    2Al + 3O2-->Al2O3 one mole requires 3/2=1.5 moles of O2 2Mg +O2-->MgO one mole required 1/2 moles of O2 P4+ 3O2-->P4O6 4Na + O2 --> 2Na2O one mole required 1/4 moles of O2 so D is the answer.

    python must be installed on the machine to run programs built on it. and virtual machine applications are slower than native applications. C++ for the win!!!

    actually the bond energy of both C≡C and O=O make this reaction energetically infeasible. C≡C will react with any other oxidising agent very easily because it is a very strong reducing agent.

    Na will also react with OH to make CH3CH(ONa)CO2Na so it is not correct.

    carbon monoxide will not react with oxygen to form CO2. carbon monoide does react with other compounds to form CO2 as it acts as a reducing agent but not with oxygen.

    don't make me mad, okay? Rules state that ANYONE can report a user who is violating the terms and the violator would be given a warining. on third warning his account will be closed. it was kind of me to tell him about rules than to report him.

    q20: propanol and sodium ethanoate will be formed. Mr(propanol):60 Mr(CH3CO2Na)=82 60/(82+60)=42.3% 24: actually one product can be made more than one mole. like 2 Y and one W. but combination of all of them can not make more than 8 carbons. maybe one molecule breaks up in 2Y+W and one breaks up...

    i was requesting you to remove it and also telling you about rules. i wasn't threatening you. if you won't remove it then go ahead do whatever but don't waste my time i have to solve doubts of other people.

    number of moles = 0.96/32=0.03 moles P=nRT/V=.03moles*8.31*(273+30)K / 7000x10^-6 m²=10.7KPa

    all C=C can show cis-trans it's more like permutation of mathematics. first C=C can be cis and trans, second can be either, third can be either there are two arrangements for first, two for second and two for third: 2*2*2=8
