The reaction shown below is used in the production of steel. it is an exothermic reaction. an engineer thinks that by finding the correct catalyst, he can reduce the amount of energy released by the reaction. will his plan have the desired effect? explain your answer. fe3o4(s) + 4c(s) → 3fe(s) + 4co(g

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.

By what primary heat transfer mechanism does the sun warm the earth?
