Answer:
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.
Answer:
The final volume will be "70.08 mL".
Explanation:
The given values are:
Molar mass,
M1 = 548 nM
or,
= 
M2 = 484 nM
or,
=
Volume,
V1 = 61.9 mL
V1 = ?
By using the expression, we get
⇒ 
or,
⇒ 
By substituting the values, we get



E- is a negative electron
The mass of the atom is equal to the sum of the number of protons and the number of neutrons. In a neutral atom, the number of protons is equal to the number of electrons. The atomic number meanwhile of an atom is equal to the number of protons of the atom.
