Vp Classes answered |
Methane has its molecular formula CH4.
It is formed by one carbon atom and four hydrogen atoms.
Hydrogen has its valency 1 and carbon being tetravalent needs four valence electrons to acquire noble gas configuration, where it shares its 4 electrons with four hydrogen atoms.
Therefore, the valency of carbon atom in Methane (CH4) is 4.

Pooja sengupta answered |
When 2 molecules of different electronegativity are bonded together covalently the bonding electron cloud is more attracted towards atom with higher electronegativity. ... So, the bond between 2 Oxygen atom is non-polar . Since, it is the only bonding in oxygen molecule Oxygen molecule is non-polar

Rajiv Gupta answered |
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

EduRev Class 10 answered |
- Option A: Menocchio - Protestant Reformation
Explanation: Menocchio was an Italian miller who reinterpreted the Bible's message and faced the Roman Catholic Church's inquisition for his controversial views. He was not directly associated with the Protestant Reformation. Therefore, this pair is incorrectly matched. - Option B: Martin Luther - Ninety-Five Theses
Explanation: Martin Luther is well-known for writing the Ninety-Five Theses in 1517, which criticized the practices of the Roman Catholic Church and played a crucial role in sparking the Protestant Reformation. This pair is correctly matched. - Option C: Louise-Sebastien Mercier - Index of Prohibited Books
Explanation: Louise-Sebastien Mercier was an 18th-century French novelist who advocated for the impact of books in spreading progress and enlightenment. He did not establish the Index of Prohibited Books, which was created by the Roman Catholic Church to regulate and control the reading material deemed heretical. Therefore, this pair is incorrectly matched. - Option D: Richard M. Hoe - Offset Press
Explanation: Richard M. Hoe from New York perfected the power-driven cylindrical press in the mid-19th century. The offset press, however, was introduced later in the 19th century. Therefore, this pair is incorrectly matched.
