What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
Why graphite being a covelant compound conducts elecricity?
because it has charges particles between the different layers. These charges particles allow it to conduct electricity.
What are the functions of the cell membrane in a plant cell?
to allow non harmful particles through and keep harmful ones out
What the different from Porous Alumimium to aluminum?
Porous means that there are gaps in the particles that allow water through. Porous aluminum is not watertight.
What does heat allow melting to occur?
Because melting occur at high temperature; at this temperature bonds between particles are weaker.
Sodium Is discovered by?
Sir Humphry discovered in 1807 by using eletrolysis of caustic soda.
What type of particles must be able to pass through the barrier to allow electrolysis to take place to?
Positively charged particles
What do the constant motions of gas particles allow the gas to do?
The constant motions allow the gas to fill whatever contains it.
What are small particles that don't allow water to absorb quickly?
Chloroplast
Why is barium the most difficult group 2 metal to extract by eletrolysis?
I would guess it is because it is the most reactive so it is the hardest to reduce.
What type of particles of soil allow the least porosity?
Sand, Clay and Pebbles.
What are the properties that allow clay particles to slip and slide?
i am not sure but.....it might be your mom
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What material made of particles that can easily change location?
Metals are materials in which particles (electrons) can freely move. If you mean bigger particles (such as atoms or molecules), then liquids and gasses allow easy movement
Why only liquids are used as solvents but not solids?
In solids, the particles are joined too strongly and are positioned to closely together to allow other particles to mix with it
Why graphite being a covelant compound conducts elecricity?
because it has charges particles between the different layers. These charges particles allow it to conduct electricity.
What is a warm hole?
it is small particles present in the universe which allow us to enter in the future.
