Complete and balance the equation for the reactions, each of which could be used to remove hydrogen sulfide from natural gas
(a)ca(oh)2 + h2s?
(b)na2co3 + h2s?

Hey there!:

The reactions will produce the respective sulfides as the precipitate. The balencing is done by counting the each individual atom on left hand side and right hande side. Since the valency of Ca is 2 and also S is 2, it will produce Cas, where as S is 2 and sodium is 1, it will form Na2S

a) Ca(OH)₂ (s)+ H₂S (g) > CaS (s) + 2 H₂O

b)  Na₂CO₃ (aq) + H₂S (g) > 2 NaS (s) + H₂O + CO₂

I hope this will help !!

the product of the pressure and volume is also constant

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
