<span>S + O2 = SO2
1 mole S ------------- 1 mole SO2
( moles S ) --------- 15.0 moles SO2
moles S = 15.0 x 1 / 1
moles S = 15.0 / 1
= 15.0 moles S</span>
Answer:
its electron
Explanation:
i dont have an explanation but i hope you get it right
D) Physical Change, I would argue, because you can reverse this change by boiling off (evaporating) the water. But there are arguments for both physical and chemical change being what occurs.
A physical change results in a change of the material's appearance, but no new chemical products result. A chemical change involves a chemical reaction, with new substances produced as a result of the change.
Given the data from the question, the number of aluminum atoms in aluminum oxide, Al₂O₃ is 2 (Option B)
<h3>Composition of aluminum oxide, Al₂O₃</h3>
From the formula of the compound, Al₂O₃ we see that the compound is composed of
<h3>How to determine the number of aluminum atoms </h3>
- Formula of compound = Al₂O₃
- Number of oxygen atoms j= 3 × 1 = 3
- Number of aluminum atoms = 2 × 1 = 2
From the above, we can conclude that Al₂O₃ contains 2 atoms of aluminum.
