For number 20, why is C not right? Isn't another part of equilibrium is that concentrations of reactants and products are no longer changing?

No longer changing means they became constant but not equal

mam, for question 9. it was 2H2S, shouldn't we multiply Mr of H2S with 2?

In question 9 the second step why do we divide by 2 ?
@DrMonaSeif Жыл бұрын
Because the ratio is 2 ( H2S) : 3 (O2), so to get the number of moles of oxygen you cross multiply, in other words multiply by 3 then divide by 2.
