Oxygen has two allotropic forms, diatomic (O2) and triatomic (O3, ozone). The properties of the diatomic form suggest that six electrons bond the atoms and two electrons remain unpaired, accounting for theparamagnetismof oxygen. The three atoms in theozonemoleculedo not lie along a straight lin...
Hydrogen sulfide (H2S) is now considered to be a signalling molecule in a range of organisms. In animals and plants there are characterised mechanisms for generation and removal suggesting that it can be made and have an effect when required. In plants H2S has been found to help mediate a ...
Electronegativity: A numerical method for indicating the relative tendency of an atom to attract the electrons that make up a covalent bond. Hydrogen bond: A chemical bond formed between two atoms or ions with opposite charges. Ionic bond: A chemical bond formed when one atom gains and a ...
Find the average time τ between oxygen molecule collisions at p = 1 μPa and T = 300 K. The effective diameter of oxygen molecule d is 0.36 nm, mole mass M = 32 × 10–3 kg/mol. 3.43 Determine the ratio (η1/η2) of the viscosity coefficients of oxygen and hydrogen at similar...
