H2SO4 fully dissociates into ions (strong acid). It is diprotic therefore concentration of H+ ions is twice that of the acid = 0.4 M. pH = -log[H+] = -log[0.4] ...
AsH3 is a larger molecule than PH3 as As is lower down the periodic table, so has a higher atomic number so more electrons. Therefore AsH3 has more electrons than PH3 mean...
Carbon Dioxide consists of 1 carbon atom covalently bonded to two oxygen atoms.Carbon is in group 4 and so has 4 electrons in its outer shell.Carbon shares two pairs of electrons with each of the oxygen a...
Alkenes decolourise bromine water (orange/brown to colourless) while alkanes cause no change in colour. An electrophilic addition reaction occurs with the alkene. In a reaction between et...
usually covalent structures cannot conduct electricity but graphene is one of the exceptions and this is due to its structure and bonding. It is a giant covalent 2D molecule, hexagonal in shape with 3 cov...
