For the reaction 2H2O(g)↽−−⇀2H2(g)+O2(g) 2 H 2 O ( g ) ↽ − − ⇀ 2 H 2 ( g ) + O 2 ( g ) the equilibrium concentrations were found to be [H2O]=0.250 M, [ H 2 O ] = 0.250 M, [H2]=0.360 M, [ H 2 ] = 0.360 M, and [O2]=0.750 M. [ O 2 ] = 0.750 M. What is the equilibrium constant for this reaction?

Kc = 1.55

Explanation:

This is the reaction:

       2H₂O (g)  ⇄    2H₂(g)    +     O₂(g)

Eq.   0.250M        0.360M          0.750M

The expression for Kc is.

Kc = [O₂] . [H₂]² / [H₂O]²

Kc = 0.750 . 0360² / 0.250²

Kc = 1.55

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

i believe the answer is true.
