Answer: The list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.
Explanation:
The amount of energy required to remove the most loosely bound electron from an isolated gaseous atom or ion is called ionization energy.
Element with a half-filled orbital requires much more energy to remove an electron. This is because element with a half-filled electronic configuration is the most stable in nature.
More stable or tightly electrons are bound to the nucleus of an atom more will be its ionization energy. This also means that smaller is the atom higher will be its ionization energy.
When we move from top to bottom in a group the size of atom increases and the attraction between nucleus of atom and its valence electrons decreases. Hence, less will be the ionization energy.
Therefore, ionization energy decreases on moving down a group.
So, the given elements Phosphorus, Bismuth, Arsenic, Antimony, Nitrogen are all group 15 elements. Hence, decreasing order of their ionization energy is as follows.
Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth
Thus, we can conclude that the list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.
Answer:
THE HEAT CAPACITY OF THE CALORIMETER IS 3666.67 J/C
Explanation:
Mass = 2 g
Temperature difference = 32 C - 29 C = 3 C
Heat of combustion = 11 kJ/g
Heat capacity of the calorimeter = unknown
It is important to note that the heat of combustion of the reaction is the heat absorbed by the calorimeter in raising the mixture by 3 C
So therefore,
Heat = heat capacity * temperature difference
Heat capacity = Heat / temperature difference
Heat capacoty = 11 000 J / 3 C
Heat capacity = 3666.67 J/ C

The answer is electrolytes. Strong electrolytes like strong acids, strong bases and salts dissociate completely into ions when dissolved and no neutral molecules are present in their solution. Weak electrolytes like weak acids and weak bases do not completely ionize in water and some neutral molecules are present in their solution, while nonelectrolytes do not dissociate into ions when in solution at all.
