Answer: He theorized that all material bodies are made up of indivisibly small “atoms.” Aristotle famously rejected atomism in On Generation and Corruption. Aristotle refused to believe that the whole of reality is reducible to a system of atoms.

Answer:
Explanation:
cent means “one hundredth”.
the meter is the base unit.
cent is a hundredth.
so there are 100 centimeters in a meter.
Answer:
Total pressure for both systems is 14.26atm.
Explanation:
Kp for the reaction is:
As C is a pure solid, <em>is not taken into account for Kp expression.</em>
5.207g of H₂ are:
5.207g ₓ (1 mol / 2.01g) = 2.59moles of gas.
Using PV = nRT:
P = 2.59molₓ0.082atmL/molKₓ1000K / 9.32L = 22.8atm
The expressions for pressure in equilibrium are:
P{H₂} = 22.8atm - 2X
P{CH₄} = X
Replacing in Kp expression:
0.263 = X / (22.8 - 2X)²
0.263 = X / 520 - 91.2X +4X²
136.8 - 24X + 1.052X² = X
<h3>136.8 - 25X + 1.052X² = 0</h3>
Solving for X:
<em>X = 8.54atm → Right solution</em>
X = 15.22atm → False solution. Because produce a negative concentration.
Replacing:
P{H₂} = 22.8atm - 2*8.54atm = 5.72atm
P{CH₄} = 8.54atm
Pressure of H₂ is 5.72atm and pressure of CH₄ is 8.54atm. Total pressure is:
5.72atm + 8.54atm = <em>14.26atm</em>
<em></em>
As mass of Carbon is not taken into account is Kp expression and mass of hydrogen is the same with the same volume, total pressure is also <em>14.26atm</em>
