
 * Potassium K+ || Iron (II) Fe2+ ||  || Permanganate MnO4- || Silicate SiO32- ||   ||
 * Silver Ag+ || Lead (II) Pb2+ ||  || Acetate CH3COO- || Oxide O2- ||   ||
 * Sodium Na+ || Magnesium Mg2+ ||  || Fluoride F- || Peroxide O22- ||   ||
 * || Strontium Sr2+ ||  || Hydride H- || Sulfate SO42- ||   ||
 * || Tin Sn2+ ||  || Hydroxide OH- || Sulfide S2- ||   ||
 * || Zinc Zn2+ ||  || Iodide I- || Sulfite SO32- ||   ||
 * || Mercury Hg2+ ||  || Nitrate NO3- || Thiosulfate S2O32- ||   ||
 * ||  ||   || Nitrite NO2- ||   ||   ||

eg. Al3+Cl-, Charge number of Al is a 3 and the charge number of Cl is a 1 so Al1Cl3 but write it as AlCl3 eg. Pb2+NO3-. Charge number on Pb is a 2, and NO3 is only a 1 so Pb1(NO3)2 but write it as Pb(NO3)2.
 * Step 2. To write a chemical formula, write __ONE__ of each ion & balance the ion charges so the total is 0 by writing the required coefficient to the __bottom right of the ion__ ** . **For multiples of an atom group, use .**

Balancing equations
Use this simulation to learn how to do this When you click on this image a java file is downloaded - it may take a while (maybe even 120 seconds) depending on the speed of your internet link. Its well worth the wait. media type="custom" key="10181559" Now work on balancing equations worksheets and try balancing the equations there using these ideas Write some bullet points on what you learnt from this simulation. Then complete the test example on the assignment's submission page.

Here is a worksheet to practice writing and balancing equations







Types of elements Metals - hear a song about their properties or try this one about their position in the periodic table Transition metals Nonmetals metaloids
