For this lab, lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) will be reacted together to demonstrate double replacement reaction between 2 ionic compounds. This was shown when chromate replaced the nitrate and formed lead (II) chromate, and when the nitrate replaced the chromate and formed potassium nitrate, which is shown in the following equation:…
Begin building the chemical equation by dragging a sodium ion to the first product box and a nitrate ion to the second product box. Place your cursor over each ion to display its charge. Since these ions have equal but opposite charges (+1 and -1), you do not need to drag any additional ions to this area. NaNO3 is a valid chemical formula.…

Introduction – A double replacement reaction is a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound. If you have the reactants of two reaction solution that you can determine the products. All you need to do is pair the positive parts of the compounds with the other compounds negative part. Once you find the products you can determine their phase of matter by using Table H. You can also use Table F to determine the solubility guidelines for aqueous solutions. If the product falls under soluble or exceptions to insoluble it is in the aqueous stare. If the product falls under insoluble or exception to soluble it is a precipitate. Once you have completed those steps you can determine if a equation went to completion or not. In order for a reaction to go to completion it must have one of the following three things. First, a gas is produced. This gas is usually H2, O2, or CO2. Secondly, a covalent compound (such as water) is formed. Finally, a precipitate (solid) is formed. When none of those things happen it is considered to be "no reaction." When one of those things does happen the reaction is considered to be "completed." It is considered to be completed because all of the reagents in the sample have completely reacted out.…

Doing what’s right and honest almost always brings a temporary setback and the rewards for doing so often take time to emerge. This is the story of Edgar P Benchley’s life. Edgar, the owner of Tortoise Enterprises is a man cursed with responsibility, that of which is not often valued by the world. Edgar may or may not have turned out as a respectable man if it hadn’t been for his Pooka Ari. Pooka are mythical creatures not everyone can see. Edgars Pooka, a very large rabbit, was on a mission to make sure he was honest, no matter what.…
