Ba(NO3)2 and Al(OH)3
A compound is defined as a substance that contains at least two chemical elements and always has a constant mass ratio between elements for each possible pair of the elements that are present in it.
3 bonding pairs and one lone pair or non-bonding pair
No. Since BH3 lacks a lone pair it would be a Lewis acid.
The imaginary compound nitrogen pentaiodide would be NI5 , it would not be an acid- there are no ionisable H atoms. (or a Lewis acid- it has no lone pair.) There is a real compound NI3, a very unstable substance a contact explosive. There is a reported PI5, but that is disputed.
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
Ba(NO3)2 and Al(OH)3
Examples of radicals in chemistry are: OH., :CH2, Cl., ClO. etc.
CH3COH(CH3)2; (Ch3) 3COH

no
The Lewis Theory describes a base as a compound that donates an electron pair. By donating the electron pair there is a covalent bond.
Factorise 12.Replace each pair appearing in this factorisation as by the same number outside the radical and then put everything under the radical sign. sqrt(12) = sqrt(2*2*3) = 2*sqrt(3)

Joining accepted principles of right and wrong as a pair, joined together, especially in a pair or pairs; coupled. Inversely or oppositely, related with respect to one of a group of otherwise identical properties. "radical ethical"
The word is "peacetime" - the EA pair has a long E sound, the same as made by EE in wheel.
compound ineqality
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!)
