A pure substance is also known as chemical substance, it is a form of matter having constant chemical composition and characteristic properties.

Also a pure substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds.

A mixture of milk and water (tea) can be separated by filtration (physical method).

A mixture of of sugar and water can be separated by distillation (physical method).

Also a casserole, pomegranate juice are separated using physical methods.

However, carbon monoxide constant chemical composition and characteristic properties, and it cannot be separated by physical method.

Which compound contains both covalent and ionic bonds? <br> a. NCl3 b. NaF c. HCN d. NH4OH
Marina86 [1]
<h2>NH_4OH contains both covalent and ionic bonds.</h2>

Explanation:

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal.

a. NCl_3 contain covalent bonds as they are made up of non metals only.

b. NaF contain ionic bonds as they are made up of sodium metal and fluorine non metal.

c. HCN contain covalent bonds as they are made up of non metals only.

d. NH_4OH contain  ionic bonds between NH_4 and OH and covalent between N and H in NH_4^+
