Combined Chemistry is killing me...everything sounds alien to
me.Mole concept is one part i dont understand and helping me would
be excellent.
I need to know how to do calculation on the mole.
I.e. Ethene C2H4 burn o2 to form co2 and h20.
Write equation:
C2H4 + 2o2 = 2co2 + 2h20(my ans)
2)cal the mass of co2 and mass of h20 formed when 0.28g of ethene
are complete burned in o2.
For this question i know that u have to compare the number of mole
for the first mass and the last one(c2h4 and co2 - compare like
division style)
However after that(finding the no of mole), how u proceed?The
questions ends with either "0.28g","25cm3" or "1g" so i do not have
a direct one-way-for-all method.And they start with find volume or
find mass so the questions are all diff.
