Ideal Gas Law An archaeologist found a chunk of metal and send it to a chemical laboratory for analysis. Preliminary chemical analysis of the metal found it to be trivalent and reactive with strong acids. Henry, a laboratory analyst, took 0.194 g of the metal to determine its identity using the ideal gases experiment. The results of the experiment are reported as follows in his lab notebook: urururururun Determination of Unknown Metal Using Ideal Gas Experiment mass of unknown metal: 0.194 g barometric pressure (Pbar ): 745 torr Pressure of water vapor: 26.7 torr Temp.: 27 °C Volume of trapped gas: 148 ml height difference of water levels: 11.29 cm A. What is the pressure, in torr, of the dry gas? B. How much moles of hydrogen gas are produced by the reaction? Assuming that the strong acid was in excess. C. What is the identity of the unknown metal M? Assume that the metal is pure. Show your solution.

Hazard Analysis and Design in Chemical Engineering

Hazard is the intrinsic property of a material or process which harms the people, buildings, or environment. Health, safety, hazard, risk assessment, loss prevention, and environmental consideration play an important role while designing a chemical processing plant. Hazard is often confused with risk. Risk measures the magnitude of loss and injury of likelihood incidents or the consequence and frequency of incidents.
