Calculate DOI and identify the following structure as determinate, indeterminate, or unstable. Your answer is DOI if determinate or indeterminate and "-1" if unstable (the answer for any unstable structure is "-1" irrespective of the value of DOI). ז???? Type your answer..

Lead has one of the highest densities of all the pure metals at 11,240 kg/m^3. What is the density of Lead in units of Lin/in^3?

The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH – log[H*] where H+ is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 2.51 × 10-4 mol/L, the pH is b. If the pH of a solution is 3.433, the hydrogen ion concentration is mol/L.
