Topic: Synthesis meaning chemistry
June 25, 2019 / By Jesse Question:
For school I am supposed to finish and balance chem equations. I know how to identify what kind of equation they are but I don't understand how the charges work? Please help. Heres one of the questions I have to do.
H2 + O2 -->
I know this equation is a synthesis equation so do you add them together like this?
H2 + O2 --> H2O2
And if so, then what do I do with the charges? (2 and 2) Do they stay there or do they cancel each other out?

The 2 (subscript) in H2 and O2 are NOT charges. They are the number of atoms present in a molecule. So H2 , which is a molecule has 2 atoms of H and similarly for O2 molecule which is composed of 2 oxygen atoms. As for your question, NO you cannot simply add them together. What I am gonna do is give you the answer to the question:
2H2(g) + O2(g) --> 2H2O(l)
The (g) and (l) means gas and liquid respectively.
You seriously need to study darling !!!! If you need any help, you can drop a mail....:)
