What is the absolute pressure at the bottom of a storage tank of oil 18-m deep that is open to the atmosphere? Take the density of oil to be 800 kg/m3.
A sample of naphthalene (C10H8) that has a mass of 0.7200 g is burned in a bomb calorimeter. The mass of the calorimeter is 1.580 kg, and its specific heat is 2.55 J/(g°C). As a result of the reaction, the temperature of the calorimeter increases from 22.00°C to 29.3&d...
The initial temperature of a bomb calorimeter is 28.50°C. When a chemist carries out a reaction in this calorimeter, its temperature decreases to 27.45°C. If the calorimeter has a mass of 1.400 kg and a specific heat of 3.52 J/(g°C), how much heat is absorbed by th...
In the reaction between formic acid (HCHO2) and sodium hydroxide, water and sodium formate (NaCHO2) are formed. To determine the heat of reaction, 75.0 mL of 1.07 M HCHO2 was placed in a coffee cup calorimeter at a temperature of 20.8 °C, and 45.0 mL of 1.78 M NaOH, also a...
