Question
Chapter 14, Problem 14E
Interpretation Introduction
Interpretation:
The Leclanche dry cell or inexpensive battery is to be described by using a chemical equation. An alkaline battery is different from the Leclanche dry cell, is to discussed.
Concept introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.
Leclanche dry cell, is produced in great quantities and is widely used in devices such as flashlights and portable radios.
The Leclanche dry cell or flashlight battery is called ‘dry’ because there is no liquid present.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)
Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.
