WebMay 17, 2024 · Explanation: The idea here is that you can use the heat absorbed by the solution to find the heat given off by the dissolution of the salt. More specifically, you can assume that ΔH diss = − qsolution The minus sign is used here because heat lost carries a negative sign. To find the heat absorbed by the solution, you can use the equation WebSo delta H is equal to qp. Let's say we are performing a chemical reaction, an aqueous solution under constant atmospheric pressure. The reactants and products of that chemical reaction make up the system and everything else makes up the surroundings. d \u0026 t body shop dayton oh
