the same
Explanation:
Within the nucleus of individual atoms of the same element, the proton number is the same.
All atoms of the same kind from the same element have the same number of protons.
The number of protons does not change, it remains fixed after a chemical reaction.
Different elements have different number of protons that typifies and makes them unique.
But atoms of the same element have the same number of protons in them.

Hey there!
Label A: Sublimation
Label B: Condensation
Label C: Melting
Remember sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Condensation is the conversion of a vapor or gas to a liquid. Melting is becoming liquefied by heat.
Hope this helps!
Answer:
The exact molecular mass is 18.01528 g/mol
Explanation:
Find this by adding the molecular masses of two hydrogen atoms and one oxygen atom.
Hot air balloons have hot air inside them, which is less dense as the air around it. Thus it rises. A cold air balloon would sink because the air would be more dense than the air around it. Also, the balloon’s volume would vary in size depending on the weight of the balloon.
