Kevin graphed the inequality x > 1. A number line going from negative 3 to positive 5. A closed circle is at 1. Everything to the right of the circle is shaded.

What mistake did Kevin make? Explain.

When hydrogen peroxide (h2o2) is added to potassium iodide (ki) solution, the hydrogen peroxide decomposes into water (h2o) and oxygen (o2). the chemical equation for the decomposition reaction is: 2h2o2—> 2h2o + o2. what is the role of the potassium iodide in this reaction? a. reactant. b. product. c. precipitate. d. catalyst.
