What are the chemicals in dry cell batteries and what is their purpose?
dry cells don't have liquids inside but they do have some sort of a paste of zinc chloride and ammonium chloride dissolved in water. The positive terminal is usually a carbon rod or graphite rod surrounded by a mixture of manganese dioxide and carbon powder. the negative terminal is the packaging, and is made of zinc.you should just look it up on wikipedia, and you will save yourself a lot of time...
What are the chemicals in dry ice?
Carbon dioxide. Dry ice is made of nothing but carbon dioxide.
Why is a cell referred to as a dry cell?
There is dry cell and wet cell. A dry cell has not fluid around it. A wet cell is surrounded by fluid of some sort, usually acid.
Is carbon dioxide and dry ice 2 different chemical of the same state?

What chemicals are in a chemical battery?
A standard dry cell battery is made from zinc and can filled with a paste of zinc chloride and ammonium chloride. At the centre is a graphite rod surrounded by a paste of manganese dioxide.
What chemicals are in a standard AAA battery?
A standard dry cell battery is a zinc can filled with a paste of zinc chloride and ammonium chloride. At the centre is a graphite rod surrounded by a paste of manganese dioxide.
Describe briefly the method a dry cell battery uses to produce voltage?
A dry cell battery uses two electrodes made of dissimilar metals inserted in a paste like electrolyte. The container of a dry cell battery is made of zinc which is the negative electrode. The carbon rod in the middle of the dry cell battery is the positive electrode. The space between the electrodes is filled with an electrolyte usually manganese dioxide paste. the paste causes a chemical reaction between the carbon rod and the zinc case.

The shortage of electrons exists at the blank termnal of a dry cell?
The shortage of electrons exists at the positive terminal of a dry cell. The function of the negative terminal is to pick up the electrons.
Would dry ice function the same way as liquid nitrogen in the balloon experiment?
No, because dry ice is a solid and you cannot place a solid inside a solid. If it was liquid carbon dioxide (as opposed to dry ice, solid carbon dioxide) then it would behave similarly.
Function of dry or wet cells?
A 'wet' cell uses a conducting liquid called an electrolyte; a 'dry cell uses a conducting gel called an electrolyte. So, really, a 'dry' cell is simply a non-spillable wet cell! They both store electrical engergy for use later on.
What are the chemicals in dry ice?
Carbon dioxide. Dry ice is made of nothing but carbon dioxide.
Is dry ice water?
Dry ice is solid carbon dioxide (CO2).
Is dry cell means leclanche cell?
no lechlanche cell is not a dry cell.
What is the common name for dry ice?
Dry ice IS the solid form of carbon dioxide. And "dry ice" IS the common name for the solid CO2. So the question should be "What substance is the common name Dry Ice used for ? "
