Question

Hydrogen is a gas that burns with a pop sound.
(a) True
(b) False

Answer 1

Hint: Hydrogen is a metal and when this is made to react with the non-metal of the p-block i.e. the oxygen atom, it undergoes explosion and burns with a sound. From this you can easily identify whether the given statement is correct or not.

Complete step by step answer:
First let's discuss hydrogen. Hydrogen is an alkali metal and comes under the category of the s-block elements and has the atomic number as 1 and mass number also as 1. It is present in the 1st period and in the 1st group of the periodic table.
The shorthand notation of hydrogen atom is $H$.
In its outermost valence shell , it consists of one electron and has a tendency to gain the electron and to acquire the stable electronic configuration of the nearest noble gas helium
Hydrogen gas is colorless, odorless in nature and it is lighter than the air but is insoluble in water.
.When hydrogen gas comes in contact with the oxygen gas, it results in the explosion and hydrogen burns with the pop sound.
So, thus Hydrogen is a gas that burns with a pop sound is true.

Hence, option (a) is true.

Note: Hydrogen gas is used as a reducing agent in the laboratories in the synthesis of many organic compounds such as the formation of the ammonia. It is also used as fuels in the rockets and in industries too.
