The table below shows standard enthalpy changes of formation:
CO2(g) = -394
NH4NO3(s) = -366
H2O(g) = -242
What is the enthalpy change for the following reaction?
2NH4NO3(s) + C(s) + 2N2 (g) + 4H2O(g) + CO2(9)

Look at the bean data from days 4–6. use these data to explain how natural selection changed the number of dark red walking beans over time. writing part

What is the volume occupied by 10.0 dm3 of gas at standard pressure after it has been compressedat constant temputure to 500.0 kpa?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
