The concentration of 
in the stack gas = 12 ppmv
That means 12 L of is present per 
The given temperature is 273 K (0 C) and pressure is 1 atm. At these conditions, 1 mol of gas would occupy,
V = 22.4 L
1 mol

Answer:
In order for frost to be formed, you would need high humidity, below-freezing temperatures, a clear sky, and a calm wind. Also, note that frost mostly occurs on a surface that is solid, so I would also put in a hard surface to the answer.
Explanation:
You need the hard surface so that the frost can form, otherwise it would become something like a cloud.
You need high humidity so that there is lots of water to form on your solid surface.
You need below-freezing temperatures so that the water can freeze.
The other things are just from what the Internet told me.

Answer:
A)Protons and electrons
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
when an atom lose or gain the electron ions are formed and number of protons and electrons no longer remain the same.
For example:
An atom of sodium when lose one electron it form positive ion. The number of electrons became 10 and number of protons remain 11.
Na → Na⁺ + 1e⁻
