There are approximately 560 kJ in 4 Weetbix biscuits.
10,267 kJ are needed
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.

The heat of combustion of sucrose is 3840 kJ per deg.mol and Molecular weight of sucrose is 342 mol -1.so the calorific value of sucrose is 11.228 kJ/deg.gm , provided the temperature is kept constant.
To determine how many moles of NH4NO3(s) must be dissolved to absorb 73.0 kJ of heat, you need to know the heat of solution (enthalpy change) for NH4NO3. The dissolution of NH4NO3 is typically endothermic, with a heat of solution of about +25.7 kJ/mol. By dividing the total heat absorbed (73.0 kJ) by the heat of solution (25.7 kJ/mol), you find that approximately 2.85 moles of NH4NO3 must be dissolved to absorb that amount of heat.
per 100g, 1480 kj
About 1/4 of a calorie per kJ
No, it's still a Weetbix.
One gram of protein contains about 4 kilojoules (kJ) of energy.
Kj Saifullah is 4' 7".

8,000 to 10,000 kJ.

About 4 kilocalories per gram or 4 Calories/g or 17 kJ/g. Calories are confusing because of stupid standard with uppercase C, prefer kJ !
A KJ is a unit of work, whereas a KN is a unit of force. Work is force times distance, so the two units are related by the expression 1 KJ = 1 KN*m. So, if you want to know how many KJ are in 1 KN, you need to know the distance your force caused your object to travel. For example, if 1 kN caused something to travel 4 m, then (1*4) = 4 KJ of work were done on that object. Or something like that :)
