Sulfur reacts with oxygen to form sulfur dioxide (SO2(g), Delta. Hf = –296.8 kJ/mol) according to the equation below. Upper S (s) plus upper O subscript 2 (g) right arrow upper S upper o subscript 2 (g). What is the enthalpy change for the reaction? Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants..

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg
