Aluminium is obtained industrially by the electrolysis of aluminium oxide heated to high temperatures. the positive electrodes used in electrolysis of aluminium oxide are made of carbon

these electrodes slowly disappear over time as they are converted to a gas

suggest the identity of this gas

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4
