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.
How does benzole peroxide reduce acne?
As a topical drug, benzoyl peroxide reduces acne by releasing oxygen that kills acne-causing bacteria and helps keep pores from clogging; as a food additive (E928) it’s used to bleach flour, not to treat acne.
How does benzole peroxide work?
In foods, benzoyl peroxide (E928) is a strong oxidizing flour-bleaching/maturing agent that whitens flour pigments and then breaks down mainly to benzoic acid and oxygen.
How to prevent bleached eyebrows benzole peroxide?
Because it’s a bleaching oxidizer, keep products away from hair/eyebrows, apply carefully, use a barrier (e.g., petroleum jelly) along the hairline, and rinse hands and any residue off promptly.
How to use benzole peroxide?
In food processing, small regulated amounts are uniformly blended into flour to bleach and mature it; for topical acne products, follow the label and start with lower strengths due to irritation and bleaching risk.
What store sells benzole peroxide shampoo?
Benzoyl peroxide is uncommon in human shampoos (it can bleach hair) and is mainly sold as acne washes at pharmacies or online; as E928 it’s an industrial flour-bleaching aid, not a consumer shampoo.
