Question 11
H

An aluminium-air cell produces a voltage from this reaction. Air enters the cell continuously. 4Al+3O2+6H2O→4Al(OH)3\mathrm{4Al + 3O_{2} + 6H_{2}O \rightarrow 4Al(OH)_{3}}4Al+3O2​+6H2​O→4Al(OH)3​

Which statement is correct?

[1]
A

Aluminium atoms lose electrons; the cell stops when the aluminium is used up

B

Oxygen molecules lose electrons; the cell stops when the oxygen is used up

C

Aluminium atoms gain electrons; the cell stops when the aluminium is used up

D

Aluminium atoms lose electrons; the cell runs for as long as air is supplied
