Study Notes

Rashtriya Avishkar Abhiyan (RAA) - Science Olympiad Club

RAA is a science Olympiad club that aims to promote scientific knowledge and skills among students.

Chemical Reactions and Equations

Chemical reactions involve the transformation of reactants into products.
Chemical equations represent chemical reactions, with reactants on the left and products on the right.
Examples of chemical reactions include combustion, oxidation, and acid-base reactions.

Stoichiometry

Stoichiometry is the study of the quantitative relationships between reactants and products in chemical reactions.
Mole concept is used to express the amount of substances in a chemical reaction.
Examples of stoichiometry problems include calculating the amount of reactants required for a reaction and the amount of products formed.

Physics

Motion can be described in terms of distance, displacement, speed, velocity, and acceleration.
Velocity is the rate of change of displacement, and acceleration is the rate of change of velocity.
Force is a push or pull that can cause an object to change its motion.

Biology

Cells are the basic units of life and are composed of organelles, including the nucleus, mitochondria, and ribosomes.
Photosynthesis is the process by which plants convert light energy into chemical energy.
DNA is the genetic material that contains the instructions for the development and function of an organism.

Environmental Science

The environment is composed of the natural world, including living and non-living components.
Human activities, such as pollution and habitat destruction, can impact the environment and ecosystem.
Conservation efforts, such as recycling and sustainable resource management, are important for protecting the environment.

Analytical Chemistry

Analytical chemistry is the study of the qualitative and quantitative analysis of substances.
Chromatography is a separation technique used to analyze mixtures of substances.
Spectroscopy is a technique used to analyze the interaction between matter and electromagnetic radiation.
