For predicting reaction products in chemical equations, I am not sure of what the subscripts would look like in the product side. I know the types of reactions, but when you predict the products, do the compounds need a net charge of zero? If the net charge of zero does not matter, would the subscripts in the products look the same in the reactants and just the coefficients are different? Thank you for your help in advance. Here are some examples as well:
__C2H2 + __O2 -> (<-Reactants)
(Products->) -> __CO2 + __H2O (<-my guess)
__LiOH + __Fe(NO3)3 ->
> LiNO3 + FeOH
The products that are shown in the example are my guess, so they may not be correct. I am also not sure how I would balance equations for combustion.
