The initial pressure of a mixture of and an excess of in a rigid vessel is 0.484 atm. A catalyst is introduced. After the reaction reaches completion, the temperature is restored to its initial value. The final pressure in the vessel is 0.286 atm. What was the mole fraction of in the original mixture?

8. (10 points) For a memory system with a 30-bit address bus and 32-bit data bus: a) How many memory addresses (locations) does the memory system have? Show your work. b) What is the word size of the memory? c) What is the memory capacity? Show your work. d) What additional signals (two of them) are typically needed to control the memory system if the memory is asynchronous (unclocked)?
