rust is iron (III) oxide Fe2O3 the owner of a 1959 cadillac convertable wants to restore it by removing the rust with oxalic acid but he needs to know how many moles of rust will be involved in the reaction how many moles of iron (III) oxide are contained in 2.50 kg of rust?

Ithink it’s one of those things that you put the object on

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 correct answer is b) false
