How much energy in 100g of rice?
100g of rice provides about 130-150 calories, which is equivalent to approximately 500-600 kJ of energy. The exact energy content can vary based on the type of rice and cooking methods used.
How many kj does 1 gram of protein contain?
One gram of protein contains about 4 kilojoules (kJ) of energy.
How much energy must be transfered by heat to the engines surroundings if 2.5 kj is transfered by heat to the engine with 8.5 percent efficciency?
There are two possible answers to this question - depending on how you read it: If 2.5 kJ is converted to work but that only represents 8.5% efficiency, then the heat transferred to the surroundings will be 2.5(1-0.85)/0.85 = 26.9 kJ On the other hand, if 2.5 kJ is the total energy coming in and only 8.5% of it is converted to work, then the other 91.5% is lost to the surroundings: 2.5(1-0.085) = 2.2875 kJ
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10 2 kJ of work on the system What is the change in internal energy of the system?
3.0 x10 1 kj A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10³ kJ of work on the system. What is the change in internal energy of the system? --- 224 kj
Ethanol is a fuel that can be made from corn How many kJ of heat energy are released when 3.00 kg of ethanol are burned?
When 3.00 kg of ethanol is burned, approximately 107,000 kJ of heat energy is released. This calculation is based on the energy content of ethanol, which is approximately 29 kJ/g when burned.

How much heat is needed to vaporize 100g of water at 100 degrees C?
Heat of vaporization at 100 degrees C is 40.65 kJ/mol. 100g water * 1mol/18.015g = 5.55 mol 40.65*5.55 = 225.6452956 = 226 kJ if three sig figs.
How many kj does 1 gram of protein contain?
One gram of protein contains about 4 kilojoules (kJ) of energy.
How many Kilojoules in a 100g of sugar?
A 5 ml teaspoon (4 g) of sugar contains 68 kilojoules (kJ).
How much kj per 100g in pasta?
60 grams of dry pasta will cookout to weigh about 100 grams
How many kilojoules or energy are required to vaporize 5 g of ethane?
The heat of vaporization for ethane is approximately 16.7 kJ/g. Therefore, to vaporize 5 g of ethane, the energy required would be: 16.7 kJ/g * 5 g = 83.5 kJ.
What does kJ measure?
Energy.
How many kilo-joules are associated with the formation of 2 moles of HBr(g)?
The standard enthalpy of formation of HBr(g) is -36.2 kJ/mol. For 2 moles of HBr(g), the total energy associated with its formation would be 2 * -36.2 kJ/mol = -72.4 kJ.
