Deuterium is also known as _________

Detailed Solution for Test: Hydrogen (Basics) (Old NCERT) - Question 7

Deuterium is one of the two stable isotopes of Hydrogen (the other one being the protium), it is known as heavy hydrogen as it has one neutron and one proton. The radioactive isotope of hydrogen is tritium.

Test: Hydrogen (Basics) (Old NCERT) - Question 8

What is the half-life of atomic hydrogen?

Detailed Solution for Test: Hydrogen (Basics) (Old NCERT) - Question 8

Molecular hydrogen in presence of electric Arc is converted into atomic hydrogen. The enthalpy change for the reaction is 105.4 kcal/mol. This newly formed atomic hydrogen is very reactive and its half-life period is 0.33 seconds.

Test: Hydrogen (Basics) (Old NCERT) - Question 9

Which of the following mixture is known as water gas?

Detailed Solution for Test: Hydrogen (Basics) (Old NCERT) - Question 9

The mixture of carbon monoxide and hydrogen produced by a synthetic gas is known as water gas. This is from the water gas shift reaction, which was created by a physicist from Italy. Water gas is made by blowing steam through white-hot coke.

Test: Hydrogen (Basics) (Old NCERT) - Question 10

What is the process of producing syngas from coal known as?

Detailed Solution for Test: Hydrogen (Basics) (Old NCERT) - Question 10

As the mixture of carbon monoxide and hydrogen is used for the synthesis of methanol and a number of Hydrocarbons, it is called synthesis gas or syngas. The process of reducing syngas from coal is known as coal gasification.

Test: Hydrogen (Basics) (Old NCERT) - Question 11

What are the products in the water gas shift reaction?

Detailed Solution for Test: Hydrogen (Basics) (Old NCERT) - Question 11

At 773 Kelvin in the presence of ferric oxide and chromium oxide, the water gas (carbon monoxide and hydrogen) along with steam is transformed into carbon dioxide and hydrogen. This is also known as bosch process.

Test: Hydrogen (Basics) (Old NCERT) - Question 12

What are the reactants in Lane’s process?

Detailed Solution for Test: Hydrogen (Basics) (Old NCERT) - Question 12

In Lane’s process from superheated steam, iron filings are passed over and heated to about 1023 to 1073 Kelvin when hydrogen is formed. The concerned reaction is 3Fe + 4H2O → Fe3O4 + 4H2 at 1023-1073 K.
