The moment magnitude scale is a scale that rates earthquakes by estimating the total energy released by an earthquake . Estimating the total amount of energy released, enables comparison of earthquakes more accurately.
This scale can be used to rate earthquakes of all sizes, near or far. The following statements describe the moment magnitude scale:
B. It collects data using a seismograph.
D. It estimates the total energy released from an earthquake.
E. It determines the amount of damage caused by an earthquake.
Answer:
See explanation
Explanation:
The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.
Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.
However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.
I would say B.HS(aq)+NiSO4(aq)
Answer:
-484kJ
Explanation:
Carry out bond energy calculation
[6(C-H) + (C=O) +2(C-C)] - [(O-H) +7(C-H)+ (C-O) +2(C-C)]
Substitute the bond energy values = -484kJ
Because while doing research scientist follow the scientific metod.The scientific method involves exploration and observation and the search for the answer for a question. And there will always some hypotesis that while experimenting reveal to be wrong.
