What is an experimental technique that could be used to determine the enthalpy of combustion of magnesium directly? Not using Hess's Law!!
any help is appreciated :)

Use a bomb calorimeter... or some kind of calorimeter... I'm just guessing; hopefully the calorimeter idea isn't stupid! Good luck.
thanks :)
No problem!
A 12.48g sample of an unknown metal, heated to 99'c was then plunged into 50mL of 25'c water. The temperature of the water rose to 28.1'c. The specific heat of water is 4.184J/g.
1. How many joules of energy did the water absorb?
2. How many joules of energy did the metal lose?
3. What is the heat capacity of the metal?
4. What is the specific heat of the metal?
