Chemistry

Question

Rosa was looking for patterns to help predict the products of chemical reactions. She recorded three similar decomposition reactions in the table.

1 Answer

  • Answer:

    1

    Explanation:

    A decomposition reaction is a chemical reaction in which one product is decomposed to form two or more products. In chemistry, decomposition is primarily achieved by heating the substance at high temperature.

    Chlorates normally are decomposed when they are reached at a significant high temperature and are normally used for oxidation purposes. In the given examples from the table:

    Sodium chlorate is decomposed to Sodium chloride and oxygen. Potassium chlorate follow the same principle and so will Lithium.

    So, the reaction becomes:

    2LiClO₃ ----> 2LiCl + 3O₂

    You can see that both Sodium chlorate (NaClO3) and Potassium chlorate (KClO3) gave exactly the same products. i.e. a chloride and oxygen.
