Convert kilojoules to watts?
The energy in kilojoule cannot be converted to the power in watts. The time is missing. But you can convert kilojoules to kilowatthours (kWh). Scroll down to related links and look at "Energy Converter".
If it takes 436kJ to break a bond how many kilojoules are released when the same bond is formed?
The required energy must be higher than the bond energy.
How much heat energy in kilojoules is required to convert 68.0 g of ice at 18.0 to water at 25.0?
It requires 1 calorie to increase 1 mL of water by 1 degree Celsius. In 68 grams of water, there are 68 mL. The change in temperature is 7 degrees, so 476 calories are needed. 1 calorie has 4.184 joules, hence 1.992 kJ are needed.
How many calories are required to convert 17g of ice at 0 degrees Celsius to liquid water at 32 degrees Celsius?
The simple beginning is that the definition of a calorie is "the energy required to raise the temperature of 1g of water 1°C." Therefore, the energy required to raise 17g of water 32°C: 17*32=544 cal. However, the question asked about ice. There is an extra bit of energy required for the change of physical state. The energy required to convert 1 gram of ice at 0°C to liquid water at 0°C is called the "latent heat" and is equal to about 80 cal. To convert 17g of ice, we multiply this together: 17g * 80cal/g = 1360 cal. So, we add this energy required for the change of state to the energy required to raise the listed quantity to the required temperature and we get 544 cal + 1360 cal = 1904 cal, assuming no heat is lost to the environment. I hope this clarifies some things.

What is the chemical formula for kilojoules?
Kilojoules (kJ) is unit of energy, not a compound.
What is The thermal energy of a solid?
The thermal energy of a solid or a volume of liquid is the specific heat of a material multiplied by the object's mass and temperature (absolute). I.E. 1 kg of water at 27 degrees C: specific heat of water is 4.186 Kilojoules per kilogram-degree Celsius. Multiply that by the mass and the absolute temperature (Degrees Kelvin, or 273.15 + degrees Celsius) to get the thermal energy in kilojoules
If it takes 436kJ to break a bond how many kilojoules are released when the same bond is formed?
The required energy must be higher than the bond energy.

What are the units for measuring energy?
Kilojoules (Kj)
What is energy measred in?
Mostly measured in kilojoules
What is 58 inches in kilojoules?
You are mixing up different types of measurements. Inches is a length. Kilojoules is a measure of energy.
