WebThe valency of H in HCl ,H2 and H2O are respectively +1 , +1,+2 . 1.) HCl As we know Cl is in 17th group of periodic table. So it require one electron to complete its valence shell.Addition to that its electronegativity is higher than Hydrogen. So, Cl gains an electron from H. Hence, Valency of H in HCl is +1. 2.) H2 Web13 apr. 2024 · Gentian violet is a triphenylmethane dye, which has been widely used in papermaking, textile and other fields. However, the industrial residue of gentian violet will be discharged into the ecosystem with wastewater, thus posing a threat to human health, such as teratogenic, carcinogenic and so on (Sekar et al., 2024).At present, many treatment …
Web30 jan. 2024 · Covalent bonding occurs when pairs of electrons belong shared by nuclei. Atoms will covalently borrow with other atomkerne in place to gain further stability, which is gained by forming a full electrons shell. By … WebThe first step in drawing the Lewis dot structure for ethane ( C2H6 ) is to determine how many valence electrons are available for the molecule. This means that the Lewis dot structure for C2H6 must account for 14 valence electrons, either through bonding between atoms, or through lone pairs. Hope it helps. Staysafe.
