No. Since BH3 lacks a lone pair it would be a Lewis acid.


What does an empirical formula show?

the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)

What pair of element types are most likely to form a covalent compound?

Carbon (C) and Oxygen (O) together they can form: (CO) carbon monoxide (CO2) carbon dioxide (CO3) carbon trioxide For elements to bond covalently, they both need to be non-metals.


What is the molecular structure of ammonia?

Trigonal pyramidal (see wikipedia article "Trigonal pyramidal molecular geometry" for a picture. In terms of VSEPR it is an AX3E compound so the three N-H bonds and the lone pair are approximately tetrahedrel- but as the lone pair repels a little more the bond angle is less than 109.50 at 1080
