ting together of the colloidal particle so as to change them into LARGE SIZED particles which then SETTLES down as a PRECIPITATE is KNOWN as coagulation.

hy dude ur answer is Explanation:Adding or removing energy from MATTER causes a PHYSICAL change as matter MOVES from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become STEAM or vapor (a gas

As TEMPERATURE decreases density increases so the MATTER will contract.

---------> sorption:-When both the adsorption and absorption occur simultaneously and are not distinguishable, such a PROCESS is called sorption.---------> positive and negative:-Negative and positive are opposites in other senses. Mathematically, there are positive (+) NUMBERS, and negative (-) numbers. I can have a positive (good) attitude, or a negative (bad) attitude. Just as "good" is the opposite of "bad" and of "EVIL," "negative"s meaning depends on what you contrast it with.--------> physisorption and chemisorption:-PhysisorptionPhysisorption is also known as physical adsorption and it is an exothermic process. Its adsorption ENTHALPY is low, nearly 20 to 40 kJ/mol. Normally in physisorption, the gas is accumulated on the solid surface due to weak force, known as Van der Waals forces.chemisorption Chemisorption is also known as chemical adsorption. In chemisorption, adsorption takes place in adsorbed substance that is held by chemical bonds. Chemisorption has high specificity that is it is highly specific, and it takes place only if there is a chemical bonding between adsorbent and adsorbate.adsorption isotherm Adsorption Isotherm is a curve that expresses the variation in the amount of gas adsorbed by the adsorbent with pressure at constant temperature.

Yes it is true.Let me clear one thing,true SOLUTIONS are also called homogenous mixturesExplanation:In true solutions,the SOLUTE and.the SOLVENT gets mixed so uniformly that breaks the solute molecules/particles into finer and finer particles.As there is no obstacle in between,the light passes in a straight LINE without REBOUNDING in any direction.E.g-sugar and salt solution.

The elimination of unwanted water, or ultrafiltration, OCCURS through osmosis. The dialysis solution has a high CONCENTRATION of glucose, and this causes osmotic pressure. The pressure causes the fluid to MOVE from the blood into the DIALYSATE. As a result, more fluid is drained than is introduced.Explanation:

tion:A sol is a colloidal suspension of very small solid particles in a CONTINUOUS LIQUID medium. Due to strong Particle-solvent INTERACTIONS interactions, the colloidal particles get STRONGLY SOLVATED in dispersion medium and is the main reason for the stability of colloidal sols.

Explanation:The value of colligative properties of colloidal solution are of small order in comparison to those of TRUE solution of same concentration because of colloidal particles are comparatively less in number. This is due to slight large size of colloidal particles in comparison to particles PRESENT in true solution.HOPE IT HELPS YOU...PLEASE MARK BRAINLIEST...

it seems to be first recognised as GREEN and SLOWLY TURNS to fine SOL

In  ultrafiltration  (the process of separating the colloidal particles from the solvent and soluble solutes) colloidal particles can pass through ordinary filter paper because the pores are too large.  These pores of filter paper can be reduced in size by impregnating with colloidion SOLUTION to stop the flow of colloidal particles.  The usual colloidion is a 4% solution of nitro- cellulose in a mixture of alcohol and ether.  An ultra-filter paper MAY be prepared by soaking the filter paper in a colloidion solution, hardening by FORMALDEHYDE and then finally drying it.  Thus, by using ultra-filter paper, the colloidal particles are separated from REST of the materials.

Electrical Disintegration/ BREDIG's arc Method: This is applied to obtain colloidal sols of METALS LIKE gold, silver and platinum. An electric arc is STUCK between the electrodes of the METAL immersed in the dispersion medium.

I think you mean copper(I) OXIDE, Cu₂O, and that you are asking for the percentage by mass of copper in this COMPOUND. WELL, look up the atomic weights of copper and oxygen; add them appropriately; divide the total for the copper by the total for the molecule; then multiply by 100 to GET it as a percentage.

ctants diffuse to the surface of the catalysts. In this PROCESS, the reactants first get in CONTACT with the external surface, out of which some of them cross the BARRIER and enter the interior exposed surface that includes paths and cracks on the external surface.please mark me as brainlist answer please please please REQUESTING

Because of sedimentation deposits from the PASSING and DIFFERING currents that collide at the 'border' of the two WATERS and in a way drop their BAGS (the sedimentation). Explanation:

e some general characteristics of solid catalysts:-1. A catalyst can change their physical state but it will always remain UNCHANGED in chemical composition & mass.2. In Order to catalyse a reaction there will be need of a very small AMOUNT catalyst.3. It never initiates any reaction it just supports reaction.4. In CASE the catalyst is solid then it will work more efficiently if it is finely divided.5. There will be no affect on the nature of the PRODUCT even if reaction is DONE by the help of a catalyst.

platinumExplanation:During ostwald process ammonia is CONVERTED to nitric acid in 2 STAGES. It is oxidized by heating with OXYGEN in the presence of a catalyst such as platinum with 10% rhodium, platinum metal on fused silica wool, copper or nickel, to form nitric OXIDE (nitrogen(II) oxide) and water/steam
