They hold molecular bonds together in solds and liquids.
Answer:
Atomic Particles
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge).
Answer:
6.5 liters.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If P and T are constant, and have different values of n and V:
<em>(V₁n₂) = (V₂n₁)</em>
<em></em>
V₁ = 4.5 L, n₁ = 0.80 mol,
V₂ = ??? L, n₂ = 0.35 + 0.80 = 1.15 mol.
- Applying in the above equation
<em>(V₁n₂) = (V₂n₁)</em>
<em></em>
<em>∴ V₂ = (V₁n₂)/n₁ </em>= (4.5 L)(1.15 mol)/(0.8 mol) = <em>6.469 L ≅ 6.5 L.</em>
<em></em>
<em>So, the right choice is: 6.5 liters.</em>
