cations and anions
A solution is not permable; permeable is the material which allow the passage of the solution.
Semi permeable membrane means a very thin layer of material which allows some molecule to pass through them and prevent some molecule to pass through them. Osmosis is the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. So the membrane should be semi-permeable so as to only allow the movement of H2O molecules and not the other molecules of the mixture.
Diffusion is the net movement of particles(atoms,ions or molecules) from a region where are of higher concentration to a region where they are of lower concentration, down a concentration gradient.Factors that affect the rate of diffusion1.Temperature2.the concentration gradient3.Physical movement4 surface area to volume ratioThe passage of water from the less concentrated solution to the more concentrated solution across a partially permeable membrane is a process called osmosis
because,starch undergoes a photochemical reaction. So, with the passage of time it can under go to the photochemical reaction and starch wouldnot be starch but it might have changed in anyother product. so...we should use freshly prepared starch.
No.MgO has a giant ionic lattice structure with strong covalent bonds.for ionic compounds,they can only conduct electricity in aqueous or molten state because the giant ionic lattice structure had collapsed and ions are free to move about to conduct electricity.but in solid state,the ions will be held in fixed position and thus is unable to conduct electricity:)
A complete circuit provides the passage of electricity.
yes, passage of electricity depends on the structure of material at atomic level since electricity is nothing but flow of charge, any material which acquires charge(electrons or ions) on it, can allow passage of electricity. mercury being a metal, contains free electrons which is responsible for passage of electricity
A solution is not permable; permeable is the material which allow the passage of the solution.
It is an insulator.
Passage is where the horse preforms an elevated trot with minimal forward movement.
What does the passage decribe?
A material that does not conduct (or allow the 'passage' of) electricity is called an "insulator".
The Middle Passage
We define Osmosis as the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. It means that Semi permeable membrane is a very thin layer of material which allows some molecule to pass through them and prevent some molecule from pass through them. These molecules are decided by the type of solution. Generally, the membrane only allows movement of H2O molecules. So, if on one side is a saturated solution of something while on the other side is a dilute solution, the movement of molecules will be from both the directions but net result will be from saturated to dilute solution.
Osmosis.
electric circuit
Prevent the passage of electricity to or from (something) by covering it in nonconducting material.
