What determines the Subscript on an element in a chemical equation?

For example #1 is Sulfur+Oxygen-> Sulfur Dioxide. The answer is S8+8O2 -> 8SO2, but why 8? Why 2 (The subscript 2)?


Helppp.

Oxygen is a diatomic element. H2, O2, N2, etc they're naturally attracted to the same element, like O2 is the air we breathe.

It's acidic compound of the sulfur and it's strong organic black matter is so powerful than when mixed with oxygen you could rule a small island of native potato people

Why is S8 though?

Where can I look that up; am I supposed to naturally know which elements are diatomic or like???

It's 8SO2 because there are 8 Sulfurs and Oxygen is in a naturally diatomic states so it appears as O2

Balanced equation: 8 S (s) + 8 O2 (g) -> 8 SO2 (idk the state)


The 8 being the variable you multiply the equation by

No no, 8 is Sulfurs subscript on the left hand side of the equation: Why is it the subscript.

Oxygen is O2.
Oxygen in nature is usually not found by itself.

S8 + 8O2

s8=8s

8s+8o2
Factor the 8
8(s+O2)

When doing chemical equations, both sides have to be equal.

S8+8O2 -> 8SO2


Oxygen will always be O2, like igoingtowin said.

The 8 is there because there are 8 SO2. This balances the equation.

the 2 in your question represents the number of atoms of that element

So

in "Sulfur Dioxide"

the molecular formula, 8SO(2), means there are 2 oxygen atoms to create and oxygen molecule (oxygen is O2)

im assuming the 8 has something to do with the isotope but im probably wrong so

yeah but if the O2 coincides with the 'Dioxide', Di meaning two, Oxide representing oxygen

Because I forgot the word for it, but the Oxygens bond to eachother because they want to bond so much meaning its not actually O(sub 1) its O(sub 2)

8 on the left hand side is not a subscript. It shows how many of the compound or element or whatever there are.


So if you have 8O2, that means you have 8 oxygen molecules.

I just finished Chem101 in college this past semester

Balanced equation: 8 S (s) + 8 O2 (g) -> 8 SO2 (idk the state)

The subscript is 8 because the questions states that's what it is, I would think.

No, you would have 8 O2 molecules, but 16 Oxygen molecules

The answer is

S8+8O2->8SO2

The 8 on the RIGHT side of the S is a subscript, I don't understand why that's there.

The eight is showing how many SO2's you have.

You have 8 SO2's.

Ohhhh, I see.

The 8 on the right side of the S shows how many Sulfur atoms there are.

Helppp."

coefficients denote the amount of occurrences of the object, so for example in the end results there are eight molecules of SO₂

subscripts denote the amount of an element in a molecule, as such there are 2 oxygen atoms in every molecule of SO₂

How do I know there's 8.

I just don't understand how I'm supposed to find that. Usually it's given.
