Chemistry (Rasayan Vigyan)

Chemistry (Rasayan Vigyan) Chemistry mein reaction balance karna aur carbon ke compounds sabse zyada scoring hote hain. Chemical Reactions and Equations: Types of reactions (Combination, Decomposition, Displacement) aur Redox reactions par dhyaan dein. Carbon and its Compounds: Isme Versatile nature of Carbon, Homologous series, aur Saponification (sabun banane ki prakriya) bahut important hain. Acids, Bases and Salts: pH scale ka mahatva aur salts jaise Baking Soda, Washing Soda aur Plaster of Paris ke formulas aur uses yaad karein.
