What may happen to a large (i.e., 30-50lb) container of trichloro-s-triazinetrione, or calcium hypochlorite, if it is left to sit in the water and muck remaining in a building after fire fighting efforts have ended, but clean-up will not begin for several days? The assumption here is that the plastic container has been compromised in some way by the heat of the fire and possibly creating cracks in the base or sides.
Given the reaction PCl5 goes to PCl3 and Cl2. Starting with PCl5, calculate the equilibrium mole fractions of all species at 500 kelvin and 1.00 bar
Aluminum metal dissolved in hydrochloric acid as follows: 2Al(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2(g)

The indicator propyl red has Ka = 3.3 × 10-6. What would be the approximate pH range over which it would change color?
Which orbitals on the chlorine and iodine atoms overlap in the formation of the covalent bond in I-Cl
A 45 kg person drinks 530. g of milk, which has a "caloric" value of approximately 3.0 kJ/g. If only 15% of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake?
Electrons can be used to probe the arrangement of atoms on a solid surface if the wavelength of the electrons is comparable with the spacing between the atoms
The carbon-14 in a living organism is constant until the organism dies, after which carbon-14 decayss with first order kinetics and a half life of 5730 years. Suppose a bone from an ancient human contains 19.5%of the C-14 found in living organisms..
