Explanation:
Relation between pressure, latent heat of fusion, and change in volume is as follows.
Also, 
where, 
is the difference in specific volumes.
Hence, 
As, 
= 22.0 J/mol K
And, 
...... (1)
where, 
= density of water
= density of ice
M = molar mass of water = 
Therefore, using formula in equation (1) we will calculate the volume of fusion as follows.
= 
= 
Therefore, calculate the required pressure as follows.
= 
or, = 145 bar/K
Hence, for change of 1 degree pressure the decrease is 145 bar and for 4.7 degree change dP = 
= 681.5 bar
Thus, we can conclude that pressure should be increased by 681.5 bar to cause 4.7 degree change in melting point.

Answer:
Two thirds the number of moles of hydrogen
Explanation:
The balanced reaction is
3H₂ + N₂ → 2NH₃
So 1 mol of nitrogen gas reacts completely with 3 moles of hydrogen gas, to produce 2 moles of ammonia.
If equal moles of nitrogen and hydrogen are combined, <em>then hydrogen would be the limiting reactant</em>. Let's say we have 3 moles of each reactant, one mol of N₂ reacts with the 3 moles of H₂ and produces 2 moles of NH₃, and 2 moles of N₂ would remain. So the answer is<em> two thirds the number of moles of hydrogen.</em>
Answer:
C- the breakdown of rock into sediment
Explanation:
Because sedimentary rocks have layers and are made of of those layers which are made up of the breakdown of rock into sediment.
hope this helps:)
