Answer: Filtration
Explanation:
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. There is a physical boundary between the dispersed phase and dispersion medium.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different. There is no physical boundary between the dispersed phase and dispersion medium.
Filtration is a type of mechanical separation process in which the smaller particles are separated from the bigger particles through the filter paper where small particles pass through the fine holes of filter paper and the left ones remain on the filter paper.
So the question ask to calculate the Ks of the monoprotic acid where as it is dissolved in water to produce 0.0136 M solutions and the PH result of the solutions is 2.45. So the Ka of the problem is 1.25 x 10^-3. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications about the problem
Answer:
Explanation:
Number of molecules = Moles x Avogadro number
= 65 x 6.022 x 10^23
= 3.9 x 10^25
