Which set of coefficients correctly balances the following chemical equation?
___H2SO4 + ___ LiOH arrow ___ Li2SO4 + ___ H2O

1, 2, 1, 2
This would balance it right??

Answer 1

Also which one of these is balanced?

2H2SO4 -> H2O + 2SO2
N2 + H2 -> 2NH3
2Cu (s) + O2 (g) -> 2CuO (s)
Na3PO4 + 3AgNO3 -> NaNO3 + Ag3PO4

I tried all of them my best guess is 2Cu (s) + O2 (g) -> 2CuO (s)
