Why is Venus's atmosphere thick?

Limestone is just 10% of the sedimentary rock, so there are probably a lot more carbon in the crust. Such carbon containing compounds releases carbon at high temperatures, thus they are already decomposed on Venus. As strange as it may sound, the higher temperature of Venus is the cause of the dense atmosphere. What is Jupiter's atmosphere made of? Atmosphere and Weather: Jupiter's extremely dense and relatively dry atmosphere is composed of a mixture of hydrogen, helium and much smaller amounts of methane and ammonia. The same mixture of elements which made Jupiter also made the Sun.

Subsequently, what is mercury's atmosphere composition in in percentages?

Nitrogen and oxygen are two gases that make up the majority of Earth's atmosphere, and they appear in Mercury's as well.

Correspondingly, can you breathe on mars?

Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
