Hydrogen | MCQs

Explanation

Hydrogen is the most abundant element in the universe.

it is about 75 percent of its normal matter and was created in the Big Bang.

Additional information:

Oxygen is the most abundant element in the earth`s crust.

Calcium is the most abundant mineral in the human body.

Explanation

Hydrogen and helium are the two lightest gases.

Helium is the second most abundant element in the universe, after hydrogen.

Helium has monatomic molecules.

It is the lightest of all gases except hydrogen.

Hydrogen is the lightest gas known.

It provides the maximum lift for balloons due to its very low density.

Explanation

A hydrogenation reaction occurs when vegetable oils are converted to fats.

The double bonds of vegetable oils are broken down resulting in a saturated fat i.e. ghee.

Explanation

Henry Cavendish - He discovered hydrogen gas and the composition of water contains two parts of hydrogen and one part of oxygen.

Symbol: H

Atomic mass: 1.00784 u

Atomic number: 1

Named by: Antoine Lavoisier (1783)

Explanation

The core principle behind a hydrogen bomb is the fusion of light atomic nuclei.

Specifically isotopes of hydrogen (deuterium and tritium), under extremely high temperatures and pressures. 

Explanation

• Edward Teller is often referred to as the “father of the hydrogen bomb.”

•  After the Soviet Union detonated its first atomic bomb in 1949, Edward Teller worked to convince President Truman to develop a crash program for the hydrogen bomb, which he believed was feasible.

• Edward Teller was a Hungarian-American theoretical physicist

Explanation

Germany was the first country to introduce a hydrogen-powered train.

The train, called the Alstom Coradia iLint.

It was developed by French company Alstom.

It has a record range of 1,175 kilometers without refueling.

China became the first country in Asia.

It is the second in the world to launch hydrogen-powered trains.

Chinese trains have a top speed of 160 kilometers per hour.

It can run for 600 kilometers without refueling.

Explanation

A state-of-the-art liquid hydrogen tanker readied for loading in Australia on 21-01-2022 ahead of shipment to Japan, in what Australian PM described as a “world first” trial of the technology.

Explanation

The world's largest low-carbon hydrogen facility will be set up in American state of Texas. 

Set to be set up in 2029.

Explanation

In 1-butyne, the hydrogen is attached to a carbon with a triple bond (sp hybridization), which makes it more acidic because the carbon can better stabilize the negative charge formed after losing the hydrogen ion.
