Answer is: Sb(g) → Sb⁺(g) + e⁻.
Neutral atom in gas state lose one valence electron and become cation with postive charge.
<span>The first ionisation energy is the energy required to remove one mole of the valence electrons from one mole of gaseous atoms to produce one mole of gaseous ions each with a charge of 1+.</span>
<span>Most metals have strong
metallic bond, because strong electrostatic attractive force
between valence electrons (metals usually
have low ionization energy and lose electrons easy) and positively
charged metal ions.

Answer:
Attractions between molecules cause a reduction in volume
Explanation:
This is a very important concept of the ideal gas law application. The ideal gas law applies when several conditions are met:
- the size of individual atoms or molecules should be negligible, so that we may assume that the volume of the gas is equal to the volume of a container;
- the attractions between individual atoms should also be negligible, so that on average the gas fills the whole container and the volume of a container would be equal to the volume of the gas.
Therefore, the ideal gas law applies best in scenarios where we have a high temperature and a low pressure (or large volume). The larger the volume gets, the more negligible is the size of a molecule compared to the size of a container.
Speaking of temperature, the greater the temperature, the higher the kinetic energy of the gas molecules, so that the average distances between them increase and the attraction forces are minimized.
However, having a low temperature would cause the molecules of a gas move slower and attraction forces would be more significant due to lower average distances between the molecules.
The volume of 0.160 m Li2S solution required to completely react with 130 ml of 0.160 CO(NO3)2 is calculated as below
write the reacting equation
Co(NO3)2 + Li2S = 2LiNO3 + COS
find the moles of CO(NO3)2 = molarity x volume
= 130 ml x 0.160=20.8 moles
since the reacting moles between CO(NO3)2 to LiS is 1:1 the moles of LiS is also 20.8 moles
volume of Lis is therefore = moles of Lis/ molarity of LiS
= 20.8/0.160 = 130 Ml
100.0g x 4.184J/g/°C x 78°C ΔT = 32,645.2 Joules.
