As the air molecules move through the valve they have friction as they hit the walls, and its this friction that causes it to heat up.
Answer:
They will create an ionic bond.
Explanation:
The atom with the one valence electron will lose its one, because it's a metal and metals will lose electrons to become stable. The nonmetal (with 7 valence electrons) will gain that electron, therefore creating a stable octet for the nonmetal, making the compound stable.
Answer:
D. Element.
Explanation:
Atoms form elements. Elements form molecules. Molecules form compounds.
Answer:
23 atm
Explanation:
Step 1: Given data
- Initial volume (V₁): 2.5 L
- Initial pressure (P₁): 90 atm
Step 2: Calculate the final pressure of the gas
If we assume constant temperature and ideal behavior, we can calculate the final pressure of the gas using Boyle's law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 90 atm × 2.5 L / 10 L = 23 atm
As expected, since the volume increased, the pressure decreased.
