Magnesium sulfate is often used in first-aid hot packs, giving off heat when dissolved in water. A coffee-cup calorimeter at 25 degrees celsius contains 15.00 mL of water at 25 degrees celsius. A 2.00-g sample of magnesium sulfate is dissolved in the water and 1.51 kJ of heat are evolved. What is the final temperature (celsius) of the solution when density of water is 1.00 g/mL and the specific heat of water is 4.18 J/g-degree celsius?

Hazard Analysis and Design in Chemical Engineering

Hazard is the intrinsic property of a material or process which harms the people, buildings, or environment. Health, safety, hazard, risk assessment, loss prevention, and environmental consideration play an important role while designing a chemical processing plant. Hazard is often confused with risk. Risk measures the magnitude of loss and injury of likelihood incidents or the consequence and frequency of incidents.
