Solubility constant for is 8.1E-12. When is in equilibirum with its ions in saturated solution. The concentration of silver ions.
A balloon containing 34.5 L of a gas at room temperature (25.0 oC) is heated to 73.5 oC. What is the volume of the balloon at this new temperature?
How will you prepare 10 mL of 0.050 M HCl from a 0.10 M solution of HCl? Assume that you use a 10-mL graduated cylinder (in which volumes can be read to the nearest 0.1 mL).
Niobium (Nb) has a BCC cubic crystal structure, and an atomic radius of 0.144 nm. a) Calculate the edge length (d) of a niobium unit cell:
The decomposition of ozone in the upper atmosphere is facilitated by {\rm NO}. The overall reaction and the rate law are O3(g) + O(g) = 2 O2(g) Rate = k [ O3}][ NO]
