yes that makes sense i made a silly error , thank you!

ohh wait yeah ur right, its H2 gas

I can add more explanation to this question .This is also a redox reaction in which K is losing electron and one H is gaining it. So one H is becoming H^- from water and other stays as H ⁺ which gives the product as H₂ gas.

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

I did a seperate page,  but here is the question

its not letting me upload the question

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. 

I'm still confused, slightly

As we move down the group size increases and acidity also increases because it is easy to break the bond of H .Big bonds are weak bonds.Hence H₂Po is stronger than H₂Te.
However we know that Po is a rare and radioactive element.

because as you go down the group size increases? So that would mean Po would be the biggest in size and be the weakest Bronsted acid?
