Ba(NO3)2 and Al(OH)3
The Lewis structure of PF3 shows that the central phosphorus atom has one non-bonding electron pair and three bonding electron pairs. Phosphorus has five valence electrons, and in PF3, one is non-bonding while the other three are shared in bonds with the fluorine atoms.
The question is incomplete. No options are given (for which of the following) to answer the question.
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.
No. Since BH3 lacks a lone pair it would be a Lewis acid.
Fluorine and iodine are not a likely pair to form an ionic compound because they are both nonmetals with similar electronegativities. Ionic compounds typically form between a metal and a nonmetal where the metal loses electrons and the nonmetal gains electrons to achieve stability.
Ba(NO3)2 and Al(OH)3
A compound radical is a group of atoms that remains intact during a chemical reaction and behaves as a single entity, usually carrying a charge. Examples include sulfate (SO4^2-) and ammonium (NH4+). They are commonly found in organic compounds and coordination complexes.

The pair of formulas that represents the same compound is H2O and H-O-H. Both formulas represent a water molecule, where one oxygen atom is connected to two hydrogen atoms.
no
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.
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!)

A pair of inequalities joined by "and" is called a conjunction, while a pair of inequalities joined by "or" is called a disjunction.
