Regarding the formula AI2 O3 which of the following is accurate

English
1 answer:
schepotkina [342]3 years ago

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.

Which best describes a strong research question?
Rufina [12.5K]

The first answer is correct (A).

A strong research requires, first and foremost, a questioning, a question that seeks an answer. The act of searching is driven by the search for answers. Necessarily, the scientific methodology suggests that the researcher has a hypothesis for that question.

This hypothesis is the guiding principle of the research, and is based on evidence and the researcher's experience and knowledge. However, finding the search answer may or may not confirm the hypothesis.
