How do I Finish and Balance these Chemistry equations? 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? Thanks!

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....:)

First at least try to write out your equations yourself. You can only balance them when you have both sides to the equaiton. We can help you if don't get it, but I don't really want to do your homework for you.

a. H2SO4 + NaOH --> It's a double replacement/neutralization reaction. You should be able to figure this out from the fact that you have two compounds. The only one of the 5 basic reaction types that has two compounds reacting is the double replacement reaction and all the reactants must be aqueous or else a reaction can't occur since there'd be no ions to react. 2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l) b. N2 + H2 --> N2 + 3 H2 ---------> 2 NH3 This is a synthesis reaction

Lithium sulfide is a salt of the vulnerable acid hydrogen sulfide. once you upload a more desirable acid to one in each and every of those salt, the more advantageous acid displaces the weaker acid from salt yielding solid acid salt and organic vulnerable acid. which potential lithium sulfide reacts with nitric acid to lithium nitrate and hydrogen sulfide. through its unfavorable solubility hydrogensulfide is developed as gasoline. Balanced reaction equation is: 2HNO?(aq) + Li?S(aq) ? 2LiNO?(aq) + H?S(g)
