Hiii! Question for those of you who know anything about crystals/stones/rocks.
I have a stone that looks a lot like smoky quartz, but with more of a black tone. The stone definitely is not black quartz, seeing as it isn't as dark.
I read that smoky quartz is brown, and all pictures of smoky quartz are too brown to be the same as my stone. Does anyone maybe know what it could be? (Camera quality sucks, sorry)

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
