Everying thing is mixture as everything have different compounds
My personal choice for a reference point would be the center of the Sun. That would most clearly reveal all of the motions involved.
Add barium chloride. Reaction equation as shown:
Li2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2LiCl(aq)
Reaction will result in a white precipitate, making the solution look milky.
Answer:
B. gas>liquid>solid
Explanation:
Entropy increases with increase in randomness,in gas randomness is higher than in liquid than in solid!

Answer:
Rock Y
Explanation:
The rock that is older shall be determined based on the number of half lives it has witnessed. A half life is simply the amount of time required for a sample to decay to half of its original mass.
Rock X
From 100% uranium, it decays to 50% uranium. This means it went through just one half life.
Rock Y
From 100% uranium to 25% uranium
100 --> 50 (first half life)
50 --> 25 (second half life)
This means it wen through 2 half lives.
Rock Y is older than Rock X
