A adult pushing a car and a child pushing a car. Are two unbalanced forces
Using the formula density = mass ÷ volume, I got my answer as 10g/cm^3 or 10g/mL
A neutral atom in its ground state contains 28 electrons. this element is considered a <span>transition </span>element, and has 8 electrons in orbitals with l = 2.
Electron configuration: ₂₈X 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s².
l is azimuthal quantum number, l = 2 describes d orbital. There is eight electrons in 3d orbital.
The initial state of the compound Br2 is liquid. The final
state is then solid. We know for certain that the liquid state has higher energy
as compared to solid state. Due to this fact, Br2 must release energy to be in
solid form. Therefore, the change in enthalpy is:
ΔH = -7.4 kcal/nil
