Answer:
9.39 × 10²² molecules
Explanation:
We can find the moles of gases (n) using the ideal gas equation.
P . V = n . R . T
where,
P is the pressure (standard pressure = 1 atm)
V is the volume
R is the ideal gas constant
T is the absolute temperature (standard temperature = 273.15 K)

There are 6.02 × 10²³ molecules in 1 mol (Avogadro's number). Then,

A chemical reaction is a reaction that changes the molecular structure and is normally irreversible.
We use radiowaves all the time because they are harmless. (as far as we know, although bees are dying and know one knows why, perhaps all the waves we use do have a negative effect)
Can I get a brainliest, please?
I believe that's is answer C because your ask about and increasment on the velocity in this observation
3 covalent bonds (there are 2 electrons in the first orbital and 5 in the second. You still have room for three more)
