Data Given:
Change in Entropy = ΔH = 120.5 kJ = 1.20 × 10⁵ J
Temperature = T = 298 K
Change in Entropy = ΔS = 758.2 J/K
Using Formula,
ΔG = ΔH - T ΔS
Putting Values,
ΔG = (1.20 × 10⁵ J) - (298 K × 758.2 J/K)
ΔG = -1.059 × 10⁵ J
ΔG = -105.94 kJ

Answer:
B. Extreme heat and pressure.....
Explanation:
This is how sedimentary rocks are actually made. I had learned recently in my class about these rocks, and my teacher told that these are made by heat and pressure. And these are the types of rocks that you'll find in canyons for example Grand Canyon.
You know that when something gets pressurized then it changes shape, same for rocks, if they're having lots of pressure on them, then they will also basically turn into newer rocks and also change shape. They also change looks because sedimentary rocks don't look like any other type of rock.
Also, heat can also be found in the crust of the earth since there is the Mantle under the crust which is filled up of MAGMA! (supa hot magma!! woohoo!) And also, because all of the dirt and stuff underground is packed together, the friction can also create heat. As you know, heat makes things expand, you might have done this before.... when you learned about hot and cold gas, you might have also learned that hot gases are more larger, and require more volume than cold gas. That means that the size of the object changes, that too, it's not just for gas, it's for everything, <em>including rocks!</em>.
Hence, your answer is B. Extreme heat and pressure from inside the earths surface......

Have a great day!
Water , H2O, is a molecule made of oxygen and hydrogen. The bonds that hold water molecules together are due to shared ELECTRONS, and known as covalent bonds
