Answer:
(a)
: reverse reaction is favored.
(b)
: reverse reaction is favored.
(c)
: reverse reaction is favored.
(d)
: forward reaction is favored.
Explanation:
Hello,
(a)
:
In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (acetic acid) will tend to have a higher concentration.
(b)
:
In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (silver chloride) will tend to have a higher concentration.
(c) 
In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (aluminium hydroxide) will tend to have a higher concentration.
(d) 
In this case, since the Ka is greater than 1, we infer the forward reaction is favored since the product (C) will tend to have a higher concentration.
Regards.

A molecule is formed when two or more atoms joined together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules. Hope I helped
Answer:

group 16 period 2 of the periodic table
note: that is not the electronic configuration, that is the Bohr model.
