An environmental engineer analyzes a sample of air contaminated with sulfur dioxide. to a 500.−ml sample at 700. torr and 38°c, she adds 18.25 ml of 0.01017 m aqueous iodine, which reacts as follows: so2(g) + i2(aq) + h2o(l) → hso4−(aq) + i−(aq) + h+(aq)[unbalanced] excess i2 reacts with 11.37 ml of 0.0105 m sodium thiosulfate: i2(aq) + s2o32−(aq) → i−(aq) + s4o62−(aq)[unbalanced] what is the volume % of so2 in the air sample? % so2

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
