I'm very confused about this question, first, why did the answer have H2 on the product side? I thought H+ ions were forming on the product side, not H2 gas? It also says 'aqueous,' which means it's in water. So, wouldn't the balanced chemical equation be, K (s) + H20 (L) ----> KOH (aq) + H+ (L)? I'm confused about how they obtained the gaseous H2.
its not letting me upload the question
Hi Sorry for late reply
Aditi H is atom and do not exist as it is very reactive. H is always H2 in reactions like O is O2 ,Cl is Cl2 .K is very reactive and displaces H from water as H2 gas. You need to balance the equation also.
2K(s) + H2O (l) ---> K2O + H2
yes that makes sense i made a silly error , thank you!
