Unformatted text preview: hydrogen chloride (HCl) and hydrogen fluoride (HF). There are carbon monoxide , water vapor and molecular oxygen as well.   Hydrogen is in relatively short supply in the Venusian atmosphere. A large amount of the planet's hydrogen is theorised to have been lost to space,  with the remainder being mostly bound up in sulfuric acid (H 2 SO 4 ) and hydrogen sulfide (H 2 S). The loss of significant amounts of hydrogen is proved by a very high D /H ratio measured in the Venusian atmosphere.  The ratio is about 0.025, which is much higher than the terrestrial value of 1.6×10 −4 .  In addition, in the upper atmosphere of Venus D/H ratio is 1.5 higher than in the bulk atmosphere. ...
