Immiscible liquids are those which won't mix to give a single phase.
True
False
Oil and water are miscible.
True
False
The main 2 types of mass transport processes are:
Molecular diffusion and advection
Advection and convection
Molecular diffusion and radiation
Molecular diffusion occurs between 2 immiscible fluids.
True
False
Mass transport by diffusion is related to the ------------ between 2 miscible fluids.
(a)
Advection is the mass transport process related to the water ------.
(a)
This figure represents mass transport processes by advection-diffusion
True
False
This figure represents the mass transport of a contaminant in an aquifer.
We can confirm that the contaminant and freshwater are not miscible.
We can confirm that advection and diffusion processes occur
We can confirm that there is pure diffusion in this case
Based on the figure, select if the contaminant is saltwater or oil.
Saltwater
Oil
In this figure we can see:
The processes of mass transport by pure molecular diffusion
The processes of mass transport by pure advection
The process of mass transport by both advection and molecular diffusion
Aqueous reactions occur between species dissolved in water and generate speices dissolved in water.
True
False
Precipitation reactions occur between species dissolved in water and generate solid species.
True
False
Select all chemical reaction that may affect the porosity and the permeability of the porous media (multiple correct answers).
Aqueous reactions
Precipitation reaction
Dissolution reaction
Precipitation reactions increase the porosity of the porous media.
True
False
Dissolution reactions increases the porosity and permeability of the porous media
True
False
Select the good definition of biodegradation
A reaction that occurs between 2 species dissolved in water and Generate a solid species
is when species dissolved in water reacts with the solid grains and generate a new chemical species that can be dissolved in water
The reaction between organic contaminants in groundwater and indigenous microorganisms or bacteria.
The reaction related to the different electrical charges between the solid grains and the chemical species is:
A sorption reaction
precipitation reaction
Aqueous reaction
Dissolution reaction
