    Climate change caused by human activities that produce greenhouse gases with greenhouse effect are stipulated by the Kyoto Protocol.Greenhouse gases covered by the Protocol are: SO2, nitrogen oxides, CO, CO2,CH4, HFC, PFC and SF6.After passing a gaseous mixture of inorganic gases with density relative to hydrogen DH2 = 25, in an acidified solution of KMnO4, its volume is reduced by half and and the density of the mixture in relation to hydrogen isDH2 = 18. If the initial gas mixture is passed through an alkaline solution ofKMnO4 (HO-) it’s volume decreases for 4 times, and the density is reduced to DH2 = 14.

    Determine qualitative and quantitative composition in mole percent of the gaseous mixture knowing that its products of combustion with oxygen are completely absorbed by an alkaline solution.

    Solution > I started to see which gases reacts with abase after combustion:
    2SO2+ O2 = 2SO3 => SO3 + NaOH = NaHSO4
    2CO+ O2 = 2CO2 => CO2 + NaOH = NaHCO3 ............. and the same reaction for CO2

    So gases are CO, CO2 and SO2. And forwards I don’t know manage .. if anyone has any ideas to help me I will thank! The answer is: 50% SO2 , 25%CO si 20% CO2
