1. The problem statement, all variables and given/known data KHSO4 + KOH→ SO4 + H2O→ P2O5 + H2O→ BaO + H2O→ CrO + SO2→ C6H12O6 + O2 (excess)→ CH4 + O2 (limited)→ NH3 + CO2 + H2O → NH3 + HCl→ 2. Relevant equations Chemical equations 3. The attempt at a solution KHSO4 + KOH→ KOH + KHSO4 Does this stay the same? since the first ion for both molecules are K+? SO4 + H2O→ HSO3 + O2 This seems correct but just making sure. P2O5 + H2O→ P(OH)5 + H2O This seems entirely incorrect and I'm not sure how to do this. I think the H2O splits to H+ and OH- but then the O from P2O5 would seem strange to combine with OH-. BaO + H2O→ Ba(OH)2 What does BaO and H2O produce when reacted? CrO + SO2→ CrO + SO2 Both seem to have O for the second ion. C6H12O6 + 9O2 (excess)→ 6CO2 + 6H2O If this is correct, then good. Aside from that, what does excess mean? CH4 + 3O2 (limited)→ CO2 + 2H2O NH3 + CO2 + H2O → NH3 + HCO3 I really doubt this is correct but I don't understand how to do three or more reactants. NH3 + HCl→ NCl + 2H2 This seems strange. Also is does the hydrogen in NH3 have a charge of 1-? To sum it up, I'm not clear on how to determine the products from a given reaction, or understand the kind of reaction it is (synthesis, decomposition, displacements...). What is the way to understand which does what? Unless I am over thinking it. Another part is what products are formed if the first ions or second ions of compounds, for double displacement/replacement, are same? Edit: The purpose of these equations were for balancing the net ionic equations. Do I have to do acid-base reactions for it too?
