Question

The primary gas in a volcano is: carbon dioxide, sulfur dioxide, water vapor, nitrogen.

Answer 1

The primary components in volcanic gas are water vapor, carbon dioxide and sulfur (either sulfur dioxide or hydrogen sulfide). But you can also find nitrogen, argon, helium, neon, methane, carbon dioxide and hydrogen. Approximately 60% of total emissions released by volcanoes is water vapor, and carbon dioxide accounts for 10 to 40% of emissions.

Step-by-step explanation:

Answer 2

Water vapor

Explanation:

The magma consists of dissolved gases when these gases produce the force the volcanic eruption takes place. The volcanic gases come out and their volume is increased tremendously. The gases present in the volcano are listed below:

The volcanic gases consist of water vapors, carbon dioxide, and sulfur.

These three are the primary gases but the water is present in a higher amount.

The percentage of water is 60%.

The carbon dioxide present in 10-40%.

Other gases present in volcanos are nitrogen, argon, helium, neon methane, and hydrogen.

Hope this helps, Let me know if I am wrong ( I am pretty sure that am not) but let me know anyway..., OH! and Good LUCK! :D ;P
