Response: The cause of periodicity in properties is the repetition of similar outer electronic configuration after specific typical intervals.
since the addition of one or more electrons would lead to enhanced repulsion Among the many electrons and also a minimize in efficient nuclear charge.
Explanation: A switch controls the circulation of recent in a circuit by making or breaking the link. It doesn’t make any difference if it’s linked to the neutral or live wire; the key is completing or interrupting the circuit. The working of swap is not really dependent on the potential of Neutral wire.
It’s understood within the problem that the angles from the polygon will kind an A.P. with a typical variance d
Response: Each time a chemical bond is shaped by the whole transfer of electrons from one atom to a different, In order to accomplish their outermost shell and so, aquire the steady noble fuel configuration, the bond shaped is named ionic bond or electrovalent bond. ‘
Rationalization: Ice has significant particular latent heat of fusion. Meaning, it requires a ton of heat to melt.
ISC Board Exam has a global Conventional as well as their learners must be often all set to confirm they belong to a school or board which includes a global high-quality of instruction.
Comparing the pH of solutions of solid and weak acids of identical concentration. Δ Review the pH alter while in the titration of a robust base employing universal indicator.
Cause (R): The features of the picture shaped are that it could be taken with a display screen and is also diminished in sizing.
No matter whether CBSE Class 12 preparing for examinations or finishing assignments, these answers really are a worthwhile source for attaining tutorial good results in Class 11 Math.
The 5 sp3 d hybrid orbitals are directed in the direction of the five comers in the trigonal bipyramidal. For this reason, the geometry of PCl5 is usually represented as:
Clarification: Each time a is connected to favourable terminal on the battery, the current will flow in anticlockwise way within the facial area in close proximity to to another iron bar. As a result, the deal with nearer to another bar will become north pole.
ISC Class eleven has a multitude of topics that college students can choose from and pair together. Those people with a inclination to small business and finance can batch Commerce, Accounts and Economics even though the students having a wish to pursue health-related science can select biology, chemistry or biotechnology.
Query 21. Other than tetrahedral geometry, A further attainable geometry for CH4 is square planar Using the 4 H atoms for the comers on the sq. and the C atom at its centre. Explain why CH4 is not sq. planar?
