<u>Answer:</u>

<u>For 1:</u> The correct answer is Option D.

<u>For 2:</u> The correct answer is Option B.

<u>For 3:</u> The correct answer is Option A.

<u>Explanation:</u>

<u>For 1:</u>

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.
  • When an atom gains electrons, it results in the formation of negative ion known as anion.

We are given:

An ion carrying a charge of +3. This means that an element is loosing 3 electrons, so it has 3 valence electrons.

The elements that belong to Group 13 of the periodic table has 3 valence electrons and form +3 ions.

Hence, the correct answer is Option D.

  • <u>For 2:</u>

For the given options:

<u>Option A:</u> Covalent bond is defined as the bond which is formed when sharing of electrons takes place between the atoms. This is usually formed between two non-metals.

<u>Option B:</u> Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom. The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

<u>Option C:</u> A polar covalent bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: CO_2,NO_2 etc..

<u>Option D:</u> Hydrogen bonding is defined as the intermolecular force having partial ionic-covalent character. This type of bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).

Group 2 elements are considered as metals having general electronic configuration as ns^2

They will loose 2 electrons to form X^{2+} ions and thus tends to form ionic bonds.

Hence, the correct answer is Option B.

  • <u>For c:</u>

When a positive ion gains electrons equal to the charge on the ion, the positive charge will get neutralized by the negative charge.

X^{2+}+2e^-\rightarrow X

The ion will loose its charge and will form a neutral atom.

Hence, the correct answer is Option A.

Litmus paper is often used to determine the range of pH of an aqueous solution. Litmus paper specifically contains 10-15 natural dyes, in the presence of acidic solution it turns red, it turns purple when the solution is neutral and blue when dealing with basic solutions. Red litmus paper stays red for a neutral and acidic solution but changes to blue in the presence of alkaline solutions. On the other hand, blue litmus paper turns red when a solution is acidic but stays blue for neutral and alkaline solutions. Since the paper turns purple in the presence of solution 1 we know that is neutral, meanwhile, since it turns blue for the second solution we know that solution II is a base correct answer is C

CO_2 sublimes readily at 25°C. Which properties are usually associated with a compound that undergoes this kind of change?
antoniya [11.8K]

Explanation:

Sublimation is defined as a process in which solid state of a substance directly changes into vapor or gaseous state without undergoing liquid phase.

For example, naphthalene balls show sublimation at room temperature.

As this process does not cause any change in chemical composition of a substance. Hence, it is known as a physical process.

Similarly, when CO_{2} sublimes readily at 25^{o}C. This shows change in physical state of carbon dioxide is taking place, i.e, from solid to gaseous phase.

Thus, we can conclude that when CO_{2} sublimes readily at 25^{o}C then it means physical properties are usually associated with a compound that undergoes this kind of change.
