In the following equation, a 2.00 g sample of methane is mixed with 4.00 g of oxygen. What is the limiting reactant? How many grams of H2O are produced? CH4 + 2O2 à 2H2O + CO2

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
