Answer:
92.0 torr/min.
Explanation:
- For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>
∵ The rate of the reaction = - 1/2(ΔP)NO/Δt = - (ΔP)Cl₂/Δt = 1/2(ΔP)NOCl/Δt.
∵ (ΔP)NO/Δt = - 184 torr/min.
<em>∴ The rate of change of the total pressure in the vessel = - 1/2(ΔP)NO/Δt</em> = (- 1/2)(- 184 torr/min) = <em>92.0 torr/min.</em>
Answer:
C2H4I2
Explanation:
Viscosity of a fluid has to do with the internal friction between the internal layers of the fluid.
Molecular weight is found to be related to the viscosity of a fluid even though the relationship may not be strictly linear.
However, the greater the molecular weight of a substance, the greater the viscosity of the material.
Since C2H4I2 has the greatest molecular weight (281.86 g/mol), it is also expected to display the greatest viscosity among all the compounds listed in the question.
Answer: The
is 
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pOH is calculated by taking negative logarithm of hydroxide ion concentration.
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
Putting in the values:
![pOH=-\log[6.4\times 10^{-5}]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5B6.4%5Ctimes%2010%5E%7B-5%7D%5D)



![9.81=-\log [H_3O^+]](https://tex.z-dn.net/?f=9.81%3D-%5Clog%20%5BH_3O%5E%2B%5D)
![[H_3O^+]=1.55\times 10^{-10}](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D1.55%5Ctimes%2010%5E%7B-10%7D)
Thus the
is
