Answer:
Igneous rock
Explanation:
The rock held by Florian is already a metamorphic rock. On further subjection for heat and pressure, the rock will melt to become igneous rocks.
- A banded rock is termed a gneiss
- In such a rock body, areas concentrating dark minerals and light minerals alternates to form the distinct domains.
- This in turn results from a very high grade metamorphic event.
- In retrospect, if this rock body is further heated, a melt or magma form which is the material by which igneous rocks are derived from.
I believe Calcareous is not a hydrogenous sediment. Hydrogenous sediments are example of marine sediments that are formed directly from chemical processes in sea water. They include, manganese nodules, phophorites, metal sulfides, evaporites and carrbonates. In shallower areas, such as on continental shelves and near islands, rock salt, calcium salts and sulfates may settle on the ocean floor.
I'm guessing it's a completing the answer question
<span>5.824x10^22 atoms of cobalt are in 5.699 grams of cobalt.
First, determine the number of moles of cobalt you have by dividing the mass of cobalt by the atomic weight of cobalt. So
Atomic weight cobalt = 58.933195
Mole cobalt = 5.699 g / 58.933195 g/mol = 0.096702716 mol
Now to determine the number of atoms, multiply by Avogadro's number. So
0.096702716 * 6.0221409x10^23 = 5.823574x10^22
Rounding to 4 significant figures, gives 5.824x10^22</span>
