Answer: 5.3 moles
Explanation:
Hi, to answer this question we have to apply the next formula:
n = PV/RT
Where:
n = number of moles
P= Pressure = 2.15 atm
V= volume = 60.5 L
R = 0.0821 atm(L)/mol(K)
T = temperature = 25 °+ 273.15 = 298.15 Kelvin
Replacing with the values given:
n = 2.15 (60.5) / 0.0821 (298.15) = 5.3 moles.
Feel free to ask for more if needed or if you did not understand something.
Answer:
Increasing temperature
Explanation:

Enthalpy of the reaction = -393.5 kJ/mol
Negative sign implies that reaction is exothermic.
Effect of change in reaction condition is explained by Le chateliers principle.
According to Le chateliers principle, if the reaction conditions of a reversible reaction in a state of dynamic equilibirum is changed, the reaction will move in a direction to counteract the change.
1. Increasing the temperature
Forward reaction is exothermic that means temperature increases in forward direction. Backward reaction will be endothermic and so there is decrease in temperature in backward direction or in left direction.
On increasing temperature, reaction will be move in direction to counteract the increased temperature, therefore reaction will move in left direction.
2. Adding O2
If O2 is added, then reaction will move in a direction in which its get consumed. So, reaction will move in forward direction or in right direction.
3. Removing C (s)
Le Chatelier's principle does not apply on solids, so removal of C(s) does not affect the equilibrium.
Answer:

Explanation:
The temperature and amount of gas are constant, so we can use Boyle’s Law.

Calculations:

1. The metamorphic rocks are produced when the parent or the pre-existing rocks (whether sedimentary, igneous, or even metamorphic) are changed by pressure, heat, and the chemical activity of the fluids.
When the prime changing factor is heat, generally due to direct contact, it may go through fundamental modification in recrystallization and texture is known as contact metamorphism. While regional metamorphism takes place when the minerals and texture of the rock are modified by pressure and heat.
