 The ionization energy increases because the ratio of the protons to electrons increases. It is quantitatively expressed in symbols as X + energy → X+ + e−.

Answer:

Explanation:  Ionization energy is the removal of an electron from the outermost shell of the gaseous atom.

 X(g) \rightarrow  X^{+}(g) + e^{-}

When we remove one electron, the species acquire a positive charge because the number of protons has been increased than the number of electrons . In reference to this, the nucleus would hold its grip to the valence shell more than before due to the electrostatic forces of attraction.

Thus, due to this electrostatic forces of attraction, it will become difficult to remove an electron from the last shell.

Thus ionization energy will increase on removal of successive electrons .

Based on your knowledge of energy conservation, which of the following statements is true?
Julli [10]
C. both a and b

If a light bulb can last longer with the same amount of energy it is given, that means it can use less energy to do the same job compared to one that does not last longer with the same amount of energy it is given. It is much like how a more fuel efficient car will be able to go farther on the same tank of gas, but if you pair it with a car that doesn't have as great of an mpg, when they go the same distance, the car with the greater mpg spends less fuel.

If you don't have to use the energy when you aren't utilizing it, then you can conserve the energy for when you do need it.

What does Gibbs free energy depend on? O A. It depends on the rate and quantity of the reaction. O B. It depends on the activati
Oksana_A [137]

Answer:

C: It depends on the entropy and enthalpy of the reaction.

Explanation:

Gibbs free energy is defined as the maximum amount of non-expansion work that can be gotten from a closed system. Now this work is usually done in place of the system’s internal energy and Energy that is not extracted as work is usually exchanged with the immediate surroundings in the form of heat.
