Answer:
The P Wave travels through Earth's crust more quickly than the S wave travels
Explanation:
P and S waves are types of seismic waves that travel through Earth's crust.
Some basic data we can read from this graph are:
- it takes around 13 minutes for P wave to travel 10000 kilometers.
- it takes around 25 minutes for S wave to travel 10000 kilometers.
Based on this data, we can conclude that, since P wave takes less time then S wave to travel the same distance, that means that it moves through Earth's interior more quickly.
Answer:
I think that A or C is the correct answer
The reaction will be spontaneous if Gibb free energy is negative, according the following relation:
G = H - T*S
where G is Gibbs free energy, T is change of enthalpy , T is temperature and S is change of entropy
In the case of ammonia:
G = -93000 - 356*(-198) = -93000 + 70488 = -22512 j/mol
As G < 0 then the reaction is spontaneous.
