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^+

The properties of an unknown substance can be compared to the properties of a known substance to identify the unknown substance.
Nitella [24]

Answer:  Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Explaination:

By using Physical properties unknown substance can be identified as it involves determination of a substance with out changing their composition or property include color, odor, taste, density, melting point etc.

What are the difference between physical and chemical property ?

Chemical properties can be observed or measured when a substance undergoes any type of changes chemically while Physical properties can be observed without changing anything.

In chemical property, chemical reaction is conducted to show the property of the substance while in physical property No chemical reaction occur.

Chemical properties related to chemical bonds while Physical properties do not have such a relationship.

Chemical properties include radioactivity, toxicity, flammability, heat of combustion,  etc. while physical properties include Molecular weight, boiling point, melting point, freezing point, volume, mass, length, density shape, solubility, etc.
