Regarding the formula AI2 O3 which of the following is accurate

English
1 answer:
schepotkina [342]3 years ago
5 0

D. The subscript 2 indicates that two atoms of aluminum are present in the substance.

<u>Explanation:</u>

Actually, the formula of alumina is  Al₂O₃

The subscript 2 tells us that there are 2 Al (Aluminum) atoms, and the subscript 3 says that there are 3 oxygen atoms, so D is the accurate statement.

Choice A is wrong as 3 is not the coefficient, and it is a subscript.

Choice B is wrong since the subscript 2 meant  for the aluminium atoms,  and not the oxygen atoms.

Finally, choice C is also wrong since the symbol Al refers to the metal aluminium, and not the oxygen.

And no birds sing.4

Pale warriors, death-pale were they all;

They cried—"La belle Dame sans Merci

Hath thee in thrall!"40
