hydrogen
greater the Mr more the boiling and metltin point
you did not remove the electrons in your rquation...thats it..the then balance it and tada its solved!helpp!! QA4 (b)(ii) from O/N 2011 paper 21 of chemistry.
the question is:
During a stage in photosynthesis, electrons are removed from water to produe hydrogen ions and oxygen gas.
Write an equation for this reaction.
i wrote:
2H2O --> 4H+(aq) + O2(g)
but in the marking scheme it is given:
2H2O --> 2H+ + O2 + 2e-
Explain please!!
the higher the mr the more dense it is...
the more dense the higher the volatality!!
removing the products or the reactant, favours the reversible direction in that way, similarly, adding any of the product or the reactant favours the reaction in the other direction!
a process in which D.C current is passed through a circuit to drive a chemical reaction!!

which electrons shud i remove. sorry i am beat ryt now... all i can think of is this formula and that reaction. its all mixed up!!
pressure and volume are almost the same!!!
no, all conditions are considered. this is probably the smallest and the dumbest and yet the worst topic of the chemistry syllabus to be frank
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
