A. Sodium
idk if it's right or not, but hope this helped a little.
Answer:tetrahedral
Explanation:
According to Valence Shell Electron Pair Repulsion Theory (VSEPR). The number of electron pairs on the valence shell of the central atom in a molecule influences the shape of that molecule. Four electron pairs around the central atom of a molecule leads to a tetrahedral geometry as predicted by VSEPR.
a. P=0.971 atm=737.6 mmHg
b. n=2.88 x 10⁻³
<h3>Further explanation
</h3>
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
A. vapor pressure of water at 22.5 = 20.4 mmHg
Pt=P H₂ + P H₂O
758 = P H₂ + 20.4
P H₂=737.6 mmHg=0.971 atm
B.Ideal gas Law = PV=nRT
P = 0.971 atm
V = 72 ml = 0.072 L
R = 0.082 L/atm mol
T = 22.5 + 273.15 =295.65
Answer:
A
Explanation:
I think it's pressure. Using the process of elimination, sediment is the matter that's on the bottom of a liquid or solution, deposition is the process of deposing, eruption is the process of erupting, and pressure's formula is force/area, so pressure is the answer.
