an element crystallizes in a body-centered cubic lattice. the edge of the unit cell is 3.17 a and the density of the
A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas.
When heated to 350 at 0.950 , ammonium nitrate decomposes to produce nitrogen, water, and oxygen gases.
Calculate the concentrations of all species in a 1.73 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4× 10-2 and Ka2 = 6.3× 10-8.
