We let x be the pressure of each product at equilibrium, giving this ICE table:
2NO2 (g) ↔ 2NO (g) + O2 (g)
Initial pressure (atm): 0.500 0 0
Change (atm): -2x +2x +x
Equilibrium (atm): 0.500-2x 2x x
We can calculate x from Kp:
Kp = [NO]^2 [O2] / [NO2]^26.5x10^-6 = (2x)^2 (x) / (0.500-2x)^2
Approximating that 2x is negligible compared to 0.500 simplifies the equation to
6.5x10^-6 = (2x)^2 (x)/(0.500)^2 = 4x^3 / (0.500)^2
Then we solve for x:
x3 = (6.5x10^-6)(0.500)^2 / 4
x = 0.00741
The pressure of NO2 at equilibrium is therefore
Pressure of NO2 = 0.500-2x = 0.500 - 2(0.00741) = 0.4852 atm
Answer:
The answer is that ethane gas has a density of 1.34 g/L at STP
Explanation:
Ethane weighs 0.0013562 gram per cubic centimeter or 1.3562 kilogram per cubic meter, i.e. density of ethane is equal to 1.3562 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure.
Answer:
It is known generally that polar compounds are soluble in polar solvents. Based on the structure of benzoic acid, it comprises the non-polar C6H6 group and polar COOH group. Based on the structure, in benzoic acid, the nonpolar hydrocarbon outweighs and influences the polar part as nonpolar, due to which benzoic acid is not soluble in water.
On the other hand, benzoic acid produces sodium salt benzoic acid when it reacts with 2.5 M sodium hydroxide, this salt is ionic. Generally, the ionic compounds are soluble in water. Therefore, the salt of benzoic acid gets dissolved in water. Hence, benzoic acid is soluble in the solution of sodium hydroxide.
The object that is less dense will float on top of the object that is more dense.
