The balanced reaction between Hydrogen and Oxygen to form Water:
2H₂ + O₂ → 2H₂O
From the equation it already states that:
2 molecules of Hydrogen H₂ are needed to produce 2 molecules of Water H₂O
So the answer is 2.
Option B.
Most metallic: Ge
Largest atomic radius: Bi
Highest ionization energy: Cl

The pressure is directly proportional to temperature (when the pressure decrease the temperature decrease too). Because the air parcel expands so the molecules will not interact with each other as much.
The energy of the particles does not change but the fact that the particles are more spaced out means the parcel is cooler.
so now, the warmer a parcel of air the more water vapor it can hold. so, if a parcel of air cools it's ability to hold water vapor drops and if it drops to a low enough point that is when the water vapor will condense and turn back into liquid water. This is how clouds and precipitation form on the the windward side of the mountain.
Answer:
0,1,2,3
Explanation:
for the given value of n , l = 0 to n-1
so if n = 4
l = 0 to 4-1
