Analytical
Analytical chemistry seeks to determine the composition of substances.
Explanation:
Let us assume that mass of nickel(II) iodide is 2.90 g, volume is 150.ml, and concentration is 0.70 M.
When is added into the solution then it will not affect the concentration.
Moles of =
=
= 0.00928 mol
Moles of =
=
= 0.01856 mol
Molarity of =
=
= 0.124 M
Thus, we can conclude that final molarity of iodide anion in the solution is 0.124 M.

Entropy is the degree of disorderliness in a system. Among the phases, solid
has the most ordered structure. Therefore, the lowest entropy. The least ordered is the gas phase which represents the highest entropy. Therefore, the correct answer is option D, steam. </span>
Answer: B) Bones
Explanation:
Natural casts form when flowing water removes all of the original bone or tissue, leaving just an impression in sediment.
