4 pts Question 6 A 600 g piece of metal was heated to 100 °C and then put it into 100 mL of water initially at 23.7 °C). The metal and water were allowed to come to an equilibrium temperature, determined to be 278°C. Assuming no heat lost to the environment calculate the specific heat of the metal (the specific heat of water is 1.00 cal/g °C). X DE E
Calorimetry. Specific Heat of a Metal and Heat of Reaction 4. When 25.0 mL of 1.00 M sodium hydroxide, NaOH(aq) is added to 25.0 mL of 1.00 M sulfuric acid, H,SO, (aq), at 22.3°C, the temperature rises to 31.2°C. Assume the solution is sufficiently dilute, so its specific heat is 4.184 J/gºC and its density is 1.00 g/ml. a.
