When potassium chlorate is heated, potassium chloride and oxygen are formed. What type of chemical reaction is it?
a. Combination reaction

d. Acid-base reaction<\/p>\n\n\n\n

    <\/ol>\n\n\n\n

    The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

    The correct answer is c. Decomposition reaction<\/strong>.<\/p>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n

    A decomposition reaction<\/strong> is a type of chemical reaction where a single compound breaks down into two or more simpler substances, usually under the influence of heat, light, or electricity. The general form of a decomposition reaction is:<\/p>\n\n\n\n

    [
    \\text{AB} \\rightarrow \\text{A} + \\text{B}
    ]<\/p>\n\n\n\n

    In the case of potassium chlorate (KClO\u2083)<\/strong>, when it is heated, it breaks down into potassium chloride (KCl)<\/strong> and oxygen gas (O\u2082)<\/strong>. The chemical equation for this reaction is:<\/p>\n\n\n\n

    [
    2 \\text{KClO\u2083} \\xrightarrow{\\text{heat}} 2 \\text{KCl} + 3 \\text{O\u2082}
    ]<\/p>\n\n\n\n

    This is a typical example of a decomposition reaction because potassium chlorate decomposes into two simpler products: potassium chloride and oxygen gas.<\/p>\n\n\n\n

    Why Other Options Are Incorrect:<\/h3>\n\n\n\n
      \n
    • a. Combination reaction:<\/strong> In a combination reaction, two or more reactants combine to form a single product. For example, if hydrogen and oxygen combine to form water (H\u2082 + O\u2082 \u2192 H\u2082O), it is a combination reaction. This is not the case here, as potassium chlorate is breaking down into two substances, not combining.<\/li>\n\n\n\n
    • b. Displacement reaction:<\/strong> A displacement reaction occurs when one element displaces another in a compound. For example, in the reaction of zinc with hydrochloric acid (Zn + 2HCl \u2192 ZnCl\u2082 + H\u2082), zinc displaces hydrogen. In the potassium chlorate reaction, no element is displacing another; rather, potassium chlorate is breaking down.<\/li>\n\n\n\n
    • d. Acid-base reaction:<\/strong> An acid-base reaction typically involves the reaction of an acid and a base to form water and a salt. For example, hydrochloric acid reacting with sodium hydroxide (HCl + NaOH \u2192 NaCl + H\u2082O) is an acid-base reaction. Potassium chlorate breaking down does not involve an acid or a base, ruling this out.<\/li>\n<\/ul>\n\n\n\n

      Thus, the reaction involving the breakdown of potassium chlorate into potassium chloride and oxygen is a classic decomposition reaction<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
