A reaction releases 250 kJ of heat energy when 2 moles of reactant are converted to product. Calculate the enthalpy change (ΔH) for the reaction.
A calorimeter contains 100g of water at 20°C. A 50g block of metal at 80°C is added to the calorimeter. The final temperature of the water is 25°C. Calculate the specific heat capacity of the metal. calorimetry 1 chemsheets answers
\[c = rac{-2090}{50 imes 55} = 0.76 J/g°C\]
Calorimetry is the measurement of heat changes in a system. It involves the use of a calorimeter, a device that measures the heat transferred between a system and its surroundings. Calorimetry is used to determine the enthalpy change (ΔH) of a reaction, which is a measure of the total energy change in a system.
$ \(ΔH = Q / n = -250,000 / 2 = -125,000 J/mol = -125 kJ/mol\) $ \[Q_{water} = m_{water}c_{water}ΔT_{water} = 100 imes 4
$ \(Q = mcΔT = 50 imes 0.38 imes (50 - 20) = 50 imes 0.38 imes 30 = 570J\) $
A 25g sample of water is heated from 10°C to 30°C. The specific heat capacity of water is 4.18 J/g°C. Calculate the heat energy transferred.
