Answer: D. the hardening of liquid magma that leads to igneous rock
Explanation:
<h3>
Answer:</h3>
51.93 L
<h3>
Explanation:</h3>
From the question we are given the following components of an ideal gas;
Number of moles = 21.5 mol
Pressure, P = 9.65 atm
Temperature, T = 10.90°C, but K= °C + 273.15
=284.05 k
We are required to calculate the volume of the ideal gas.
We are going to use the ideal gas equation which is given by;
PV = nRT, where P, V, T and n are the pressure, volume, temperature and moles of the ideal gas respectively. R is the ideal gas constant, 0.082057 L.atm/mol.K
To get the volume, we rearrange the formula to get;
V = nRT ÷ P
= (21.5 × 0.082057 × 284.05 K) ÷ 9.65 atm
= 51.93 L
Thus, the volume of the ideal gas is 51.93 L

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.
