The partial pressure of nitrogen gas is calculated to be 21.16 MPa.
The partial pressure of oxygen equates to 5.62 MPa, and the overall gas pressure is stated as 26.78 MPa.
This adheres to the principle that the total pressure in a gas system equals the sum of all individual gas partial pressures.
Thus, the total pressure in the system reflects the sum of the partial pressures of nitrogen and oxygen.
Accordingly, the partial pressure for nitrogen can be derived as follows: Total pressure minus the partial pressure of oxygen.
Thus resulting in: 26.78 - 5.62, which gives a partial pressure of nitrogen at 21.16 MPa.
In the case of a 100m Race, displacement equals the distance traveled. If we divide this equation by the time t (assuming t represents the time taken to finish the 100m race), we derive that velocity equals speed. Conversely, in a 400m race where a full lap is completed, the racer’s starting and ending positions overlap, leading to displacement equaling 0, while the distance is not zero (400m). Therefore, it follows that displacement does not equal distance, leading to the conclusion that velocity does not equal speed.
1) To find the molar mass of C6H8O6, you must refer to the atomic weights of C, H, and O from the periodic table: C is 12; H is 1; O is 16 <span> (12x6)+(1x8)+(16x6)= 176g/mol
</span> <span> 176 g = 1 mol
0.5 g = x mol = 500 mg = 0.5 grams
Molar mass = mass ÷ moles
176 = 0.5 ÷ x
x = 2.84 x 10⁻³ mol
2) To calculate the total number of molecules in those </span> 2.84 x 10⁻³ mol, multiply the moles by <span> Avogadro's constant.
Number of molecules = Avogadro's constant x number of moles
Number of molecules = 6.022 x 10²³ x 2.84 x 10⁻³ </span> = 1.71 x 10²¹ molecules of vitamin C. <span>

Boyle's law describes the relationship between gas pressure and volume.
It asserts that at a constant temperature, pressure is inversely proportional to gas volume.
PV = k
where P represents pressure, V denotes volume, and k is a constant.
P1V1 = P2V2
where the parameters for the initial condition are on the left, and the parameters for the second condition appear on the right side of the formula.
By substituting values into the equation: 4.00 atm x 500 L = 8.0 atm x V
V calculates to 250 L.
Thus, the new volume becomes 250 L.
Let's represent molecules with symbols as follows:
C₂O₄ = X
and
H₂O = Y
Then,
K [ Co (X)₂ (Y)₂ ]
Since Potassium (K) has an oxidation number of +1
To achieve neutrality, the oxidation number of the coordination sphere needs to equal -1.
Thus,
[ Co (X)₂ (Y)₂ ] = -1
Given that,
the O.N of X is -2
Therefore,
O.N of (X)₂ equals -4
Additionally,
O.N of H₂O is zero since it remains neutral. Therefore,
[Co - 4 + 0 ] = -1
Or,
Co = -1 + 4
Co = +3
Conclusion:
The oxidation number for the coordination sphere is -1, and the oxidation state of copper is +3.
