Balancing chemical equations polystomics and H2O + CO2/NO2

[AMan24]

Homework Statement

(NH4)2S + HNO3 = ? - main problem

LiHCO3 + HClO = ? - check just in case problem

Homework Equations

None.

The Attempt at a Solution

I think it has to equal H2S + NH4NO3
Or H2S + NO2 + H2O

I've used multiple online chemical balancing calculators and they all give me different answers.

There's also the 2nd problem which I'm 99% sure on but just to be sure. I think it equals

LiClO + H2O + CO2

I think it has to equal H2S + NH4NO3

Sounds reasonable as a first approximation (although it depends a bit on the level - sulfides can be oxidized by the nitric acid, making things more complicated). Note - correct identification of the products doesn't mean the reaction equation is balanced.

Reaction of the carbonate with acid is very similar. No, there is no LiClO produced (actually hypochlorite is typically written as LiOCl).

I meant to write LiHCO3 + HOCl = LiOCl + H2O + CO2
Instead of LiHCO3 + HCl = LiOCl + H2O + CO2

And thanks for the help

This one is actually much more complicated, as HOCl is a weak acid. No idea what kind of answer is expected (on some level the one you gave can be OK, even if technically it is not correct). But - unless you have already learned about equilibrium calculations - you shouldn't worry.
