2.Hi. If 2 electrodes, both made of pure silver, were used as the cathode and anode, in a solution of ...

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.

4.I am not sure about an experiment that I need to do. I had an idea before but my teacher ...

do it and to be more specific. However. I am not sure if my solution is correct. My original experiment question was to "Investigate how many loops of wires around a nail affect the strength of electromagnetism". "How many loops of wire around a 10D nail does it take for a quarter to be lifted? ". My teacher said the first one wasn't correct because I need something more quantifiable than the strength of electromagnetism. Also, he said quarter one wouldn't work because the quarter is not an actual dependant variable. I wanted to see if I could do this question instead, "Investigate how many paper clips a 10D nail wrapped 50 times with wires can pick up." and discuss the voltage and amps of this process.

the light also changes how her art work appears visually. This type of art work is known as chromatic manipulation Mihaela powers her circuits using four cells with a voltage of 6.0 V each. To protect the LEDs, the cells must be in series with a 10 Ωresistor.Draw a circuit with which Mihaela could light her artwork using three LEDs. Each LED must be able to be turned off individually, so the colour output can be selected.
