Water vapor
Explanation:
The magma consist of dissolved gases when these gases produce the force the volcanic eruption take place. The volcanic gases comes out and their volume is increased tremendously. The gases present in volcano are listed below:
The volcanic gases consist of water vapors, carbon dioxide and sulfur.
These three re the primary gases but the water is present in higher amount.
The percentage of water is 60%.
The carbon dioxide present in 10-40%.
Other gases present in valcano are nitrogen, argon, helium, neon methane and hydrogen.
+2 is the oxidation number for Zinc
<span>Oxidation Number for a Transition metal = Number of Unpaired d-electrons + Two s-electrons
</span>[Ar]4s2 3d10 is the electron configuration for zinc. The d-block is full with 10 electrons meaning there are no unpaired d-electrons, so the oxidation number is 0 unpaired d-electrons + 2 s-electrons = +2
