A sample of hydroiodic acid has a concentration of 1.46 M and a density of 1.25 g/mL. IF 50.0 ml s of this sample is removed and diluted with 155 ml.s of water (density = 1.00 g/mL), what is the molarity of the new sample? The decomposition of acetaldehyde (CH:CHO) is proposed to occur via a two-step mechanism. Step 1: CH3CHO + 12 + CH3 + HI + CO Step 2: CHI + HI – CH4 + 12 Which species...
