A Sample of Hexane: Calculating the Amount of Heat Released During Combustion
In this article, we will explore the concept of heat released during the combustion of a sample of hexane in a bomb calorimeter. The bomb calorimeter is a device used to measure the heat of combustion of a substance. In this case, we will calculate the amount of heat released during the combustion of a sample of hexane.
The heat of combustion of a substance is the amount of heat released when the substance is burned in a bomb calorimeter. The heat of combustion is typically measured in units of joules (J) per gram (g) of the substance. The specific heat of the calorimeter is also an important factor in determining the heat of combustion.
Calculating the Amount of Heat Released
To calculate the amount of heat released during the combustion of the sample of hexane, we need to use the following formula:
Q = mc螖T
where Q is the amount of heat released, m is the mass of the calorimeter, c is the specific heat of the calorimeter, and 螖T is the change in temperature of the calorimeter.
Given Data
- Mass of the sample of hexane: 0.580 g
- Mass of the bomb calorimeter: 1.900 kg
- Specific heat of the calorimeter: 3.21 J/g路K
- Change in temperature of the calorimeter: 2.50 K
Calculations
First, we need to convert the mass of the calorimeter from kilograms to grams:
1.900 kg 脳 1000 g/kg = 1900 g
Next, we can plug in the values into the formula:
Q = mc螖T Q = (1900 g)(3.21 J/g路K)(2.50 K) Q = 15231.5 J
Discussion
The amount of heat released during the combustion of the sample of hexane is 15231.5 J. This value represents the amount of heat released when 0.580 g of hexane is burned in the bomb calorimeter.
Conclusion
In this article, we calculated the amount of heat released during the combustion of a sample of hexane in a bomb calorimeter. The amount of heat released was found to be 15231.5 J. This value can be used to determine the heat of combustion of hexane.
