If you dont know the values then can you tell me the conductance of which solution should be higher?
Also can you tell me the conductances of ZnSo4 and CuSo4 for 0.5M, 0.01M, 0.1M?
Can you tell me the method to find the conductances?
Thank you very much

...ie, will we ever be able to travel the way they do, or get lost in the delta quadrant lol!

My friends always laugh at me lol because i am fascinated by space and love star trek!!

Dont think the specs and braces helped when i was younger either lol!

take a test, or as many as you like, and tell me how you scored. tell me which test you took and what your score was for each one.

example:

south america - 23 / 39
europe - 38 / 43
asia - 37 / 49

etc, etc... be sure to tell me not only the number of points you earned, but how many it was out of too!


also, please tell me where you're from.

I want to use the Pogrammable Logic Controller in a vehicle application project, but the vehicle has a 12volt battery, and the PLC requires 24volt DC. I don't want to use an inverter to get up to 240v AC, and then a rectified transformer to get back down to 12v DC, there must be a way to get from 12v DC to 24v DC by a more direct route. Does anybody know of a workable and cheap solution? PLCs consume very little power themselves, their inputs and outputs can use the vehicle 12v DC.
