Which statement describes an intensive property of matter

Answers

Answer 1

Answer:

An intensive property is a property that does not depend on the amount of the substance in a system being measured. Examples are density and color. The opposite is called extensive where the properties depends on the amount of a substance.

Process in which water vapor turns to liquid

Answers

Explanation:

When water is collected from vapour form to liquid form then this process is known as condensation.

For example, water evaporated from the atmosphere reaches to the clouds and it gets converted into liquid form and again reaches to Earth in the form of rain.

Thus, we can conclude that process in which water vapor turns to liquid is called condensation.

In the amtmosphere this water vapor cools and turns back to liquid for forming clouds
this process is called condensation. When it cant hold on much longer it will turn into rain or snow.

What is the word equation for molecules of magnesium reacting with molecules of oxygen to produce molecules of magnesium oxide?magnesium + magnesium oxide = oxygen
magnesium + oxygen =magnesium oxide
magnesium oxide = magnesium
magnesium + oxygen magnesium + oxygen

Answers

Answer: magnesium + oxygen =magnesium oxide

Explanation: When Magnesium reacts with the molecules of oxygen , Magnesium oxide is produced.

Mg (s) + O (g) → MgO (s)

In this equation, both magnesium and oxygen are present in its elemental state.

Magnesium is present in solid form and oxygen is present in gaseous form.

The Bonding between the Magnesium and the oxygen is purely IONIC bonding as Magnesium loses its 2 valence electrons to complete its octet and oxygen gains its electrons to make its electron count 8 in the valence shell.

Answer: (B) Magnesium + oxygen =magnesium oxide

Explanation:

Which ion was formed by providing the second ionization energy to remove an electron? Ca2+ N3– Fe3+ S2–

Answers

Answer:

Ca²⁺

Explanation:

Ionization energy is defined as the minimum amount of energy required to knock out the electron from valence shell of an atom in its gaseous state. While, second Ionization energy is defined as the amount of energy required to knock out the second electron from an ion containing +1 charge in gaseous state.

Among given options Ca²⁺ is the correct choice because the calcium has lost two electrons i.e. first electron was removed by providing first ionization energy i.e.

Ca + 1st IE → Ca¹⁺ + 1 e⁻

and second electron is was removed by providing second ionization energy i.e.

Ca ¹⁺ + 2nd IE → Ca²⁺ + 1 e⁻

$\boxed{{\text{C}}{{\text{a}}^{{\text{2 + }}}}}$ is formed by providing the second ionization energy to remove an electron.

Further Explanation:

The energy that is needed to remove the most loosely bound valenceelectrons from the isolated neutral gaseous atom is known as the ionization energy. It is denoted by IE. The value of IE is related to the ease of removing the outermost valence electrons. If these electrons are removed so easily, small ionization energy is required and vice-versa. It is inversely proportional to the size of the atom.

Ionization energy is further represented as first ionization, second ionization and so on. When the first electron is removed from a neutral, isolated gaseous atom, the energy needed for the purpose is known as the first ionization energy, written as ${\text{I}}{{\text{E}}_{\text{1}}}$ . Similarly, when the second electron is removed from the positively charged species (cation), the ionization energy is called the second ionization energy $\left( {{\text{I}}{{\text{E}}_{\text{2}}}} \right)$ and so on.

The neutral atom corresponding to ${\text{C}}{{\text{a}}^(2 + )}$ is calcium. If second ionization energy is supplied to calcium atom, it results in the removal of two electrons and thus ${\text{C}}{{\text{a}}^(2 + )}$ is formed. So ${\text{C}}{{\text{a}}^(2 + )}$ can be formed by providing second ionization energy. to the neutral atom.

The neutral atom corresponding to ${{\text{N}}^(3 - )}$ is nitrogen. If second ionization energy is supplied to nitrogen, it results in the formation of ${{\text{N}}^(2 + )}$ , not ${{\text{N}}^(3 - )}$ . So ${{\text{N}}^(3 - )}$ cannot be formed by providing the second ionization energy to the neutral atom.

The neutral atom corresponding to ${\text{F}}{{\text{e}}^(3 + )}$ is iron. If second ionization energy is supplied to the iron atom, it results in the formation of ${\text{F}}{{\text{e}}^(2 + )}$ , not ${\text{F}}{{\text{e}}^(3 + )}$ . So ${\text{F}}{{\text{e}}^(3 + )}$ cannot be formed by providing the second ionization energy to the neutral atom.

The neutral atom corresponding to ${{\text{S}}^(2 - )}$ is sulfur. If second ionization energy is supplied to the sulfur atom, it results in the formation of ${{\text{S}}^(2 + )}$ , not ${{\text{S}}^(2 - )}$ . So ${{\text{S}}^(2 - )}$ cannot be formed by providing the second ionization energy to the neutral atom.

Therefore, the only ion that can be formed by supplying the second ionization energy is ${\text{C}}{{\text{a}}^(2 + )}$ .
