A cubic piece of platinum metal (specific heat capacity = 0.1256 J/°C･g) at 200.0°C is dropped into 1.00 L of deuterium oxide ('heavy water,' specific heat capacity = 4.211 J/°C･g) at 25.5°C. The final temperature of the platinum and deuterium oxide mixture is 35.1°C. The density of platinum is 21.45 g/cm³ and the density of deuterium oxide is 1.11 g/mL. What is the edge length of the cube of platinum, in centimeters?
A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.7090 g sample of adipic acid (C6H1004) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.201×10° g of water. During the combustion the temperature increases from 22.33 to 24.58 °C. The heat capacity of water is 4.184 J gloc!. The heat capacity of the calorimeter was determined in a previous experiment to be 799.0 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of adipic acid based on these data. CGH1004(s) + (13/2) O2(g) → 5 H,O(1) + 6 CO2(g) + Energy Molar Heat of Combustion = kJ/mol
A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 1.4710 g sample of maleic acid (C4H4O4) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1159 g of water. During the combustion the temperature increases from 22.46 to 25.59 °C. The heat capacity of the calorimeter, not including the surrounding water, was determined in a previous experiment to be 852.2 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of maleic acid based on these data. Assuming that no energy is lost to the surroundings, what is the molar heat of combustion of maleic acid, based on these data? (in kJ/mol). C4H4O4(s) + 3O2(g) → 2 H2O(l) + 4 CO2(g) + Energy
