Massa molecular C2H5OH : 2x12 + 6 +16 = 46 g/mol n = massa/massa molecular n = 32000g/46gmol = 762 mols --- calculando o calor de combustao C2H5OH + 3O² >>> 2CO² + 3H²O Hcombustao = Hreagentes- Hprodutos.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
