For emample, if you are dealing with Copper and Zinc, you first take the half equations Cu2+ + 2e- --> Cu +0.34 Zn2+ + 2e- ---> Zn -0.76 then, you decide which one is reduced and which one is oxidized, the one with the more positive voltage is reduced, so in this case the copper is reduced. the overall reaction changes to Zn- ---> Zn2+ + 2e +0.76 Cu2+ + 2e- --> Cu +0.34 ---- Zn + Ni2+ ---> Ni + Zn2+ + 0.5 you add the voltages and get 0.5 as an experimental voltage

How do you calculate current and voltage passing through light globes?

To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.

What is the percent yield if the actual yield from this reaction is 265gg and What is the percent yield if the actual yield from this reaction is 265gg?

To calculate the percent yield, you need both the actual yield and the theoretical yield. The formula for percent yield is: [ \text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100% ] Since the theoretical yield is not provided in your question, I cannot calculate the percent yield. Please provide the theoretical yield for an accurate calculation.


How many amps are in 2000 watts?

To calculate the amperage, you would need to know the voltage of the system. If you assume a standard voltage of 120V, you can calculate the amperage by dividing the wattage by the voltage: 2000 watts / 120 volts = 16.67 amps.


Ow do you calculate amperage with watts and volts?

You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.

Can you calculate power by multiplying voltage and current?

Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).

What is the percent yield for the reaction below when 544.5 g SO2 and 160.0 g O2 produce 382.0 g SO3?

Percent yield = (actual yield ÷ theoretical yield) × 100% Calculate the moles of SO2 and O2 used, then determine the limiting reactant. From the limiting reactant, calculate the theoretical yield of SO3. Compare the actual yield to the theoretical yield to calculate the percent yield.
