C2H5OH(l)+3O2(g)→2CO2(g)+3H2O(g) If 9.2g of C2H5OH(l) burns completely in the presence of excess O2(g) according to the equation, how many grams of CO2(g) are produced?
A:0.40g
B:8.8g
C:9.2g
D:18g

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

The answer is accuracy
