Consider the following voltaic cell:(b) In which half-cell does oxidation occur?
damaskus [11]

At the anode, half-cell oxidation occurs in a voltaic cell.

<h3>Voltaic Cell Principle</h3>

A voltaic cell generates electricity due to the Gibbs free energy of spontaneous redox processes occurring inside the cell, which is the basis for the voltaic cell's operating principle.

Two half-cells plus a salt bridge make up the voltaic cell. An electrolyte-immersed metallic electrode is present on each side of the cell. These two half-cells are wired together to form a connection to a voltmeter.

<h3>Voltaic Cell Parts</h3>
  • Copper makes comprises the cathode of a photovoltaic cell. This electrode serves as the cell's positive terminal, where reduction takes place.
  • Anode: Zink metal makes up this electrode. It creates the cell's negative electrode, where oxidation takes place.
  • Oxidation and reduction are divided into two discrete parts in two half-cells.
  • Salt Bridge: It contains the electrolytes needed to finish the circuit in the voltaic cell.
  • The flow of electrons between the electrodes occurs via the external circuit.

When the temperature of a rigid hollow sphere containing 685 L of helium gas is held at 621 K, the pressure of the gas is 1.89 x
Leno4ka [110]
You have to use the equation PV=nRT.
P=pressure (in this case 1.89x10^3 kPa which equals 18.35677 atm)
1V=volume (in this case 685L)
n=moles (in this case the unknown)
R=gas constant (0.08206 (L atm)/(mol K))
T=temperature (in this case 621 K)
with the given information you can rewrite the ideal gas law equation as n=PV/RT.
n=(18.35677atm x 685L)/(0.08206atmL/molK x 621K)
n=246.8 moles

if you take a dried out white rose and place the stem in food coloring, will the rose turn the color you put the stem in
cricket20 [7]

Answer:

Yes, this is true. The reason is that the flower transpires and sucks the water in and distributes it as much as it can. You can also flip it upside down and hang it with petals down , allowing the liquid to enter the flower and then retaining color for longer periods of time and having more color.
