Answer:
b. 17,190
Explanation:
Using the formula for C-14 dating,
where Present Value N =1/8 of Parent Sample
Initial Value, =1
Half Life, =5730 years
=17,190
Therefore the fossil is about 17190 years old.

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.
