Explanation:
When a gas is collected over water, the total pressure is the sum of the pressure of the gas and the pressure of the water vapor.
Ptotal = Pwater + PN₂
PN₂ = Ptotal - Pwater = 730 torr - 23.76 torr = 706 torr
We can find the mass of N₂ using the ideal gas equation.
Answer: A. and
Explanation:
Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.
The standard reduction potential for aluminium and gold are as follows:
Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).
Here Al undergoes oxidation by loss of electrons, thus act as anode. Gold undergoes reduction by gain of electrons and thus act as cathode.
Anode :
Cathode :
Thus magnesium gets oxidized.
