In diamond, The arrangement of carbon atoms follows a tetrahedral shape. Each carbon is attached to four other carbon
atoms, forming strong covalent bonds.This arrangement of the diamond is very durable and rigidity, that's why is necessary so many energy to break it.
On the other hand, graphite, has a different geometric
arrangement. the carbon atoms are arranged in 2D sheets and each carbon is linked to three other carbon atoms, forming
hexagonal rings that are easily broken.
The pressure of the oxygen gas collected : 718 mmHg
<h3>Further explanation</h3>
Given
P tot = 748 mmHg
P water vapour = 30 mmHg
Required
P Oxygen
Solution
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
P tot = P H₂O + P Oxygen
P Oxygen = 748 mmHg - 30 mmHg
P Oxygen = 718 mmHg
Energy is released as a bond is formed
