0.308g of an organic Compound Carbon, Hydrogen and oxygen, on Combustion game
0438 0.4389 of Carbon and
0.269g of water if the vapour density of
the compound is 62
Calculate
(a) its empirical formula
(b) its molecular formua

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the answer would be b i believe

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
