    Engineering Maximizing Battery Voltage in a Complex Combination Circuit

    The Hightest I2R would be the resistor with 50\Omega right? I got an equivalent resistance of the whole circuit of 5940/47=126.38\Omega. I found the current in which the power of highest resistance would be less than 1.2W. So, I2R<1.2 I<\sqrt{}1.2/50=0.155A Then I found the \epsilon using...

    Engineering Maximizing Battery Voltage in a Complex Combination Circuit

    So dude, was your answer right? I'm sort of in the same predicament as you right now lols

    Electrochemistry metallurgy mass calculation

    Good guess on the chemical equation...but this type of reaction is smelting of a metal oxide via a heat furnace, which is done industrially. The products for this reaction is not CO2 but is CO, carbon monoxide. The reaction should look like: ZnO+C>Zn+CO You need to take mole ratios of what is...

    Why Does Chlorine Gas Form at the Anode in the Chlor-Alkali Process?

    Thx for your explanation, I think I understood that but could anybody explain why it happens that Oxygen has a much higher overpotential and could somebody clarify what overpotential means in the context of this question?

    Why Does Chlorine Gas Form at the Anode in the Chlor-Alkali Process?

    Redox reaction...with a twist! In the chlor-alkali process OH–(aq) and Cl2(g) are produced by the electrolysis of a saturated solution of sodium chloride. Explain why chlorine gas rather than oxygen gas forms at the anode. The solution to the question has the word "Overpotential" and I...

    Why Does Oil Float Above Water?

    ummmm it has been 6 years later and i don't know if my response will mean anything to the people but i thought i would put it here anyway...part of your understanding lies in chemistry. Oil is composed of long chain hydrocarbon molecules so you would think it is more dense than water in that...
