<span>Charles' law says "at a constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature".
V </span>α T
Where V is the volume and T is the temperature in Kelvin of the gas. We can use this for two situations as,
V₁/T₁ = V₂/T₂
V₁ = 2.00 L
T₁ = 40.0 ⁰C = 313 K
V₂ = ?
T₂ = 30.0 ⁰C = 303 K
By applying the formula,
2.00 L / 313 K = V₂ / 303 K
V₂ = (2.00 L / 313 K) x 303 K
V₂ = 1.94 L
Hence, the volume of the balloon at 30.0 ⁰C is 1.94 L

In complex compounds coordination number is the number of atoms or polyatomic ions surrounding the central metal. In given statement the coordination number given is 6, means there are 6 ligands surrounding the metal atom, and the ligands given are only NH₃, so 6 NH₃ molecules are surrounding the Cobalt atom. Hence,
[Co (NH₃)₆]
As, NH₃ is neutral so the charge on sphere will be the charge on Co, as charge given in statement id +3 so,
[Co (NH₃)₆]³⁺
Name of this complex is as follow,
Hexaamminecobalt (III) Ion
Answer: Electrons in bonding orbitals stabilize the molecule because they are between the nuclei. They also have lower energies because they are closer to the nuclei. Antibonding orbitals place less electron density between the nuclei. The nuclear repulsions are greater, so the energy of the molecule increases.
