What are some chemical formulas for compounds?
1 answer:
Hello there!
First, we need to know what compounds are.
Compounds "are pure substances that are made up of two or more elements that are chemically combined in fixed mass ratios."
Now we need to understand what chemical formulas are.
The compounds have a chemical formula which tell us that
a) the elements that are present in the compound
b) the ratio of these elements in the compound
What are some chemical formulas for compounds?
Well, we start with water. The chemical formula for water is H2O
When we go back to the definition of compounds, it says it is when a pure substance that are made up two or more elements. So, whatever is a pure substance and it's made up of two elements. These elements are Hydrogen and Oxygen. And keep an mind that water is made up with metal plus non-metal.

Here are one more chemical formulas for compounds
Sodium Chloride = NaCI

Your answer is 
but if you are looking for some explanation check description below :)
Diphosphorus trioxide formula is:
Di stands from 2 atoms of something, in this case we have 2 atoms of Phosphorus.
Trioxide means that we have 3 atoms of oxygen in this substance that's why we have:
And water is just
Unbalanced formula is:
Now we need to balance this equation
On left hand side we have 2 atoms of Phosphorus, on right hand side we have just one atom of Phosphorus, that's why we need to put 2 before
Now we need to count all atoms of oxygen and hydrogen and make it equal on both side.
So we need to put 3 on left hand side before water to make this equation balanced.
That's why correct answer is:
