sodium hydroxide, with 5 volts applied to the circuit to produce hydrogen and oxygen, via electrolysis, would the pure silver electrodes react with anything or be completely unreactive? Im guessing the electrodes will be unreactive, but since electricity is part of the equation, it seems possible for there to be reactions between the silver metal and maybe oxygen or something else depending on the voltage level, but to be honest, i never had a chemistry class, so i dont really know what might happen at all besides guessess i could make according to the little knowledge about all this i got here and there over the years. So here i am, in hopes of a person who does know what will occur.

work easier. I have several problems: a) I dont have any ideas on machines. B) I need help really in general. So far i have 7 examples them being a wheelbarrow, a pulley, a ramp, an ax(e) and a hockey stick. I was wondering if you could help me explain how they make work easier. Also, I'm having trouble identifying the input and ouput forces on these machines. Please help. Btw, im grade 8.
