What is the half cell reaction of ordinary dry cell?
An ordinary dry cell is pretty well answered by: Anode: Zn → Zn2+ + 2e- Cathode: 2NH4+ + 2MnO2 + 2e- → Mn2O3 + H2O + 2NH3
What kind current is produced by a dry cell?
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
What happens to a cell if too much water moves into the cell?
eventually the cells will dry out and die
Why the dry cell work when kept in sunlight?
A dry cell works when kept in sunlight because it is comprised of a metal called electrode or graphite rod. The sunlight helps the cell to maintained 1.5 volts and stored a charge of one coulomb.
How does the voltage measured across a dry cell ompare with the voltage drop measured across three bulbs in series?
The voltage measured across a dry cell is the total voltage output of the cell, typically around 1.5 volts. When three bulbs are connected in series, the total voltage drop across the bulbs will be the same as the voltage output of the dry cell. So, the voltage measured across the dry cell is equal to the voltage drop measured across the three bulbs in series.
What are the signs of chemical change in connecting the wire to the dry cell to form a closed circuit?
The wire and the dry cell are combined into one, therefore it forms a new subtance.
What happens if the long leg of LED is conected to a wire coming from the negative end of the dry cell?
The long leg of the LED is the Anode. Connecting the Anode to the negative end of the dry cell would bias the LED off. It would not illuminate. It may also destroy LED.
What three thing are needed to make electromagnet?
Iron, copper wire and dry cell batteries
What happens when neutral is bonded to ground wire most especially to dry type transformers?
fff
What happens to radio waves when the dry cells remove?
the radio tranmitted will be cut because they have none dry cell
What materials will made an electric circuit work?
a dry cell a resistor (a bulb maybe) wire switch
What will happen if you connect the wire to the dry cell again?
That depends on what happened the first time you connected the wire, and on how the wire was connected. There is insufficient information in the question to properly answer it. Please restate the question.
What happens when a used dry cell graphite rod is heated?
Nothing except that it gets hot
What happens at the anode and cathode of a dry cell?
Oxidation occurs at the anode ("an ox") and reduction occurs at the cathode ("red cat").See the Web Link to the left for the specific reaction in a dry cell.
Is dry cell means leclanche cell?
no lechlanche cell is not a dry cell.
Where is the energy source for a flashlight?
A dry cell; it contains chemical energy.A dry cell; it contains chemical energy.A dry cell; it contains chemical energy.A dry cell; it contains chemical energy.
What happens when a cell phone battery turns pink?
it means that it has been dropped in water but don't worry it is not damaged just dry it out.
