Answer:
Ionization energy of the metal and electron affinity of the nonmetal
Explanation:
An ionic bond is formed when a metal transfers electrons to a nonmetal.
M· + A ⟶ M⁺ + ·A⁻
The two main factors affecting this process are the
- Ionization energy of the metal
- Electron affinity of the nonmetal
1. Ionization energy
The lower the ionization energy of the metal, the more likely it is able to donate an electron.
2. Electron affinity
The higher the electron affinity of the nonmetal, the more likely it is to accept an electron,
3. Periodic trends
(a) Ionization Energy
Ionization energy increases from bottom to top and from left to right in the Periodic Table.
Thus, the atoms with the lowest ionization energy are in the lower left corner of the Periodic Table.
(b) Electron affinity
Electron affinity increases from bottom to top and from left to right in the Periodic Table.
Thus, the atoms with the highest electron affinity are in the upper right corner of the Periodic Table.
D. Even though the temperature is the same, container B has more thermal energy, since it has more liquid than container A.
<u>Explanation:
</u>
Whenever there is an increase in the volume of the pink liquid, it is due to the increase in temperature.
When the temperature increases, the molecules move farther apart as much as possible.
When the molecules moves apart from each other and collide with each other, so that its kinetic energy also increases, So thermal energy of the container B is more compared to the container A.
<em>mC₃H₈: 44 g/mol</em>
<em>mCO₂: 44 g/mol</em>
---------------------
C₃H₈ + 5O₂ ----> 3CO₂ + 4H₂O
44g (44·3)g
44g C₃H₈ ------ 132g CO₂
15g C₃H₈ ------ X
X = (15×132)/44
<u>X = 45g CO₂

5. They were packaged at a higher pressure on the ground, thus causing the gas inside the packages to expand in the sky where the jet is at a lower pressure.
Explanation:
According to Boyle's law, the pressure of a given mass of gas is inversely proportional to it volume at constant temperature
P₁·V₁ = P₂·V₂
At the factories, the peanuts are packaged at atmospheric conditions whereby P₁ = 1 atm, however, the pressure of the air in the atmosphere decreases with altitude as such the pressure in the airplane jet is about a fraction of hat on the ground by about a factor of 0.7.
Therefore P₂ = 0.7 atm and we have
V₂ = P₁·V₁/P₂ = 1 atm×V₁/0.7 atm = 1.43·V₁
The volume increases at high altitudes
