1.Mohorovicic discontinuity marks the boundary between the upper mantle and the crust while the Gutenberg discontinuity marks the boundary between the lower mantle and outer core.
2.The Gutenberg discontinuity is located about 2900 km below the Earth surface whereas the Mohorovicic discontinuity is 8 km below the ocean floor and 30 to 50 km beneath typical continents.
3.Andriza Mohorovicic discovered the Mohorovicic discontinuity whereas Beno Gutenberg discovered the Gutenberg discontinuity.

Structure of Water Molecule
In water molecule, the oxygen is sp3 hybridized and hence has 4 sp3 hybridized orbitals. Two of these sp3 orbitals are half filled and hence overlap with 1s orbital of hydrogen to form two sp3 -s , O-H , σ bond while the other two contain a lone pair of electrons each.
The geometry of water molecule should be tetrahedral and the bond angle ∠HOH should be 109.5° but experimentally it has been determined that the actual bond angle is 104.5°.
Reason:

In water, the oxygen atom is surrounded by two shared pair ,and two lone pair of electrons. According to valence shell electron pair repulsion theory, lone pair- lone pair repulsion are stronger than Bond pair – Bond pair repulsion. As a result the bond angle in water is slightly smaller than the regular tetrahedral angle of 109.5°.The actual bond angle is 104.5° and each O-H bond has a bond length of 95.7pm.
<center> </center>In the gaseous state, water exist as discrete molecules. It is a bent molecule with bond angle of 104.5° and bond length of 95.7 pm.
The electronegativity of oxygen is much higher than that of hydrogen and hence the shared pair of electrons in O-H bonds are attracted slightly more towards the oxygen atom. As a result oxygen carries a partial negative charge and hydrogen atoms carrier a partial positive charge. Since these two dipoles are inclined to each other at an angle of 104.5° therefore water is a highly polar molecule its actual dipole moment is 1.84 D.

Suppose volume of 10 M HCl required to prepare 1 L of 6 M HCl = x litre
Volume of 3 M HCl required = (1-x) litre
Applying molarity equation:
Therefore Vol. of 10 M HCl required = 0.428 L = 428 mL.
Vol. of 3 M HCl required = 1-0.428 = 0.527 L = 572 mL

On July 7, HRD Minister Ramesh Pokhriyal announced a major CBSE syllabus reduction with 30% of the syllabus slashed for the year 2020-21 for classes 9 to 12 because of the reduction in classroom teaching time due to the Covid-19 pandemic and lockdown.
CBSE has rationalized the syllabus with the help of suggestions from NCERT and the same has been notified by a new CBSE notification as well.

• The history of geographical thought as mother branch of geography is included universally in its curricula.
• All the social science disciplines, viz. sociology, political science, economics and demography study different aspects of social reality.
• Geography and Civics: The core concern of political science is territory, people and sovereignty while political geography is also interested in the study of the state as a spatial unit as well as people and their political behaviour.
• Geography and Economics: Economics deals with basic attributes of the economy such as production, distribution, exchange and consumption are part of economic geography.
