A 5.80 g sample of SiH4 and an excess of oxygen were placed in a reaction container surrounded by 3.40 kg of water. The initial temperature of the water was 14.10°C. At the end of the reaction, the temperature of the water was 48.90°C. Assume the heat was completely absorbed by the water and no heat was absorbed by the reaction container or the calorimeter or lost to the surroundings. Calculate the heat released in the reaction. The specific heat of water is 4.184 J/g·°C.
