Final answer:
Without the provided enthalpy change of the reaction involving KCl and O2 to form KClO3, we cannot calculate the exact amount of heat released for the reaction of 3.025 grams of KCl.
Step-by-step explanation:
The student's question relates to determining the amount of heat released when a certain mass of potassium chloride (KCl) reacts with oxygen to form potassium chlorate (KClO3). Unfortunately, the provided excerpts do not contain a direct thermochemical equation for this reaction. To calculate the heat released, we would need the enthalpy change (ΔH) for the reaction involving KCl and O2 forming KClO3, which is not provided in the excerpts.
However, as a hypothetical example, if we were given an enthalpy change value, we would start by converting the mass of KCl to moles using its molar mass. Then, using stoichiometry based on the balanced chemical equation, we would determine how much heat is released per mole of KCl reacted. The calculation would involve multiplying the moles of KCl by the given enthalpy change value (assuming it to be provided).
Since the specific details of the enthalpy change for the reaction are not given, we are unable to provide an accurate heat calculation for this question.
