WebOct 27, 2024 · The specific heat of water is approximately 4.18 J/g °C, so we use that for the specific heat of the solution. Substituting these values gives: qsolution = (4.184J / g°C)(1.0 × 102g)(28.9°C − 22.0°C) = 2.89 × 103J Finally, since we are trying to find the heat of the reaction, we have: qreaction = − qsolution = − 2.89 × 103J WebA: Click to see the answer. Q: When 435 J of heat is added to 3.4 g of olive oil at 21°C, the temperature increases to 85°C. What….
