Since the temperature increased , the reaction is exothermic. (to 3 significant figures). Problem Type 3: Neutralization Reactions Example Problem: is mixed with . The temperature rises from 21.0∘C21.0 raised to the composed with power C 34.5∘C34.5 raised to the composed with power C . Calculate the enthalpy of neutralization. Step 1: Calculate the total mass of the liquid. Step 2: Calculate . Step 3: Calculate moles of water formed. Since it is a 1:1 reaction, are produced. Step 4: Calculate . Final Answer: 4. Common Pitfalls to Avoid on Chemsheets Assignments

Remember: In calorimetry, heat lost by reaction = heat gained by water + calorimeter (sometimes the calorimeter's heat capacity is ignored if small). Since the temperature increased , the reaction is exothermic

The workhorse of calorimetry is the equation that connects heat ($q$), mass ($m$), specific heat capacity ($c$), and temperature change ($\Delta T$): The temperature rises from 21

Calculate the heat required (in kJ) to raise the temperature of 250.0 g of water from 22.0°C to 98.0°C. The specific heat of water is 4.18 J/g°C.
