153g/mols I think this is the answer but not 100% sure.
According to the cooling curve given above, at temperature 275K, the phases that will be observed is LIQUID AND SOLID.
The flat points on the graph represent the points where phase changes are taking place.The beginning of the first flat point represent the point where the gas become liquid, the extreme end of this point indicate the point where the liquid has started turning to liquid and that is the point of 275K. Thus at that point both phases are present.
Sorry I’m only answering so I could upload
Answer:
All the above
Explanation:
A. Electrical current conduction
Aqueous solutions of both strong and weak acids will conduct an electric current. Weak acids are poorer conductors because they produce fewer ions.
B. Reaction with magnesium
Both strong and weak acids will react with magnesium, although weak acids will react more slowly.
C. pH paper test
Both strong and weak acids will give a colour with pH test paper, although the colours will probably be different.
D. Litmus paper test
Both strong and weak acids will turn blue litmus red.
