La combustion de m1=64,85 g de methane (C²H⁶) dans une masse m2 de dioxygene (O2) conduit à la formation de m3= 76,85 g de dioxyde de carbone (CO2) et m4 = 3g de l'eau (H2o) 1/-Calculer la masse du dioxygéne.

Ethene molecular fórmula= c2h4molecular weight = 29.046g/molhope it : )

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.

Provide the choices you are given. i would be happy to : ) you!
