calculate the amount of heat transferred when 46.0 g of {rm{CH}}_3 {rm{OH}}(g) is decomposed by this reaction at constant pressure.
The molecule, atracurium, is a very complex drug. Atracurium exhibits a very short half-life (20-min). The products of the fastest inactivation process are shown.
the titration of acetic acid with sodium hydroxide can be expressed as the combination of two reactions: the acetic acid reacting with water, and the sodium hydroxide reacting with hydronium ion.
the absorbance of the solution was found to be .5528. Based on the calibration curve of Y=26.1x + .081 (where absorbance is on y axis and concentration of product C is on the x axis) determine the equilibrium concentration of C, then using an ICE ..
