Popular questions
Is nitrosyl chloride polar?
Yes—NOCl is a polar molecule due to its bent geometry at nitrogen and the differing electronegativities of O and Cl, which produce a net dipole.
(b) in which species (no2cl or no3-) are the n-o bond(s) longer? nitrosyl chloride nitrate ion?
Longer in nitrate (NO3−): its N–O bonds have lower bond order (~1.33) than the N=O double bond in nitrosyl chloride, so they are longer.
How is nitrosyl chloride used?
As the additive E919 it was historically used as a flour treatment/bleaching agent, but this use is now largely discontinued and not authorized in the EU; today it is mainly an industrial chlorinating/nitrosating reagent rather than a common food additive.
Nitrosyl chloride nocl decomposes to nitric oxide and chlorine when heated answer l?
Yes—on heating, 2 NOCl → 2 NO + Cl2, and the decomposition is promoted by heat and light.
Question 6 what is the "axe" description of the nitrosyl chloride molecule?
AX2E1 at the nitrogen center (two bonded atoms and one lone pair), giving trigonal planar electron geometry and a bent molecular shape.
What does amylase break down?
It breaks down starch (amylose and amylopectin) by cleaving alpha-1,4-glycosidic bonds into shorter sugars such as maltose, maltotriose, and dextrins.
What does amylase do?
Alpha-amylase catalyzes the hydrolysis of starch into shorter, fermentable sugars; in foods it reduces starch viscosity and helps baking and brewing by generating sugars for yeast.
Where is amylase produced?
In humans it’s produced by the salivary glands and the pancreas; industrially (E1100) it’s made mainly by microbial fermentation (e.g., Bacillus or Aspergillus), and plants also produce it.
Where is amylase found?
It occurs in saliva and pancreatic secretions, in many plants and microorganisms, and in foods as a processing aid in baked goods, brewing, and starch syrups.
Is amylase an enzyme?
Yes—alpha-amylase (E1100) is an enzyme (a glycoside hydrolase) that breaks down starch.
