What is the total volume of gas produced from the decomposition of #100cm^3# of #0.2 mol#/#dm^3# hydrogen peroxide(#H_2 O_2#)?
The balanced equation for the decomposition of #H_2 O_2# is: #H_2 O_2 -> 2H_2 O + O_2#
The balanced equation for the decomposition of
1 Answer
Approx.
Explanation:
You have got the stoichiometric equation...
And this tells me UNEQUIVOCALLY that one mole of dioxygen gas results from the (usually Mn salt-catalyzed) decomposition of TWO mole of hydrogen peroxide. This is clearly a disproportionation reaction, in that peroxo
And thus given complete reaction,
Under standard laboratory conditions, the molar volume of an ideal gas is
And so we take the product....
