Word+Equations

=Can you write a word equation?= Word equations have the following pattern: name of reactant 1 + name of reactant 2 + ... name of product 1 + name of product 2 + ... The **reactants** are the substances with which you begin the reaction. The names of the reactants are listed before the arrow in the word equation. Transition words are used if there is more than 1 reactant. Ex. and, reacts with, combine, etc. The **products** are the substances made as a result of the reaction. The names of the products are listed after the arrow in the word equation. If there is more than 1 product "and" is used to separate them. Sometimes heat or energy is needed or formed in a reaction. Heat or energy is included in the word equation just like any other reactant or product. Include the state of each reactant and product from the shorthand: Magnesium metal combines with oxygen gas to make solid magnesium oxide and heat || A solution of sodium iodide is added to a solution of potassium nitrate to make a potassium iodide precipitate and a sodium nitrate solution. || Gaseous hydrogen and gaseous oxygen react to form water vapor. ||
 * Word equations** describe chemical reactions using words.
 * solid **(s) or precipitate**
 * liquid **(l)**
 * gas **(g)**
 * aqueous **(aq)** This means aqueous which means that the substance was dissolved in water or that it is in solution form. also solution
 * Examples:**
 * 1. || Mg(s) + O2(g)---> MgO(s)
 * 2. || NaI(aq) + KNO3(aq) > KI(s) + NaNO3(aq)
 * 3. || H2(g) + O2(g) ---> H2O(g)
