We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.
<h3>How do we know that displacement and time determine velocity?</h3>
We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is
, meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.
Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

Answer: C9H11O3N
Explanation:
The percentage by mass of each element is divided by its relative atomic mass. The lowest ratio is now observed. Each ratio is now divided by this lowest ratio and approximated to whole numbers. All these are shown in detail in the image attached.
<u>Answer:</u> The given amount of iron reacts with 9.0 moles of
and produce 6.0 moles of 
<u>Explanation:</u>
We are given:
Moles of iron = 12.0 moles
The chemical equation for the rusting of iron follows:

By Stoichiometry of the reaction:
4 moles of iron reacts with 3 moles of oxygen gas
So, 12.0 moles of iron will react with =
of oxygen gas
- <u>For iron (III) oxide:</u>
By Stoichiometry of the reaction:
4 moles of iron produces 2 moles of iron (III) oxide
So, 12.0 moles of iron will produce =
of iron (III) oxide
Hence, the given amount of iron reacts with 9.0 moles of
and produce 6.0 moles of
