GIVING BRAINLIEST You are conducting a calorimetry experiment using a calorimeter with 500mL of water in its outer chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the water is 25°C. After the reaction, the temperature of the water is 57.4°C. Disregarding any heat loss to the walls of the container, calculate the ΔHr0. The specific heat of water is 4.18 J/(g•K).
