Consider what happens when a sample of the explosive TNT is detonated. (a) Is the detonation a spontaneous process? (b) What is the sign of q for this process? (c) Can you determine whether w is positive, negative, or zero for the process? Explain. (d) Can you determine the sign of \(\Delta E\) for the process? Explain.
A 1.724 M solution of a compound in water has a density of 1.281 g/mL at 20°C. The compound has a molar mass of 62.30 g/mol.
