#1)# What is the change in internal energy of combustion in #"kJ/mol"# for a bomb calorimeter whose heat capacity is #"3024 J/"^@ "C"# that has raised in temperature by #1.2910^@ "C"# due to the combustion of #"0.1575 g Mg"#? Also help with one more?
#2)# If the change in enthalpy of reaction for #"2NO"(g) + "O"_2(g) -> 2"NO"_2(g)# is #-"114.6 kJ"# , then what amount of heat is produced when #"23.000 kg"# of #"NO"_2(g)# is generated?
I would have asked this in two separate questions...
The amount of internal energy released from the bomb out to the water is:
Thus, the internal energy released from the magnesium is:
That then acts as a conversion factor. The heat PRODUCED asked for is the magnitude, not a negative value. So,

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
