Answer:
500N/m²
Explanation:
The Pressure can be calculated using the formula:
P = F/A
Where;
F = force (N)
A = Area (m²)
Based on the information provided in the question, F = 30N, A = 0.06m²
P = F/A
P = 30/0.06
P = 500N/m²
Energy is released by the formation of chemical bonds, and energy is
absorbed when the bonds are broken.
<h3>What is a chemical reaction?</h3>
A chemical reaction involves the formation of new compounds from
reactants . It involves the formation and breaking of bonds in the
elements.
Energy is released by the formation of chemical bonds and this type of
reaction is referred to as exothermic while energy is absorbed when the
bonds are broken and is referred to as an endothermic reaction.

Answer:
Total partial pressure, Pt = 821 mm Hg
Partial pressure of Helium, P1 = 105 mm Hg
Partial pressure of Nitrogen, P2 = 312 mm Hg
Partial pressure of Oxygen, P3 = ? mm Hg
According to Dalton's law of Partial pressures,
Pt = P1 + P2 + P3
So, <u>P3 = 404 mm Hg</u>
