The answer would be c. Have you ever seen gravy? It always separates and leaves different layers.
Answer:
Explanation:
Assumptions
- They would ionize completely, or you must assume that.
- The volumes must be the same as well.
- 0.11M Cu(NO3)2 ===> 0.11MCu2+ + 0.22 NO3-
Note
The concentrations would merely add. All things change if the assumptions I've made are not true.
Don't bet any money on this but I think its [Pt(NH3)3] Cl2
The statement that is true about magnets is ''Similar poles of a magnet repel each other.''
<h3>What are the characteristics of magnet?</h3>

Answer:
1984
Explanation:
Given the formula;
0.693/t1/2 = 2.303/t log (Ao/A)
Where;
t1/2 = half life of the radioactive isotope
t= age of the wine
Ao= initial activity of the wine
A= activity of the at time = t
0.693/12.3 = 2.303/t log (5.5/0.688)
0.693/12.3 = 2.079/t
0.056 = 2.079/t
t= 2.079/0.056
t= 37 years
The wine was produced 37 years ago which means that it was produced in the year 1984
