All of the important topics with the assessment can even be checked from the ISC 2025 syllabus. ICSE 12th syllabus 2025 is segregated into idea and functional papers. The weightage for every paper differs as per issue.
Rationalization: When light ray emerges in the prism, it travels from denser to rarer medium. Based on the rule of refraction, it's going to bend faraway from the conventional. Hence, angle of refraction are going to be greater than angle of incidence at that surface area.
This will arise in two means; by transfer of one or more electrons from a person atom to other or by sharing of electrons concerning two or more atoms.

There are several topics A part of class 12th and all of these are very important for students depending on their decided on stream. The detailed syllabus allows The scholars and guides them properly from the preparation for the Examination.
electron gain enthalpy is negative or positive it relies upon upon the nature of your element. For example. For halogens it is very damaging, since they can get the noble gas configuration by accepting an additional electron.
Respond to: Dobereiner organized selected factors with identical Qualities in teams of 3 in such a way the atomic mass of the middle aspect was virtually the same as the typical atomic masses of the 1st and 3rd components.
The upper steadiness from the wholly filled noble gas configuration results in extremely substantial 2nd ionisation enthalpy for sodium. However, Ma+ formed following losing initially electron even now has yet another electron in its outermost (3s) orbital. Consequently, the 2nd ionisation enthalpy of magnesium is far CBSE Class 11 Biology smaller than that of sodium.

Question 35. Anything at all that influences the valence electrons will impact the chemistry from the ingredient. Which one among the subsequent elements doesn't influence the valence shell?
In predicting the nature of the molecules: Molecules with unique dipole times are polar in nature and people of zero dipole moments are non-polar in mother nature.
The primary electron get enthalpy of oxygen is damaging for the reason that Vitality is introduced any time a gaseous atom accepts an electron to type monovalent anion.
