What is a biopolymer? Kenneth Davies A polymer is a high molecular weight molecule that is made up of repeating molecular units monomers.
Some polymers are synthetic nylon, polystyrene, etc. The polymers deriver from natural systems are called biopolymers. Can you please inform me on the theory of Emulsions?
Eliza Ritchie Emulsions are colloidal dispersions of two immiscible liquids, or liquids that are not soluble in each other.
So, as an example, vinegar is mostly water. When shaken with a salad oil, as in the preparation of a salad dressing, a temporary oil-in-vinegar emulsion is formed. This quickly separates into a layer of oil and a layer of vinegar. On the other hand, mayonnaise is also an oil-in-vinegar emulsion in which the egg yolks, a colloidal material, act as an emulsifying agent that stabilises the dispersed oil droplets with a protective film that prevents their coalescence.
Another good example is that of soap which is a classic emulsifying agent in that it can emulsify oily dirt so that it can be rinsed away. Can you please give me some examples of esters, their occurance, production and uses?
It is prepared mostly by esterification of salicylic acid with methanol and is present naturally in the leaves of Gaultheria procumbens and in the bark of Betula lenta.
Methyl Salicylate is used in perfumery and for flavouring sweets, as well as a therapeutic use as a counter-irritant. Its uses are varied, and include a pharmaceutical aid flavour ; artificial fruit essences; solvent for nitrocellulose, varnishes, lacquers and aeroplane dopes; cleaning textiles, and more!
Ethyl Acrylate is used as a monomer in the manufacture of water emulsion paint vehicles, in the production of emulsion-based polymers used in textile and paper coatings, leather finish resins and adhesives, and imparts flexibility to hard films. Are there any coloured surfactants?
Ekta Mahajan The simple answer to this is NO! What is a household product that is a made of polar molecules, b a hydrocarbon with a molecular weight of or more, and c made of Sodium Carbonate?
Brittni Vorrhis b Moisturising creams, olive oil c Alkaseltzer ant-acid tabletssome washing powders With the condensation polymers, why are they called 'condensation'? Does that indicate the production of water specifically?
Also known as polycondensation. Polymerisationin which monomers are linked together with the splitting off elimination of water or other simple molecules to give a condensation polymer.
Label with Formula and bonding type. J Stewart Our chemists were not sure of the context of your question, so the only answer they can give you is that CARBON does not dissolve in water, nor conducts electricity, and melts at C. After a reaction, I have to distill ethyl acrylate.
How do I clean everything and eliminate the odor?Convert to a Fraction Convert the ratio to a fraction by making the left side of the ratio the numerator and the right side the denominator. Reduce the expression by cancelling the common factors. Therefore, to convert this into a fraction, this will become 3 4/ Since 4/10 can still be simplified and both 4 and 10 are divisible by 2, this becomes 2/5, making this fraction 3 /5(13).

At the very name of another country, my heart would go out to it, and at the sight of a foreigner in the streets, I would fall to weaving a network of dreams,—the mountains, the glens, and the forests of his distant home, with his cottage in its setting, and the free and independent life of far-away wilds.
Evaluate expressions. A variable is a letter, for example x, y or z, that represents an unspecified number. $$6+x=12$$ To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations.
In the example above, the variable x . When two things vary inversely, the one goes down by the same fraction that the other goes up, and vice versa. In this case, y went from 10 to 8, that's a decrease of 8/10 or 4/5.
That means x went up (not down), it went up by 5/4, the inverse of 4/5.
