Which lists mixtures, in order, from the smallest particles to the largest particles?
2 answers:
Answer: The correct answer is option (A).
Explanation:
In solution, size of the particles smaller than 1 nano meter which are not visible to the eyes.
In the suspension, size of particles are larger than the 1000 nano-meter which can be seen with the help of eyes.
In colloidal solution, size of the particles ranges from 1 nano-meter to 1 micrometer, which are not visible to eyes.
So, the order is :

Answer:
Average rate of reaction expressed in moles H₂ consumed per liter per second = 0.0025 M/s = 0.0025 mol/L.s
Explanation:
The complete, correct Question, is presented in the attached image to this answer.
The average rate of reaction in terms of the reactant is defined as the total amount of reactant consumed over a period of time divided by total period of time.
Mathematically,
Average rate of reaction = (change in concentration of H₂ over a period of time) ÷ (total period of time)
Average rate of reaction = (-ΔC)/(Δt)
The minus sign is there because the concentration of reactants reduce with time.
change in concentration of H₂ = -ΔC
= -(0.02 - 0.03) = 0.01 M
Time = Δt = 4 - 0 = 4.0 s
Average rate of reaction = (0.01/4) = 0.0025 M/s
We could solve for the average rate of reaction expressed in moles Cl₂ consumed per liter per second
change in concentration of Cl₂ = -ΔC
= -(0.04 - 0.05) = 0.01 M
Time = Δt = 4 - 0 = 4.0 s
Average rate of reaction = (0.01/4) = 0.0025 M/s = 0.0025 mol/L.s
Hope this Helps!!!
