Answers

The smallest possible particle of an element is a atom. An electron has a charge identical to that of of a proton, but with the opposite sign.

What is atom?

The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. Electric forces, which link electrons towards the nucleus of atoms, cause them to be drawn to any positive charge.

Space makes up the majority of an atom. The remainder is made up of a cloud of negatively charged electrons around a positively charged nucleus made up of protons and neutrons. An electron has a charge identical to that of of a proton, but with the opposite sign.

Therefore, an electron has a charge identical to that of of a proton, but with the opposite sign.

Which compound becomes less soluble in water as the temperature of the solution is increased?(1) HCl (2) KCl (3) NaCl (4) NH4Cl

Answers

Answer: Option (1) is the correct answer.

Explanation:

Compounds in which atoms transfer electrons result in the formation of ionic bond. Whereas when atoms in a compound share electrons then they result in the formation of covalent compounds.

Also, it is known that like dissolves like. Hence, water being an ionic compound itself dissolves other ionic compounds.

Thus, out of the given options HCl is a covalent compound, therefore, HCl is the compound that becomes less soluble in water as the temperature of the solution is increased.

HCI are less soluble in water as the temperature of the solution is increased.
