New employees at Avondale Industries’ unmanned systems production line in Denver, CO, participate in employee training under the direction of the training and development department, but the line managers conduct the actual training. During the last two trainings, the line managers cut the sessions short and explained that the employees would receive better training while working on the production line. The trainer responsible for the program understood the line managers’ viewpoint about developing skills used on the line but needed them to see that training should provide more than just developing those specific skills. Which of the follow statements best explains why training should provide a longer-term view than just teaching line workers the skills needed to perform satisfactorily in their current jobs?     Giving line workers expanded training helps them understand more than specific skills; it also helps them become more confident contributors.   Training with a…

A chem....rking as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of tetrahydrofuran, chloroform, ethanolamine, diethylamine, and pentane. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density tetrahydrofuran -1 0.89 gmL -1 1.5 g•mL chloroform ethanolamine 1.0 g•mL¯ diethylamine - 1 0.71 g•mL pentane - 1 0.63 g mL Next, the chemist measures the volume of the unknown liquid as 1062. cm° and the mass of the unknown liquid as 1.08 kg. Calculate the density of the liquid. Round your answer to 3 significant digits. 1 g•mL Given the data above, is it possible to identify the liquid? yes no tetrahydrofuran chloroform If it is possible to identify the liquid, do so. ethanolamine diethylamine pentane
