Volume of oxygen gas evolved at S.T.P when `50ml` of `1.5M` `H_(2)O_(2)` ,is decomposed completely

Find the volume of oxygen gas liberated at STP. When 25ml of '30 volumes' H_(2)O _(2) is completely decomposed.

Total volume of gases evolved at STP when 36 g of H_(2)O are completely electrolysed between platinum electrodes

The volume of oxygen gas liberated at NTP from 30 mL of 20 (V H_2O_2) , solution is

The volume of oxygen liberated at STP from 15 mL of 20 volume H_2 O_2 is

The volume of oxygen liberated from 15 ml of 20 volume H_(2)O_(2) is

Volume of 0.1M KMnO_(4) solution required to oxidise 20ml of 0.5M of H_(2)O_(2) solution in presence of H_(2)SO_(4) is? (A) 80ml, (B)40ml (C)20ml (D) 10ml

Assertion If 10 mL of a H_(2)O_(2) solution required 8.00 mL of 0.02 M acidified KMnO_(4) solution for complete oxidation, 12.50 mL of same H_(2)O_(2) will oxidise completely to 5.00 mL of 0.10 M Na_(2)C_(2)O_(4) solution. Reason H_(2)O_(2) act as both oxidising as well as reducing agent.

What volume of oxygen gas (O_(2)) measured at 0^(@)C and 1 atm, is needed to burn completely 1L of propane gas (C_(3)H_(8)) measured under the same conditions ?
