Problem 1Problem 1: A team of consultant engineers needs to monitor and identify potential leakages in a prototype CSTR (continuously stirred tank reactor) system. After a few weeks of operation, leakage (FluidX) was detected through one of the valve manifolds. From preliminary tests, Fluid X can be eithermethane, ethane, propane, ethylene or cyclopentane. In order to fifix the problem, the team mustfifirst identify the flfluid that leaked from ...

In this lab you will research the chemical formulas and structure of the 10 common rock forming minerals, along with some new minerals introduced here. You will need to find out: · What is the chemical formula of the mineral? · You should write this like this – Water = H2O · The % oxides in each one (see below for methodology) Calculating % oxides for elements in a mineral Chemical analysis of minerals very ofte...
