These notes contain all information about biomagnification, bioaccumulation, and bioconcentration. The factors(majorly pollutants) that cause them and the effect of this biomagnification on humans.

These notes will provide you with the theories of chemical bonding which include: Valence bond theory (VBT) Molecular orbital approach (MOT) Localized and delocalized (non-localized) approaches to bonding Orbital hybridization Concept of resonance (mesomerism) Hydrogen bonding I hope these notes will clear your concepts regarding chemical bonding. Thanks!!!!

These notes include a detailed discussion on Chemical bonding and types of chemical bonding in inorganic compounds. Types of Chemical bonding include: Ionic bond Covalent bond Coordinate covalent bond Metallic bond etc. These notes provide complete information about chemical bonding in inorganic compounds. After reading these notes your concept regarding chemical bonding will be cleared. Thanks!!!!

This document will definitely help you to understand the concept and types of scale of measurement. Data collection requires that we make measurements of our observation. scales of measurement are of different types. you can learn a lot of concepts from this document as i learnt.
