if
c+o2- co2
then why the residue, (which is also carbon) is not burnt properly.
whereas in the case of diamond it is burnt completely
1here iam asking that
residue after burnig wood that is ash does not burns whereas it is also carbon.
we can see in the case of diamond, it is carbon and burns completely by giving co2.
why????residue or ash being carbon do not under go combustion
i think i have made myself clear
please answer soon...........please
39Ash content of coal is the non-combustible residue left after coal is burnt. It represents the bulk mineral matter after carbon, oxygen, sulfur and water (including from clays) has been driven off during combustion. Analysis is fairly straightforward, with the coal thoroughly burnt and the ash material expressed as a percentage of the original weight.
its just non combustible
1i am very greatful to you yaar
actually my chemistry teacher had told me this
